[Citizen] Watch Promaster Mechanical Watch 20 ATM Water Resistant SKY Series NB6045-51H Men's Black

[Citizen PROMASTER, an authentic sports watch that combines functionality, durability, and safety] Equipped with a high-spec mechanical movement equipped with a GMT function. This is a classic mechanical watch with a classic design with 24-hour notation on the bezel, and an authentic mechanical watch whose hour hand moves with the operation of the crown. [Classic design with 24-hour notation on the bezel] A gorgeous finish with a mirror finish on part of the case and band that uses a lot of hair lines. The lugs that connect the case and band are inspired by the aerofoils of airplanes flying lightly through the sky. The back cover is engraved with an aviation helmet as a symbol of a tool pilots can wear with peace of mind. [Authentic pilot's watch] Thick and strong hour and minute hands and 24-hour hands with excellent visibility, an index design inherited from the past SKY series, and a uniquely rounded bezel shape, each part is combined in a well-balanced manner to highlight the GMT function. A screw-lock crown is used at the 3 o'clock position to increase robustness. In addition, an aviation slide rule function that comes in handy in the unlikely event of instrument trouble is placed on the rotating endpaper ring to improve operability. [Mechanical self-winding watch] A mechanical self-winding watch powered by a mainspring. When you wear a watch on your wrist, the movement of your arm moves the rotating weight inside the watch, automatically winding the mainspring. You can also wind the mainspring by hand. (You can also check the operating instructions from the instruction manual on the manufacturer's website.)
