These watches were manufactured for military purposes, especially for the US Army during the Gulf War (Desert Storm) in the early 1990s. The most important aspect of these products is that there is no sustain for the assembly of the leather bracelet. This section is made entirely of a thick shaft and is completely pure steel. The crown of real Desert Storm watches does not protrude outside the case. It is very important to distinguish between mass-produced products for commercial purposes and rare products of this type. The product you are reviewing was manufactured in 1990. Since it has been professionally restored and FULLY MAINTENANCED (the movement has been completely disassembled, the parts have been cleaned, oiled and adjusted to taste), your watch will work without any surprises. (It does not require maintenance for 3 years unless exposed to direct water or high humidity for a long time.) Product Status: Tested, fully functional.
