  1. What is this foggy patch on my Nomos? a scratch or fog?

    Public Forum
    Hi WUS just noticed this today there is a circular foggy patch in the centre of the crystal on my Nomos. I haven't bumped my watch against anything with any large force recently and have not scraped it on anything so I am quite confused as to how it got there and what is actually is. Could it...
  2. Timex "UFO" Crystal removal

    Hi, Brand new hobbyist here--I bought a set of tools to work on an iPad and decided what the hey, while I'm working on small things, why not fiddle around with a few old mechanical watches I had lying around that didn't work... Of course, I got hooked and bought more tools and more watches and...
  3. SKX013 top hat crystal causes bezel issue

    Has anybody run into this? I installed a sapphire top hat crystal in my SKX013, and now the bezel is extremely hard to turn. I hate to switch back to the original crystal, but I use the timing bezel often and it should be functional. I really like the look of the new crystal and want to make...

    Casio G-Shock
    Has anyone actually done this and if so are there any guides/tips? I have searched but I cannot find any videos out there as of yet. I am tempted to buy a bit of a beat-up PRW-3000 to use as a test piece to disassemble and see how everything comes apart. I have a watch shop locally that will...

  8. New Seamaster 300m Crystal not level / uneven?

    I just acquired this watch last week, and while I love it, it seems the crystal is not set level. I could just be OCD over it, but there is just a hair difference (0.5mm) rise on the right side versus the left. It's not really visible, more so just felt. I have found extreme cases of this to...

    I need to replace a cracked crystal on an early 1960's Seikomatic - the part number is 338W01AN, but when I look at NOS crystals on ebay, I'm finding a lot of 338W01AN0 and 338W01AN00 crystals. Can anyone tell me if there is difference between the three? I'd normally just have my watchmaker...

    Hello - Where is the proper place to buy a replacement crystal for an old (70s/80s) Seiko 6309-7049? Are all Ebay sellers created equal, or are all crystals just fine? Or are some unreliable pieces of glass and I need to watch out? Pardon the basic question. I'm starting the process of...

  13. Does anyone know how to replace the crystal on the Casio GWM850-1 watch?

    Casio G-Shock
    Hi, I need to replace the crystal on my Casio GWM850-1 G-shock watch. When I disassembled the watch, I took out the movement and what was left inside the case is what I think is the "solar plate" that has the labels (such as Multi Band 6) and the crystal. The "solar plate" seems to be fixed in...

    Was taking some close ups of the watch when I noticed a small spec beneath the 3-mark. I've owned the watch for 3-4 weeks or so now and never looked close enough to realize it was there but now that I know it exists I can't help but stare at it every time I look down to tell the time. I'm...

    Does anyone have experience using the inexpensive types of crystal lifts found on Amazon or eBay? These sell from $10 to $20. Do they work at all or is buying on a waste of money? Thanks
