A black face that gives a bold impression.

The dial is skeletonized with a window that allows a view into the Swiss automatic movement.

It has a date calendar (date display) at the 6 o'clock position, which is convenient for everyday use.

The date letters are also cut out, giving the design a greater sense of depth.

The hands and indexes are coated with Super-LumiNova® , ensuring high visibility even underwater or in the dark.

This professional-spec diver's watch is water resistant to 500m (50 bar), making it suitable for swimming and diving.

It also features a unidirectional rotating bezel and a helium escape valve, making it suitable for scuba diving and saturation diving.

The crown is screw-down to prevent water from entering.

The unidirectional rotating bezel used to measure elapsed time is a count-up type.

Running out of oxygen in a tank can be life-threatening during diving. The unidirectional rotating bezel prevents accidental operation underwater, further enhancing safety.

The case side at 9 o'clock is equipped with an automatic helium valve that allows any helium that has entered the watch to escape.

When saturation diving, the body must be acclimatized in a decompression chamber using high-pressure gas (oxygen and helium). During this process, any helium gas that may enter the watch is automatically released, preventing damage to the watch case due to a sudden pressure difference between the inside and outside of the case.

The back cover is a screw-down back that protects the movement from water damage.

Unusually for a 500M water-resistant model, the watch features a see-through case back that allows you to see the movement of the mechanical movement through the glass, allowing you to enjoy the beautiful beating of the machine from both the front and back.

The belt is a simple three-link stainless steel belt.

The folding buckle , which makes it easy to put on and take off without dropping the watch, features the brand logo.
