Updated based on the popular model BN015 series. This is a new saturation diving model that has evolved in design, functionality, and durability. Water resistant to 300m with a helium escape valve installed on the 2 o'clock side of the case to prevent damage to the watch and protect divers. Equipped with Cal.E365, the first diver model, it continues to operate for one year after a full charge, even in deep sea environments where light cannot reach. The crown, crown guard, index, and hour and minute hands follow the design of the BN015 series. Adopts a rotating bezel made of stainless steel that has an outstanding three-dimensional effect and power, and the bezel ring has been upgraded to 120 clicks for easy operation. The urethane band uses BENEBiOL, an environmentally friendly resin material that does not easily crack or break. Equipped with a high-performance movement, it is now possible to produce darker colors with lower transmittance than before. A subtle gradation reminiscent of the deep sea is applied to create a simple yet profound and powerful impression. As proof of the saturation diving model, there is a diving helmet pattern on the back cover and the words "300m PROFESSIONAL DIVER'S" engraved on the 9 o'clock side of the case. Release date: Released in April 2025
