"The only easy day was yesterday"

Officially commissioned on Jan. 1, 1962, U.S. Navy SEALs saw their
first combat action in Vietnam. They operated in the area of the
Mekong Delta, conducting search-and-destroy, recon  and rescue
missions. SEAL Teams 1 and 2 lost 45 men in Vietnam.

The Benrus Type II Class A is one of just a very few types of dive watches issued
during the Vietnam War to Navy Seals, UDT Divers, and Special Forces personnel. Its
distinguishing feature is its front-loading, asymmetrical case with solid, non-removable
lug bars for strap attachment. Class A is the highest military grade classification a
watch can be given.

Commonly referred to as a one-piece design, the Types I/II cases are in fact a
two-piece design. The case back is press fit in a manner meant to be permanent. The
movement is serviced through the front of the watch case by removing the bezel and
crystal. This front loading style makes necessary the use of a two-piece winding stem,
considered by some to be this watch's weak link.
