Last week while taking pictures of my Marinemaster, I discovered that the crown is a bit hard to turn. The watch was bought in 2003 and it’s high time to re-apply grease on the screw tracks.
Last Saturday, I brought it to the watchmaker and when I reached there, he was working on a vintage Rolex Submariner that a customer sent in for repair. The model number was 1680 and movement number 1575. This particular model was launched in 1966 with the addition of the date feature to the Submariner range. This specimen he was working on belongs to the earlier batches because the "Submariner" word was printed in red. From 1974 to 1980, the "Submariner" word was gradually changed to white.
I sound like an expert? No… I read from the book.
I also had the opportunity to handle this Omega military watch. It is a nice watch but quite small.
After playing with these watches, I took out the Marinemaster to have the grease applied. Now the crown is smooth as new, thanks to this:
