Second version (V2) of the WD50Q, a quartz Fifty Fathoms-style diver. Brand specs: VH31 sweep-seconds quartz, polished 316L steel, 38mm without crown, 46mm lug-to-lug, 11mm including the crystal, 20mm lugs, bubble boxed sapphire with clear AR coating (side not stated), 120-click unidirectional bezel, BGW9 lume on hands and markers, screw-down crown and caseback, 200m. The brand says the bezel insert is "curved sapphire with BGW9 lume or flat ceramic depending on variant", but every current SKU names a glass (sapphire) bezel, so sapphire is recorded. The Purple SKUs say black bezel, while the photos show a purple bezel, so its bezel colour is left blank. Each dial comes on an FKM rubber strap ($109) or a beads-of-rice bracelet ($129); all options were in stock on 2026-10-24. Bracelet clasp and weight are not stated.
