Here is a Chelsea US Army message center clock model M2. Clock case is Bakelite mounted in the original Oak box. Matching serial numbers on the box and movement place # 625350 at around 1959. Leather strap is attached to only one clasp. Second hand is a bit bent but works and clock keeps very good time. Chelsea key is included. Outside box has scratches, writing and tape. Overall condition of the clock is very good. Clock is in original working order and keeps very good time. It is in original and found condition and probably needs routine service because of it's age. No refund accepted and that is why I've started this out low with no reserve.
