I have vintage Men's Hamilton Masterpiece Cal. 760. Similar to this
the screen crystal is in a very rough shape and I want to replace it. Do you know where can I find the replacement or what is is it called? I have googled but no luck. I found this page from esslinger but I am not sure if any of these are good fit.
do you know which one could be a right fit? (if any)?
Thanks in advance
