Stocker & Yale Military Watch
Model Sandy 184A
This is a US Military Watch that dates from the 1980's and was made by Stocker & Yale. The back states...
Watch, Wrist-----General Purpose-----Mil-W-46374D-Type 2-----Stocker & Yale - 90640 Code
NSN 8645-00-952-3767-----Model Sandy 184A-----Swiss Made.
The best part is, it says to dispose of as Radioactive Waste. I'll assume it has a Tritium dial. No hack feature. Green nylon strap. I bought this new around 1986.
