Hi,My name is***** have been dealing in and appraising Antiques for over 40 years, and I can help you with this. This is a military watch used in WWII by British and Australian Soldiers, these were made with several different watches. Omega is one the most desireable. The GSTP stands for general service trade pattern. Assuming your watch is in good running condition, it would sell for $200-400 at auction.
