Design and wearing experience
The 45.5mm round stainless-steel case and 180g weight create a deliberately substantial presence. The black dial, silver bracelet and silver case provide a versatile sport-watch appearance, while the 22mm lug width reinforces its larger proportions.
The 316L stainless-steel bracelet is finished with a folding clasp incorporating safety and diver-extension features. That arrangement is practical for secure wear and gives the watch added flexibility over a diving suit or thicker clothing.
Timing, clarity and durability
The ETA G10.212 quartz movement provides chronograph timing alongside date, small seconds and an end-of-life indicator. This is a practical specification for buyers who want timing functionality with straightforward day-to-day operation.
A sapphire crystal with double-sided anti-reflective coating is a strong durability and readability feature. Super-LumiNova hands and markers support visibility in darker conditions, while the 300m water-resistance rating and unidirectional aluminium bezel give the watch genuine dive-watch credentials.
