WWII 1940 Pattern American Army Ordnance / ORD Watch (Hand Wound Mechanical Version)SKU: ORD1 HW In WWII, Ordnance watches were made for the US military by Waltham, Hamilton, Bulova, and Elgin. The original watches were made of nickel plated brass because wartime conditions precluded the use of stainless steel. Consequently, the original watches were not very durable, making it challenging to find one in good condition today. The original watches were very small, measuring 33 34mm, but we have increased the size slightly to 36. 5 mm
