Movement Serial No.:
Case Serial No.:
This is what appears to be to 1965 Surf King possibly variant GY. It has a stainless case with a snap back caseback. The caseback has a M4 date code but the 11AL 17J movement has a "65" date code. Based on the movement code and the ad match I believe this is a 65. The dial is linen and in excellent condition. Its running great after my initial service where I messed up the hairspring. Somehow I was able to get it back in alignment. I threw it on the only strap I had left. I guess it will do.
