Ollech and Wajs M-65 with NATO dial
The watch itself is somewhat diminutive by current standards, less than 37mm without the crown, an even 40mm with the crown, 41mm lug to lug, with an 18mm strap. It’s 11mm thick, but this is partially due to the acrylic crystal, which extends 2.5mm above the bezel. The acrylic seems a little out of character on a modern automatic watch, but this watch is made to a Viet Nam War era specification, and was made as an alternative to the issue and Timex watches available to U.S. soldiers and sold in the PXs in Viet Nam.
