    Replace Bremont crystal or remove AR coating?

    I've got a first-world dilemma: picked up a Bremont U2 recently with a well-worn crystal. It's got a number of small marks (no big deal), but one large blurry area of wear that consumes a good portion of the right side of the crystal - and this large blurry area is detracting from my enjoyment of the watch. Part of me enjoys the peace of mind that comes from not having to worry about beating the watch up, since the case and crystal, etc. are already well worn - but the other part of me badly wants to be able to glance at my wrist and see the dial as Lord Bremont intended.

    Sending it back to NYC Bremont is an option, but I'm assuming it's an expensive option that may keep the watch off my wrist for almost a month. Has anyone considered (or attempted) to remove the outer AR coating on a Bremont? This would be an interesting (and cheaper/quicker) alternative; however, my understanding is that the AR coating is applied in multiple layers and significantly hardened to (in theory) be difficult to scratch, etc. So I'm wondering if AR removal is even a feasible option.

    Thoughts? What would you do/recommend?

    Thanks! Apologies if this has been discussed previously in another post.

    There’s no external AR. The marks are metal deposits from dings against metal. Use some chrome polish and some elbow grease and it will be like new again. Be careful not to get polish on the bezel as you might accidentally polish that!!

    I like that answer! - and have some Mothers mag and aluminum polish. Might that do the trick?

    Give it a go, can’t do any harm. I use Solvol Autosol. It takes a bit of effort though but it will come off.

    Great tips! I, too, have a small blemish on the crystal. It looks like chipped coating, will get some metal polish and try.

    It took a number of polishes (maybe 20 minutes worth of effort), but it really worked well. :)

    I never deny a picture request! The prior owner must have a story or two to tell... some honest wear on it. ;) the scratches that bothered me used to be in upper right quadrant on the crystal. Now that they're gone, I notice I've got more work to do on the rest of the crystal...
