Replica of popular Hamilton MIL-W-46374 military wristwatch but made with one-piece OD green plastic case. It is powered by 17 jewels manual wind movement supplied by Japanese watch company Citizen.

These type of replica military watches were usually sold at shops just outside military base during the 80s and were popular among Korean soldiers because they were cheap and looked like the real thing.
