Design & Craftsmanship

Maritime Performance in a Balanced 40mm Silhouette

Historically, 300-metre dive watches have been engineered with heavy, oversized cases. In this 40.00 mm edition, Tissot provides an ergonomic mid-size profile that sits comfortably flush on a wide range of wrist sizes. The 316L surgical-grade stainless steel case features polished bevels and satin-brushed flanks, shielded by protective crown guards that prevent accidental knocks during athletic activity.

Sunburst Turquoise Dial & Luminous Readability

The gradient turquoise dial captures the vivid, clear tones of lagoon waters deepening toward the seabed. Accented with circular and baton-shaped applied indices, alongside wide sword hands generously filled with Super-LumiNova®, the dial delivers immediate legibility whether checking the time in midday glare or submerged in dark waters.

Swiss Quartz Dependability & HeavyDrive Technology

Beneath the dial beats the Swiss-made ETA F06.412 quartz calibre featuring HeavyDrive technology, which intelligently manages hand imbalances caused by physical shocks. Operating on a long-life Renata battery, the movement eliminates the need for daily winding while offering hassle-free, grab-and-go precision.
