Another sapphire glass replacement question

[LittleWatchShop]

I hope I don't irritate the forum by continuing to ask questions about crystal replacements.

I replaced the battery in this watch for my neighbor and offered to replace the crystal.

This looks like the others I have done but I still wanted to ask of there is anything special about these monster watches?

This is an Andrew Marc fashion watch (for lack of a better term).  Seems to measure 33.5mm which is consistent with the 0.5mm resolution for fashion watches (learned from this forum).

I think it's better if you add photos of the watch also the old glass if you have it.

If there is something special about these, I think that is seen only by the people that buys them. Their wholesale cost can be €10 - 15 but inevitably the tag price is easily 10 times as much.

With a Miyota FS2x it can't cost what I wrote before, to be honest I have seen better looking watches build around the same module.

It is indeed a Miyota but cal. OS10  Saw one on ebay for about $40

I am going to just use mineral glass because that is what it has now...save money...easier to recover from mistakes.

I Don’t think there is anything special in theses other than size.  Before removing the crystal , cover it with clear tape “ sellotape” just in case it cracks on removal, measure the case and the old crystal and proceed as normal.

As for asking questions, that’s what its all about. Better to ask than cock it up.   Cheers

Dang...I should have thought of that.  I have busted three of the four I have done upon removal and as a result was not able to measure the actual crystal.  This will be my method going forward.

BTW, I use my BB crystal press to remove (and install) crystals.  I seem to recall seeing someone tapping them out with a hammer (robber <rubber> or some other soft material).

Oh, the big one. Hard to tell from just a front picture.

I recall one one guy boasting to be using a garage vise for crystals. If that makes them proud to have saved the money for a meal or two at Mac Donald's, then I'm happy for them.

Proud of the system my Dad left me.  I have added extra fixtures that I 3D printed.

Finally got around to this.  Here is a pictorial. 

I first taped the crystal with Kapton tape because the stuff seems to not stretch.  Once I put it on, I trimmed around the crystal so that the tape would not touch the bottom fixture.  I had already printed the upper fixture that perfectly fit inside the case.  Both fixtures were 3D printed.

Then one swift squeeze and voila.  There was a little bit that chipped off.

I had already ordered a crystal that was the correct diameter.  However, I was off on the thickness by 1mm, so will have to order again.

@LittleWatchShopSo that's what that funky shaped bit is used for on the press! I've not seen that on any of the replacement tutorial videos anywhere. Got it with my press but didn't have a clue what it was for lol (pic 4).

great question. i print these on my 3D printer. Very handy.
