About this entry

87% of key specs known. Missing: lug-to-lug, hardening.

The SN038-Q listing sells one CuSn8 bronze diver with a choice of NH35 ($320), PT5000 ($345) or Sellita SW200 ($520), each with or without a date window ("With Calender" / "No Calender") at the same price; this file is the NH35 version and sn038-pt5000 and sn038-sw200 the others. The spec text names only the "domestic PT5000 and imported SW200"; the NH35 appears only in the option list. Brand specs: CuSn8, 44mm excluding crown, 15mm including crystal, 20mm lugs, sapphire with AR coating (side not stated), blue or green sunburst enamel or matte black dial with applied markers, C3 lume with a fully lumed bezel, screw-down crown (at 4 in photos), one-piece case with no separate caseback (recorded as monocoque) and a shark-pattern back, leather strap (brown for wrists under 7 inches, green above) with bronze pin buckle, 300m, about 150g (read as on the strap, the only option); lug-to-lug is not stated. The 60-minute bezel scale is from photos; direction and insert material are not stated. The date versions come with or without the San Martin logo (custom logos are offered only with the date), the no-date versions only with the logo. Because the store sells each movement with and without a date window, complications are left to the movement; how the no-date versions are built is not stated. The dial is printed "Marine Master Professional 300m", and the case with its crown at 4 follows Seiko's Marinemaster 300; inspired_by is read from the design and the dial text, as the brand does not name it. Every variation showed "Out of stock" on 2026-10-25, so production status is unknown.
