1.The MIL-W-46374 were primarily intended for non-aviation personnel, Army, Marines, Brown Water Navy. I believe all of these (during that period) were purchased under Army contract.

2. The MIL-W-3818B, primarily aviation, some under Army contract, some under GSA contract.

3. The Hamilton Type 1, might be classed as exclusively aviation, and probably mostly USAF.

4. GG-W-113, anyone that need a watch accurate to at least 30 s/d, mostly this would be aviation, all were purchased under GSA contract.

5. MIL-W-50717, Type I, anyone in need of a dive watch, although most (all but the first batch) seem to have been bought under Navy contract.

6. MIL-W-50717, Type II, similar to above, but all of these were purchased under Army contract.

Some guy at face book posted what he claimed was an AF issued watch from the Vietnam era, a Type one which is a Hamilton. I think he got conned at ebay.
