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 is Tudor’s most serious diving instrument — developed with genuine professional credentials and a titanium case that makes it both lighter and stronger than its steel peers. The LHD, or Left Hand Drive, is its most unconventional expression: a fully mirrored version of the Pelagos with the crown repositioned to nine o’clock, drawing a direct line to a rare left-handed Tudor Submariner produced for the French Navy in 1981. Each piece carries a unique individual production number engraved on the caseback.

Reference M25610TNL-0001 is a 42 mm titanium automatic diver’s watch, 14.45 mm in thickness, with a satin-finished case and a screw-down crown at nine o’clock bearing the Tudor logo in relief. The black dial features the “Pelagos” designation printed in red — a distinctive detail unique to the LHD — alongside beige-toned LumiBrite on the hands and snowflake hour markers, and an alternating red and black date wheel in which even-numbered days appear in red and odd-numbered days in black. A helium escape valve sits at three o’clock. At its heart beats the Tudor Manufacture Calibre MT5612-LHD, a COSC-certified automatic movement mirrored specifically for left-hand crown positioning, with a 70-hour power reserve. The domed sapphire crystal sits above a solid caseback. The unidirectional rotating bezel carries a matte black ceramic insert. Water resistance is rated to 500 metres. The watch is fitted on a titanium bracelet with Tudor’s patented extension system and a steel folding clasp with safety catch, and includes an additional black rubber strap.

This Tudor Pelagos LHD is in very good condition and comes as a full set with factory warranty until July 2031.

Founded in Saint-Imier in 1884, Breitling extended its precision instrument philosophy from aviation to the deep sea — and the Superocean is where that legacy lives most directly. The current generation draws its visual DNA from the iconic Superocean Slow Motion chronograph of the 1960s and 70s — clean lines, oversized indices, squared-off hands — distilled into a thoroughly modern dive watch built for serious use.

Reference A17376211B1A1 is a 44 mm stainless steel automatic diver’s watch, 12.6 mm in thickness, with a screw-locked crown and a solid caseback. The matte black dial carries broad applied hour markers and oversized hands, all heavily coated in Super-LumiNova for exceptional underwater legibility — with a subtle red accent on the Superocean text and the tip of the seconds hand, a nod to the original Slow Motion. At its heart beats the Breitling Calibre 17, COSC-certified. The cambered sapphire crystal is glareproofed on both sides. The unidirectional rotating bezel carries a scratch-resistant black ceramic insert. Water resistance is rated to 300 metres. The watch is fitted on a brushed and polished stainless steel Professional III bracelet with a fold-over deployant clasp and 15 mm micro-adjustment system.

This Breitling Superocean Automatic 44 is from 2023, is in unworn condition and comes as a full set.

Founded in Paris in 1847, Cartier stands at the very origin of the wristwatch as we know it. Louis Cartier designed the original Santos in 1904 for his friend Alberto Santos-Dumont — the Brazilian aviation pioneer who needed to read the time without releasing the controls of his aircraft — making it one of the first purpose-built wristwatches in history and the template from which the modern dress sports watch would eventually emerge. More than a century later, the Santos de Cartier remains in continuous production and continues to define the category it invented.

Reference WSSA0018 is the large model Santos de Cartier in polished and brushed stainless steel, measuring 39.8 x 47.5 mm with a thickness of just 9.08 mm. The white silvered dial carries black painted Roman numerals, a railway-track minute scale and sword-shaped hands in blued steel — unmistakably Cartier from across a room — with a date window at six o’clock. The eight exposed screws on the polished stainless steel bezel are both a structural and a design signature, drawn directly from the 1904 original. The seven-sided crown is set with a faceted synthetic spinel in the house’s signature blue. At its heart beats the Cartier Calibre 1847 MC, an in-house automatic movement with a 42-hour power reserve, visible through the transparent sapphire caseback. The scratch-resistant sapphire crystal sits above. Water resistance is rated to 100 metres. The watch is supplied with a polished and brushed stainless steel bracelet with Cartier’s QuickSwitch interchangeable system and an additional calfskin strap — both with a stainless steel folding deployant clasp.

This Cartier Santos de Cartier Large is in near mint condition and comes as a full set with factory warranty until 2030.

Founded in Paris in 1847, Cartier stands at the very origin of the wristwatch as we know it. Louis Cartier designed the original Santos in 1904 for his friend Alberto Santos-Dumont, the Brazilian aviation pioneer — making it one of the first purpose-built wristwatches in history. The Santos Galbée, whose name means ‘curved’ in French, is the most refined expression of that original design: a Santos with softened edges and a gently curved case and bracelet that moulds itself naturally to the wrist, combining the collection’s distinctive DNA with a more understated everyday character.

Reference 1566 is the medium model Santos Galbée in stainless steel and 18k yellow gold, measuring 29 x 41 mm with a thickness of just 6.7 mm. The silvered guilloché dial carries black painted Roman numerals, a railway-track minute scale and sword-shaped hands in blued steel — details that are unmistakably Cartier — with a discreet date window at six o’clock. The octagonal crown is set with a faceted synthetic sapphire cabochon. The fixed 18k yellow gold bezel is secured by the Santos’ hallmark exposed screws. The scratch-resistant sapphire crystal sits above a solid caseback. Water resistance is rated to 30 metres. The watch is comes on a brown leather strap with a Cartier deployant clasp.

This Cartier Santos Galbée is in very good condition. 

Founded in Saint-Imier in 1884, Breitling built its global reputation on precision chronographs for aviation and professional use. The Chronomat, originally developed in 1983 in collaboration with the Italian Frecce Tricolori aerobatic display team and relaunched with an in-house movement in 2009, is the model that defines Breitling’s character most completely — bold, mechanical, and built without compromise. The current B01 42 generation is the most accomplished Chronomat ever produced, combining the iconic case architecture with a fully in-house manufacture chronograph movement.

Reference AB0134101B1A1 is a 42 mm stainless steel automatic chronograph, 15.1 mm in thickness, with a brushed and polished case and the signature unidirectional rotating bezel with four rider tabs. The black dial carries polished applied stick hour markers and luminescent hands alongside three silver subdials: a 60-second register at three, a 30-minute counter at nine and a 12-hour counter at six, with a date window between the subdials at six. The black outer flange carries a tachymeter scale. At its heart beats the Breitling Manufacture Calibre B01, a column-wheel automatic chronograph movement with vertical clutch and COSC certification, delivering 70 hours of power reserve — visible through the sapphire exhibition caseback. The cambered sapphire crystal is glareproofed on both sides. Water resistance is rated to 200 metres. The watch is fitted on the signature Rouleaux stainless steel bracelet with a push-button folding clasp.

This Breitling Chronomat B01 42 is in near mint condition and comes as a full set with factory warranty until December 2033.

Officine Panerai was founded in Florence in 1860 as a supplier of precision instruments to the Italian Navy, and for decades its watches were produced exclusively for military use before opening to the public in 1993. The PAM00090 is one of the most coveted references in the classic Luminor line — a limited edition of 2,200 numbered pieces that added a practical power reserve indicator to the iconic Luminor architecture without disturbing the essential character that makes Panerai so distinctive.

Reference PAM00090 is a 44 mm stainless steel automatic watch, 14 mm in thickness, with Panerai’s signature cushion-shaped two-part case and the lever-operated crown-protecting bridge on the left side. The black sandwich dial carries luminous Arabic numerals at six and twelve alongside index hour markers and matching luminous hands — a construction that gives the dial genuine depth and outstanding legibility in low light. A small seconds register sits at nine o’clock, a date window at three, and a power reserve indicator at five o’clock for a quick read of remaining autonomy. At its heart beats the Panerai Calibre OP IX, a COSC-certified automatic movement based on the ETA 7750. The scratch-resistant sapphire crystal sits above a solid screw-down caseback. Water resistance is rated to 300 metres. The watch is presented with both the original orange rubber strap and a black leather strap, each with a stainless steel deployant clasp.

This Panerai Luminor Power Reserve Automatic is from 2008, is in very good condition and comes in the original Panerai box and warranty papers.

Since introducing Japan’s first diver’s watch in 1965, Seiko has built an unmatched heritage in professional dive watch design. The SJE097J1 was produced to mark a historic milestone: the 100th anniversary of Seiko-branded watches. Limited to just 1,000 numbered pieces worldwide, it draws simultaneously from two legends — the original 1965 62MAS that started it all, and the professional-grade Marinemaster of the 2000s that took Seiko’s dive watch standards to their highest point.

Reference SJE097J1 is a 39.5 mm stainless steel automatic diver’s watch, just 12.3 mm in thickness — the slimmest mechanical diver Seiko has ever produced, a remarkable achievement given the box-shaped sapphire crystal and the exhibition caseback it carries. The white “High Water” dial features a distinctive horizontal line pattern evoking moving water, with thick LumiBrite-coated baton hour markers, matching lume hands and the “Marinemaster” designation printed just below the Seiko logo at twelve. At its heart beats the Seiko Calibre 6L37, the first movement in Seiko’s new slim 6L series developed specifically for diver’s watches, with manual winding capability and a 45-hour power reserve. The box-shaped sapphire crystal carries anti-reflective coating on the inner surface — and the exhibition caseback, a historic first for a dedicated Seiko diver, shows the movement within alongside the individual serial number engraved on the caseback. The unidirectional rotating bezel carries a full LumiBrite diving scale. Water resistance is rated to 200 metres. The watch is fitted on a stainless steel bracelet with a three-fold clasp, push-button release and diver’s extension.

This Seiko Prospex Marinemaster 1965 High Water Limited Edition is in near mint condition and comes as a full set with factory warranty until 06-2027.

Founded in La Chaux-de-Fonds in 1848, Omega has built one of the most storied reputations in Swiss watchmaking. The Seamaster 300, introduced in 1957 alongside the Speedmaster and Railmaster as one of Omega's iconic sport watch trio, became one of the most respected professional diving instruments of its era. The "WatchCo" is a chapter in that story unlike any other: WatchCo, a former Omega-authorised Australian service centre, acquired genuine new-old-stock Omega parts — cases, bezels, dials and hands — directly from the manufacture and assembled them into complete watches around vintage Omega movements. The result is a watch with the full aesthetic and material authenticity of the original 1960s Seamaster 300, assembled with brand-new genuine Omega components, and a cult following that has only grown stronger as supply has dwindled.

Reference 166.0324 is a 41 mm stainless steel automatic diver's watch with the distinctive twisted-lug case architecture of the original Seamaster 300. The black dial carries oversized rhomboid luminescent hour indices and matching sword-shaped hands — a handset shared in spirit with the military Submariner references of the same era — with a date window at three o'clock. At its heart beats the Omega Calibre 565, a high-grade vintage automatic movement with quickset date function, running accurately and reliably. The domed acrylic crystal gives the watch the correct period-authentic depth and curvature. The bidirectional rotating dive bezel carries a luminescent insert. The watch is fitted on a stainless steel bracelet.

This Omega Seamaster 300 WatchCo presents in near mint condition and comes in the Omega service box with 1 year warranty

Founded in Saint-Imier in 1832, Longines is one of the oldest Swiss watch brands in continuous production and carries one of the deepest archives in the industry. The Spirit collection draws directly from Longines' rich aviation heritage — the brand produced precision instruments for pioneering aviators throughout the twentieth century — and the titanium variant represents the most technically resolved version of that idea: lighter than steel, stronger, non-reactive to the skin and with the darker matte character that the outdoors demands.

Reference L3.810.1.53.2 is a 40 mm Grade 5 titanium automatic watch, 12.2 mm in thickness, with a screw-down crown and solid caseback. The anthracite sandblasted dial carries applied Arabic numerals and gold-toned hands coated in Super-LumiNova, with a black satin-finish flange ring. No date window interrupts the clean layout. At its heart beats the Longines Calibre L888.4, COSC-certified with a silicon balance spring, delivering a 72-hour power reserve. The domed sapphire crystal carries multiple layers of anti-reflective coating. Water resistance is rated to 100 metres. The watch is presented on a black NATO-style fabric strap with Longines' quick-change system and a stainless steel pin buckle.

This Longines Spirit 40 Titanium is in near mint condition and comes as a full set with factory warranty until 2028. 

Since its inception in 1833, Jaeger-LeCoultre has been a beacon of Swiss watchmaking excellence, renowned for its innovative designs and technical mastery. The Reverso Duoface features a stainless steel case measuring 42.0 x 26.5 mm, embodying the iconic rectangular shape that has become synonymous with the Reverso line. Its unique reversible mechanism allows wearers to alternate between two distinct dials, catering to both aesthetic preferences and functional needs.

The Front Dial showcases a two-tone guilloché silver face adorned with black painted Arabic numerals and a subsidiary small seconds dial at the 6 o'clock position. The Reverse Dial presents an anthracite grey guilloché dial featuring an off-center time ring with luminous Arabic hour numerals, luminous hands, and a 24-hour second time zone indicator with a day/night aperture.

This Reverso Duoface comes in the original box and with a original JLC alligator strap & folding clasp. In 2025 it had a full service at Jaeger-LeCoultre with invoice.
