Founded in Grenchen, Switzerland in 1856, Eterna is one of the oldest watch manufacturers in the country and the inventor of the ball-bearing rotor — a movement innovation so fundamental that it was later licensed to the entire industry and still underpins most automatic watches made today. The Royal KonTiki, named after Thor Heyerdahl's legendary 1947 Pacific raft expedition, has been Eterna's flagship sports watch since the 1970s. The GMT variant brings a second time zone to that heritage platform, powered by Eterna's own manufacture movement.

Reference 7740.40 is a 42.3 mm stainless steel automatic GMT watch, 13 mm in thickness, with a brushed and polished case and a distinctive five-pointed bezel — a direct reference to the Eterna brand emblem. The dark anthracite dial carries luminescent stick hour markers and matching hands, with an arrow-shaped GMT hand for instant second time zone reading and a date window at three o'clock. At its heart beats the Eterna Manufacture Calibre 3945A, a 30-jewel automatic movement with a 65-hour power reserve, visible through the sapphire exhibition caseback. The scratch-resistant sapphire crystal carries anti-reflective coating. The fixed five-point bezel is in brushed stainless steel. Water resistance is rated to 100 metres. The watch is presented on a black rubber strap with a stainless steel pin buckle.

This Eterna Royal KonTiki GMT is in good condition and comes in the Eterna box, manual & QW warranty card.

Tudor was founded in Geneva in 1926 as a sister brand to Rolex, built to offer Swiss-made professional tool watches at a more accessible price point. The Pelagos Ultra, introduced in 2025, takes the Pelagos formula to its logical extreme — a watch built around a single brief: to go deeper than anything Tudor has produced before. With 1,000 metres of water resistance and a COSC and METAS-certified manufacture movement, the Pelagos Ultra makes a serious case for being the most capable production diver's watch at its price point.

Reference M2543C1A7NU-0001 is a 43 mm fully titanium automatic diver's watch, 14.5 mm in thickness, with a satin-finished case and a helium escape valve at ten o'clock. The matte black dial carries a sandblasted flange, Tudor's signature snowflake hands and square luminescent hour markers for maximum underwater readability. At its heart beats the Tudor Manufacture Calibre MT5612-U, both COSC and METAS-certified, with a 65-hour power reserve. The domed sapphire crystal sits above a solid titanium caseback. The unidirectional rotating bezel is titanium-framed with a matte ceramic insert and luminescent diving scale. Water resistance is rated to 1,000 metres. The watch is fitted on a titanium three-link bracelet with Tudor's T-fit folding clasp, safety catch and diver's extension with visual indicator system, and includes a black rubber strap with pin buckle and diver's extension.

Presented in very good condition, this Tudor Pelagos shows only minor signs of wear on the clasp and caseback. Accompanied by its full set (diver part of rubber strap missing).

Founded in Saint-Imier in 1884, Breitling extended its precision instrument philosophy from aviation to the deep sea — and the Superocean Heritage is where those two worlds meet most elegantly. Introduced as a tribute to the original Superocean of the 1950s, the Heritage II brings a vintage-inspired aesthetic to a thoroughly modern specification. The green dial variant has become one of the most sought-after colour executions in the collection — a bold choice that manages to feel both classic and contemporary at once.

Reference AB2010 is a 42 mm stainless steel automatic diver's watch, 14.35 mm in thickness, with a screw-locked crown fitted with two gaskets and a solid screwed-in caseback. The green dial carries applied luminescent stick hour markers, luminescent hands with hollow centres and a date window at six o'clock. At its heart beats the Breitling Calibre B20, an in-house manufacture movement with a 70-hour power reserve. The cambered sapphire crystal is glareproofed on both sides. The unidirectional ratcheted rotating bezel carries a black ceramic insert. Water resistance is rated to 200 metres. The watch is presented on a black (uncut) rubber Ocean Classic strap with a stainless steel folding deployant clasp.

This Breitling Superocean Heritage is in near mint condition and comes as a full set.

Founded in Le Locle in 1889, Doxa built its legend in 1967 with the SUB 300 — a professional diving instrument developed in close collaboration with Jacques-Yves Cousteau and one of the first watches to carry a no-decompression limit scale on its bezel. In 1969, a young Clive Cussler left his dive shop job with a DOXA SUB 300T as a parting gift. He never forgot it — the orange-dialled Doxa appeared again and again in his bestselling Dirk Pitt adventure novels, earning the brand a devoted following among readers and collectors worldwide. The SUB 300 Ti5 Clive Cussler, limited to 300 numbered pieces, is the most technically advanced tribute to that story yet produced.

Reference 823.50.121.20-SE14 is a 42.5 mm Grade 5 titanium automatic diver's watch, 13.4 mm in thickness, with a lug-to-lug distance of 45 mm, a screw-down Grade 5 titanium crown and a caseback engraved with the NUMA emblem — a nod to the fictional National Underwater and Marine Agency from Cussler's novels. The dial is an entirely new construction for Doxa: two superimposed layers of Grade 5 titanium, the upper laser-cut to reveal Super-LumiNova hour markers and indices beneath, creating genuine physical depth in the dial surface. A sandblasted finish plays light and shadow across the titanium, while signature DOXA orange highlights the oversized minute hand and the no-decompression limit scale on the bezel. A date window completes the layout. At its heart beats the Sellita SW200-1, COSC-certified, running at 28,800 vph with a 38-hour power reserve, decorated by Doxa. The domed glass-box sapphire crystal carries an anti-reflective coating. Water resistance is rated to 300 metres. The watch is presented on a black Dive Flex rubber strap with a pin buckle.

This Doxa SUB 300 Ti5 Clive Cussler Limited Edition is in mint condition and comes as a full set.

Grand Seiko was established in 1960 with a single ambition: to produce the finest watch Seiko's craftsmen could create. The Sport Collection brings Grand Seiko's legendary finishing standards — Zaratsu-polished surfaces, precisely applied indices — to a professional diving instrument. The SBGA229 is one of the most compelling sports watches the brand has ever produced: a watch that could sit alongside any Swiss diver at twice the price and not feel outclassed.

Reference SBGA229 is a 44.2 mm stainless steel automatic diver's watch, 14 mm in thickness, with a fully Zaratsu-polished and faceted case that plays light across its curves in a way no conventionally brushed diver's case can match. The black dial carries arrow-shaped hands and swaged LumiBrite indices for strong underwater legibility, with a power reserve indicator and a date window. At its heart beats the Grand Seiko Calibre 9R65, a Spring Drive movement combining automatic winding with an electromagnetic braking system that delivers ±1 second per day accuracy and a 72-hour power reserve. The unidirectional rotating bezel carries a titanium carbide ceramic insert — the same class of material used to protect spacecraft during atmospheric re-entry. The screw-down crown and caseback are engineered so that dirt, sand and seawater residue can be easily rinsed away. Water resistance is rated to 200 metres. The watch is fitted on a stainless steel bracelet with a three-fold clasp.

This Grand Seiko Sport Collection Spring Drive Diver is in very good condition and comes as a full set.

Founded in Saint-Imier in 1884, Breitling built the Navitimer in 1952 as the definitive pilot's chronograph — and it has remained in continuous production ever since, longer than almost any other sports watch in history. The current Navitimer 41 is the most refined and wearable generation yet: a slimmer, more elegant execution of the original that sacrifices nothing of the aviation instrument character that made the Navitimer famous. The U17326 is the steel and 18k rose gold expression — a two-tone combination that brings a quiet warmth to an otherwise entirely purposeful design.

Reference U17326 is a 41 mm stainless steel automatic watch, 10 mm in thickness, with a polished and brushed case and a solid screwed-in caseback engraved with the Breitling logo. The silver dial carries applied rose gold baton hour markers and luminescent hands, with a rose gold red-tipped central seconds hand and a date window at six o'clock. The bidirectional revolving bezel is crafted in 18k rose gold and carries the Navitimer's signature circular slide rule for aviation calculations. At its heart beats the Breitling Calibre 17, COSC-certified. The cambered sapphire crystal is glareproofed on both sides. Water resistance is rated to 30 metres. The watch is presented on a brown leather strap with a stainless steel folding deployant clasp.

This Breitling Navitimer Automatic 41 Steel & Rose Gold is in mint condition and comes as a full set.

Founded in La Chaux-de-Fonds in 1791, Girard-Perregaux is one of the oldest continuously operating watch manufactures in Switzerland. The Laureato, introduced in 1975, was one of the first integrated bracelet sports watches to emerge in the wake of the Audemars Piguet Royal Oak — and one of the most elegant. Its octagonal bezel with visible screws and integrated bracelet give it a geometric character that has only grown in appeal over five decades. The current 42 mm generation, reintroduced in 2016, brought the Laureato fully back into the conversation as one of the most refined sports watches in its segment.

Reference 81010-11-231-BB6A is a 42 mm stainless steel automatic watch, 10.88 mm in thickness, with a brushed case and octagonal bezel with polished bevelled corners. The grey dial carries a fine hobnail Clous de Paris guilloché texture, applied hour markers and luminescent stick hands, with a date window at three o'clock. At its heart beats the Girard-Perregaux Calibre GP01800, an in-house automatic movement visible through the sapphire exhibition caseback. The scratch-resistant sapphire crystal sits above. Water resistance is rated to 100 metres. The watch is presented on a black alligator leather strap and includes an additional black rubber strap, both with stainless steel deployant clasps.

This Girard-Perregaux Laureato Automatic 42 is in very good condition and comes as a full set.

Founded in Saint-Imier in 1884, Breitling built its reputation on precision instruments for aviation and professional use before extending that same engineering philosophy to the deep sea. The Superocean, one of the brand's most enduring dive watch lines, traces its visual DNA back to the iconic Slow Motion chronograph of the 1960s. The Rainbow edition, introduced in 2021, brings a bold and playful twist to that heritage: a black dial with hour markers and hands coated in a full spectrum of Super-LumiNova colours that cycle through yellow, green, blue, indigo, violet, red and orange — visible in daylight as a subtle multicolour gradient and underwater as a genuinely remarkable display of luminescence.

Reference A17375211B2S4 is a 42 mm stainless steel automatic diver's watch, 12.56 mm in thickness, with a screw-locked crown fitted with two gaskets and a screwed-in caseback. The black dial carries broad polished hands and applied hour markers, all coated in the full rainbow Super-LumiNova graduation. At its heart beats the Breitling Calibre 17, COSC-certified. The cambered sapphire crystal is glareproofed on both sides. The unidirectional ratcheted bezel carries a black ceramic insert with a 60-minute diving scale. Water resistance is rated to 300 metres. The watch is presented on a yellow rubber strap with a stainless steel micro-adjustable folding clasp.

This Breitling Superocean Automatic 42 Rainbow is in near mint condition and comes as a full set with a new and uncut rubber strap.

Founded in Tokyo in 1946, Casio transformed consumer electronics before launching the G-Shock in 1983 with one goal: to build an indestructible watch. The MR-G sits at the very top of that story — hand-assembled at Casio's Premium Production Line in Japan, where aerospace-grade alloys meet the kind of surface finishing normally associated with Swiss haute horlogerie. The MRG-B2100D-2A takes its identity from "Hanada-iro", a traditional Japanese hue expressing the calm of a mountain pagoda seen through morning mist — rendered here across a dial inspired by the kigumi lattice pattern of Japanese woodcraft.

Reference MRG-B2100D-2A is a 44.4 mm MR-G automatic analogue watch, 13.6 mm in thickness and weighing just 122 grams despite its full-metal construction. The indigo blue dial carries a three-dimensional kigumi-inspired geometric pattern, with diamond-polished hour markers and hands coated in Neobrite for low-light readability. The Ti64 titanium case and bezel carry a titanium carbide coating for scratch resistance, while the top bezel is crafted in COBARION — a cobalt-chrome alloy four times harder than pure titanium and finished with Casio's Sallaz mirror-polishing technique. The DAT55G titanium bracelet links are individually polished and fitted with a tight-lock one-press three-fold clasp. The Tough Solar movement powers Multi-Band 6 radio-controlled time synchronisation across six global atomic clock transmitters, Bluetooth smartphone link via the Casio Watches app, and a full perpetual calendar. The sapphire crystal carries an anti-reflective coating. Water resistance is rated to 200 metres.

This Casio G-Shock MR-G Hanada-iro is in near mint condition and comes as a full set.

Founded in La Chaux-de-Fonds in 1848, Omega has built one of the most storied reputations in Swiss watchmaking — as official timekeeper of the Olympic Games and the brand worn on the Moon during all six Apollo landings. The Dark Side of the Moon series, launched in 2012, took the Speedmaster's space heritage literally: a collection built from advanced materials in bold configurations that no conventional Moonwatch could match. The "Grey Side of the Moon" Meteorite is the most extraordinary expression of that idea — a watch whose dial is cut from a piece of ancient extra-terrestrial stone that landed on Earth after billions of years drifting through space.

Reference 311.63.44.51.99.001 is a 44.25 mm grey ceramic automatic chronograph, 16.1 mm in thickness, with a brushed and polished case and bevelled edges. The meteorite dial is solid — cut from genuine iron-nickel meteorite and acid-etched to reveal its unique Widmanstätten crystalline pattern, meaning no two dials are ever identical. 18k Sedna gold hands sit above the surface with luminescent fill. A 60-minute and 12-hour counter sit at three o'clock, a small seconds subdial at nine and a date window at six. At its heart beats the Omega Co-Axial Calibre 9300, visible through the sapphire exhibition caseback. The fixed 18k Sedna gold CeraGold bezel carries the brushed tachymeter scale. Water resistance is rated to 50 metres. The watch is presented on the alligator leather strap with a ceramic and titanium foldover clasp and an additional Omega alligator leather strap. 

This Omega Speedmaster Dark Side of the Moon Meteorite is in near mint condition and comes as a full set.

Atowak is a young independent watch brand with a clear and uncompromising design philosophy: to create mechanical watches that challenge the conventions of how time is displayed. The Cobra, launched in 2022 and limited to 500 numbered pieces, is the brand's defining statement — a watch that won both the 2023 Muse Design Award and the 2024 German IF Design Award and introduced one of the most visually striking time display systems in independent watchmaking.

Reference AK801SJSBL is a 43 mm stainless steel automatic watch, 16.2 mm in thickness, with a 316L stainless steel case decorated with carbon fibre patches and a signature cobra-head case shape with the crown positioned at twelve o'clock. The royal blue dial is constructed from 3D copper and aviation-grade aluminium with a Geneva woven surface pattern, with Swiss Super-LumiNova on the numerals and minute scales. Time is read via Atowak's patented 360°-revolving satellite hour wheel system: three aluminium and carbon fibre arms rotate continuously, each carrying an hour numeral that revolves 120° at a time to indicate the correct hour — a mesmerising display unlike anything in conventional watchmaking. At its heart beats a modified Miyota 9039 automatic movement. The dual sapphire crystal construction features a trapezoidal upper opening and a polygonal lower crystal, both scratch-resistant. Water resistance is rated to 30 metres. The watch is supplied with two wearing options: a royal blue leather strap with quick-release buckle and a 316L stainless steel bracelet with butterfly clasp, both tool-free swappable.

This Atowak Cobra Steel Royal Blue is in near mint condition and comes as a full set.

Founded in Saint-Imier in 1832, Longines is one of the oldest Swiss watch brands in continuous production and has built a deep archive of iconic designs across more than 190 years. The Legend Diver, introduced in 2007, is a faithful reissue of the brand's original Reference 7042 dive watch from 1960. 

Reference L3.674.4.50.0 is a 42 mm stainless steel automatic diver's watch, 13.5 mm in thickness, with a distinctive twin-crown construction: one crown for time setting and one dedicated to operating the inner rotating bezel — a period-correct feature that sets the Legend Diver apart from virtually every other tool watch of its era and price point. The black lacquered dial carries luminescent index and Arabic numeral hour markers alongside matching silver-tone hands, with a date window at three o'clock. At its heart beats the Longines Calibre L633. The scratch-resistant sapphire crystal and screw-down twin crowns deliver 300 metres of water resistance. The bidirectional rotating inner bezel is operated via the dedicated secondary crown at four o'clock. The solid caseback carries the embossed Longines diver emblem. The watch is comes on the original stainless steel mesh bracelet.

This Longines Legend Diver is in very good condition and comes as a full set.
