My dad was given a Seamaster when he finished working in the 1970s. Would be interested in any information about it please. Markings on the back are: 73 18k 0750 16211' Thanks in advance. Oh he had a gold pocket watch with ALD, an anchor, .375 and the letter D on it. Any recommendations a to where I might find out about that too please. He inherited it from an uncle who died in 1938 I think. Cheers.
Welcome to the forum! Can you include some pictures of the caseback with the numbers that you are referring too. It would allow us to be of better assistance to you. Presumably the 0750 you noted on the caseback is referring to the 18k gold. 16211 might be the reference number although nothing shows up in omegas database but that happens sometimes. The dial appears to have been refinished sometime in the past.
Photos of the back will likely confirm my suspicion that it's a fake Omega. You can find some more info here: Is this Seamaster from the 1960s? | Omega Forums
