【Wave Tracker with Yacht Timer and Tide Graph—Enhanced Functions Supporting Marine Activities】A professional sports watch with functionality, durability, and safety, Citizen PROMASTER. Since 1985, following the release of the 'Sporty Wind Jack,' Citizen has been producing watches equipped with yacht racing timers.

It also shows sunrise, sunset times, and moon phase, making it useful for surfing, fishing, and other marine activities.
