Hello everyone. I'm hoping someone here can help me source a crystal / lens for an old Timex Camper T41711. This isn't the old old mechanical one, but it's also not an Expedition version. It has a battery, not a mechanical wind. The day code is M9, which comes back to 2004, which is when I purchased it. It may cost more to repair it than it's worth, but it does have sentimental value. I purchased it right out of basic training, and I've had it for over 20 years now and the lens just fell out and I'm hoping it can be repaired. I pretty much wore it 75% of the time since I got it, and it's been with me through thick and thim and deployments. Any help is much appreciated. Thanks in advance. -
Image copied from the link above.. Although I do like the image in the pictures farther up above because it looks more like a snake than it does in the picture down below. Then in the link below is an interesting story.. https://chronopedia.club/Sindaco -

These Bulova's will often have a tension ring with a step or cutout where the dial will fit, just in case you are going to try a 3rd party crystal, so be sure and check that. That dial looks somewhat similar to the 1979 Oceanographer '12503', but without the 'Day'. A lot of the '666' Bulova's were Oceanographers or Snorkels. I've been keeping a database of pre-1980's Bulova crystals and it has two 30.2mm armored crystals; 1404AW (Oceanographer 'C' - link has a good photo of the crystal profile) - which I have a note saying that there is a GS crystal PA462-19D, and the 762AW. I think all three of those are currently on ebay, but if the tension ring is stepped it may be an issue. I've had mixed success swapping an existing stepped tension ring into a correct sized crystal that came with a flat tension ring.
