Bulova 10AK US Army WW2 Military Issued Watch

A Bulova Military issued watch commissioned by the Ordinance Department for the US Army in WW2 (#40727) - these watches were robust military issue watches that had to meet comply with US regulations for timekeeping, visibility and practicality.
 
This is a 10AK sub-seconds dial 17 jewel hand wind incabloc movement in a 31mm nickel case issued to the Ordnance Department for the US infantry.
 
This particular example is in good used, working order, it winds and keeps time, but has general age and wear commensurate with age, though the dial and hands are in remarkably good condition.
 
Please be aware that vintage watches, and particularly pre-1950's watches tend to be much smaller than later watches and considerably smaller than contemporary watches - the case is around 31mm and the large crown takes it up to around 34.8mm across, and lug width for the strap is 16mm.
