This Seiko Prospex MarineMaster 200 is called by Seiko "The 1968 Automatic Diver's Modern Re-interpretation SPB079". 

The SPB079 is the version with the stealthy blue bezel and comes standard on a silicone strap. This watch however also has the steel bracelet. At 44mm wide, 13.1mm thick, and 51mm lug to lug, the SPB079 wears not unlike a longer version of the much loved Prospex SRP777. The case is made of stainless steel and feature a screw-down case-back, rather than the monoblock construction of the SLA025 reissue. The curvy case shape, the narrow lugs, and the crown at four do carry over from the design of the original reference 6159. 

This Seiko also had a full service in 2022 and comes as a full set with the bracelet!
