PROMASTER
[A pilot watch with a compact 40mm case size and a metallic sheen] The Citizen PROMASTER is a genuine sports watch that combines functionality, durability, and safety. This compact model features a 40mm case diameter while incorporating an aviation slide rule function. It boasts excellent visibility and operability, as well as a luxurious shine.
[Metallic Luster] The edges of the sub-dials and indices have a mirrored finish that gives them a three-dimensional appearance. The case lugs and crown guard also feature extensive mirrored surfaces, creating a metallic sheen throughout the watch. In addition to the aviation slide rule markings, the 1/5 second chronograph markings are also finely engraved, creating a precision befitting a pilot watch.
