MACV-SOG Era March 1968 Seiko 6106-8100 Diver w/ Waltham W.C.Co. Military Compass

Offered here is a beautiful and historically significant March 1968 Seiko 6106-8100 diver, a model widely associated with MACV-SOG personnel during the Vietnam War.

This example remains in honest, unpolished condition, retaining its original case lines and character. The watch presents extremely well and is running strong, having been professionally serviced by Rexworthy Watches (UK)—a respected name in vintage Seiko restoration.

The watch is paired with a period-correct Vietnam-era U.S. military-issued strap, complete with a Waltham W.C.Co. military compass. The compass is fully functional, though the crystal shows some surface crazing consistent with age. It does not detract from usability and adds to the authentic field-worn aesthetic.

These watches have become increasingly collectible due to their documented use among elite units such as MACV-SOG. For deeper historical context, I recommend researching DC Vintage Watches, which has done extensive work documenting these models and their connection to U.S. Special Forces in Vietnam.
