Dive-ready construction
The watch is built around a 45.5mm 316L stainless-steel case with black PVD coating and a unidirectional rotating aluminium bezel. Its 300m (30 ATM) water resistance gives it genuine capability for swimming, snorkelling and demanding water exposure.
A sapphire crystal with double-sided anti-reflective coating provides a durable, clearer viewing surface. The black rubber strap is a practical match for an active watch because it is flexible and suitable for wet conditions.
Chronograph functionality and visibility
The ETA G10.212 quartz movement supports a chronograph with 60-second, 30-minute and 12-hour sub-dials, alongside a date display and standard timekeeping functions. This gives the watch more utility than a simple three-hand diver.
Super-LumiNova hands and indexes are designed to support low-light legibility, while the black dial and black case create a cohesive, purposeful appearance. At 109g, it has a noticeable presence without being exceptionally heavy for its size.
Size and suitability
The 45.5mm diameter and 12.8mm thickness make this a commanding watch for buyers who favour large sports designs. The 22mm lug width and buckle clasp complete a straightforward, activity-focused layout.
The available product information supports a strong fit for water sports and everyday active wear. Buyers with smaller wrists or a preference for understated watches should consider the dimensions carefully before choosing it.
