With 44 mm in diameter they are designed for rather large wrists. Starting out there are two models, the first with the whole case was in PVD and the second the case is in brushed steel. They all have in common the case with the winding crown positioned at 3 o'clock, the crown at 10 o'clock to manage the internal ruler and finally the rotating bezel to monitor the residual immersion time adjustable to 120 micro-clicks. The glass is in anti-reflective sapphire. The steel model offers a black dial or in three color variations. The rather simple graphics with luminescent “glass” indexes, an unmistakable symbol of the underwater watchmaking world. The two large hour and minute spheres are surrounded by a thicker outline. The black model has a more gritty look. The matching bracelet is in hypoallergenic silicone with color combined with the dial. Animating them is a Miyota 8215 self-winding movement with three-hand and date functions. This caliber can also be wound manually.
