About this entry
93% of key specs known. Missing: hardening.
The SN0025-JS listing ("self-designed limited edition", written "SN0025-T-JS" in its spec list; the edition size is not stated) is a chronograph version of the titanium SN025 octopus diver with an ETA 7753, one blue sunburst dial, $1,550. Brand specs: Grade 5 titanium, 45mm without crown, 46mm lug-to-lug, 19mm including crystal, 22mm lugs, sapphire with "Swiss AR coating" (side not stated), multi-faceted lumed hands, BGW-9 lume glowing ice blue, 8mm screw-in crown, embossed 3D octopus caseback (attachment not stated), shark skin strap with titanium buckle plus a fluorine rubber strap, 200m, about 130g (not stated what was weighed). The 46mm lug-to-lug is short beside the 49mm quoted for the three-hand SN025 case; it is recorded as stated. The photos show counters only at 3 and 9 (where the 7753 puts its 30-minute counter and small seconds) and no date window or 6 o'clock 12-hour counter, so complications are recorded from the photos. Whether the bezel rotates is not stated. The listing showed "Out of stock" on 2026-10-24.
