Welcome and thanks for sharing, that's a beauty! I found it in the 1973-1975 Linebook184 listed as

I believe this is a first for the database.

Great information. I am trying to find a crystal for the watch. The case number is T-3083. I found in the spare part catalog only the GT-3083 reference and the supposed part number is 1222-1. I am not convinced that it is the correct part number. I have measured the outside diameter and it has 29.3mm. Can someone help me to identify the correct part number?

I have measured the crystal without removing it from the case. It seems like is not original. Since the crystal doesn’t have an inner tension ring, it seems like it is secured by the outer steel bezel. Could you confirm that? There is almost no space between the case and bezel to insert a knife of bezel removal tool.  Any ideas of how to remove the bezel?

Thank you very much for the information. It seems like the bracelet is exactly as the Sea King model found in an 1959 advertisement

1975 Accutron Model 21123-5W is a good ID. The bracelet would not have been available in 1959 however as it has an Accutron logo.  Accutron was not introduced until 1960. My guess is that it was added later, maybe even in 1975.
