About this entry

87% of key specs known. Missing: weight, hardening.

The SN0025 listing ("self-designed limited edition", in the store's SN025 category; the edition size is not stated) sells the 45mm SN025 case in Grade 5 titanium with a PT5000 (from $625) or a Sellita SW200 (from $715), with or without a date window and with or without the San Martin logo (a "Custom Logo" option is listed but has no orderable variation). This file is the PT5000 version, $625 for every option; see sn025-titanium-sw200 for the Sellita SW200 and sn025-pt5000 for the 316L SN025-G. Brand specs: Grade 5 titanium case machined by CNC, with the decorative bezel screws real and removable, 45mm without crown, 49mm lug-to-lug, 13.9mm including crystal, 22mm lugs, sapphire with AR coating (side not stated), mother-of-pearl dial (blue in the photos), multi-faceted "GS craft" hands, BGW-9 lume glowing ice blue, 8mm screw-in crown, embossed 3D octopus caseback (attachment not stated), leather-faced rubber strap with titanium buckle, 200m. No weight is given. One gallery photo shows "ETA" engraved on the caseback rim, but the listing sells only PT5000 and SW200 builds. Whether the bezel rotates is not stated. Because the store sells the watch both with and without a date window, complications are left to the movement. Every variation showed "Out of stock" on 2026-10-24.
