2025 Good Design Award Winner

Introducing the popular Marine series from CITIZEN 's Promaster sports line, which is available in three categories: land, air, and sea.

The BN015 series has been loved by many professionals since its launch in 2015, with features such as a crown at 4 o'clock and a rotating bezel with a unique silhouette.

While maintaining its identity, it has achieved a dramatic upgrade in specifications, with water resistance for saturation diving to 300m.

Equipped with a helium escape valve that allows helium, an extremely small atom that enters the watch, to escape to the outside, preventing the watch from exploding when pressure is reduced.

The rotating bezel has been upgraded to 120 clicks for a comfortable feel, and the bezel ring is made of stainless steel for a three-dimensional look.

Lugless design creates a smart look
The case and dial have a mysterious gradation that evokes the deep sea.

It also comes equipped with the E365 solar-powered movement, which can run for one year on a full charge.

The band is made of BENEBiOL, a recycled material that is resistant to hydrolysis. This material is resistant to chemical reactions and deterioration, making it durable enough to withstand the harsh conditions of the deep sea.

This professional model is perfect for professional use, so please come to our store and take a look.

All of our staff look forward to your visit.
