DIVER 300m

With the crown at 4 o’clock and the rotating bezel’s distinctive silhouette, this model takes its overall design identity from the BN015 Series (a popular hit since its 2015 debut), while offering a serious spec upgrade in the form of 300m saturation-diving water resistance. The rotating bezel with its satisfying operating feel has been changed to 120 clicks and the bezel ring is now stainless steel for a more impactful three-dimensional effect. The use of a lugless case makes the model feel sleeker and more compact. This model promises to extend your scope of action to even greater depths.

This model is equipped with a helium escape valve which enables tiny helium atoms to escape from the inside of the watch to prevent it exploding during decompression. The valve opens the door to saturation diving, a kind of diving that requires equipment, skills and training far beyond those of ordinary divers. Thanks to 300m water resistance, the watch is capable of withstanding even the extreme conditions of saturation-diving zones.

This model is fitted with the Caliber E365, a state-of-the-art light-powered movement that runs for an entire year on just a single full charge. Even if you shut the watch away in a dark closet at the end of one summer, it will still be happily telling the time when you take it out again in summer next year! Thanks to advances in power-consumption characteristics, the dial can be less light-transmissible than before, allowing for a glossier and more luxurious dial design.

The dive helmet apparatus engraved in relief on the case back and the “300m PROFESSIONAL DIVER’S” lettering at the 9 o’clock position clearly identify this model as part of our proud line of saturation-diving models.

The band is made of BENEBiOl® a recycled material that boasts excellent hydrolysis resistance. Durable and non-reactive, BENEBiOl® is sufficiently tough to withstand the brutal deep-ocean environment over the long term.

The atmospheric gradient dial evokes the descent from the surface down into the ocean depths. Two colour options are available: glossy, handsome black (N1024-01E) and majestic crimson red (BN1024-01Z).
