Welcome to classic wristwatch
A USA made Waltham military wristwatch. These watches were used from WW2 through to the war in Vietnam. This is a fully restored example using some reproduction parts. It is in really nice condition.  The watch is fitted with an olive canvas military strap, as it originally would have been.
The white dial has luminous hands and numerals, sub seconds at six and an outer minutes chapter.  It is signed Waltham in black. The watch feature an oversize crown to allow it to be wound whilst wearing gloves. These old US military watches are lovely things to own, and have a unique look when worn.
Dimensions = 16mm between the lugs, 31mm w/o the crown, 35mm with the crown and 39mm lug to lug.
