# Hatsuwo Watch This watch is a reproduction of the MARK 11 used by the British Army during World War II. The mark at the 12 o'clock position is the broad arrow, a symbol of British military procurement, and the mark at the 6 o'clock position indicates that tritium was used for the luminous material. Equipped with a Seiko VH31 movement, the second hand moves smoothly like a mechanical watch. It is fitted with a bamboo-type bracelet that was actually used by British Army pilots. It could be quickly put on even over a flight suit, and was popular with pilots at the time because it was breathable and didn't get stuffy even when sweating. The size is adjustable without steps. Seiko VH31 movement Case diameter: approx. 36mm Lug width: approx. 20mm Recommended for those who like American casual and military styles, such as Hamilton, Khaki Field, Marathon, Naval Watch, MWC, CWC, and MWT.
