Its 44 mm CARBONOX™ case delivers exceptional durability while weighing only 50 g. The distinctive crown guard, mirrored on the opposite side, recalls the silhouette of a sea turtle. A matte black dial with bold white numerals ensures clarity, shielded by a hardened mineral crystal.
The Swiss Ronda 515 quartz movement provides reliable precision with a battery life of up to 50 months. Luminox Light Technology (LLT) maintains a constant glow for 25 years without charging or light exposure. A unidirectional rotating bezel with a lumed marker at 12 o’clock adds practical timing capability. Completing the build, a polyurethane strap with a stainless-steel buckle balances comfort and resilience.
With CO₂-neutral production and a design made for endurance, the Sea Turtle Giant “Blackout” is a dependable choice for professional, tactical, or everyday use.
