Model themed after the Japan Maritime Self-Defense Force's Mine WarFare Force, which specializes in mine warfare and amphibious operations.
Mine WarFare Force has a history of being dispatched abroad for the first international contribution by the Self-Defense Forces in 1991, following the Gulf War, for mine clearance operations in the Persian Gulf.

This model features a 200-meter water resistance that complies with the ISO 6425 diving water resistance standards. In addition, it incorporates a Day-Date calendar function that reflects the real sentiment of the personnel – "losing track of days when at sea".
Furthermore, this diver's watch is equipped with an internal rotating compass that allows for determining direction using the time and position of the sun, even in featureless open waters.

The case is coated with a matte black PVD finish and features highly visible dot indices. The strap, a longer and water-resistant rubber band, is designed for wearing over wetsuits during underwater missions, taking into consideration the potential for water exposure and ease of cleaning.
At the 9 o'clock position, the emblem of the Mine Warfare Force is depicted with a triple-headed dragon design.
The triple-headed dragon carries two symbolic meanings: firstly, representing the "integration" of the "three" branches of the Self-Defense Forces – the Ground, Maritime, and Air Self-Defense Forces; and secondly, signifying the "three" aspects of the "battles" undertaken by the Mine Warfare Force – amphibious warfare, mine warfare, and challenges.
The back case features the engraved emblem of the Amphibious Warfare and Mine Warfare Tactical Support Unit "AMWC," which is a part of the Mine Warfare Force and was newly established in 2020 under the Mine Warfare Group.
Officially registered product of the Defense Ministry Mutual Aid Association Headquarters.
