I have 4 Lord Elgin 'Aquamaster' watches from the late 1960s. They all have the same crystal - 32 mm armored, flat top. Two, I can live with. One has been replaced with a domed crystal that is too small and tries to fall out, and one is scratched all to hell and gone. Trying to be self reliant, I depended on the pictures in the G-S catalog, and bought a 'ThinTite' crystal - armored, low profile, flat top. Turns out the profile is TOO low, and they stop the second hand. Okay, so not that. So then I tried a 'AngleTite' crystal - too tall. Sits WAY high. Also the beveled edge is distracting. Not right. Here's what it looks like from the side: And here's how tall the profile is - 2.5mm I figure 1mm thick, with a 1.5mm skirt. This one WAS armored, but I lost the ring. The opening measure 32mm. Any ideas?
