Re: 8110a octagon
Any idea how to replace the crystal?
My 9 year old son and I were messing around and he whacked it with his knuckle. Smashed it.
Watch seems ok. Any advice?
Thanks.
Andrew.
Ps great site!
Hi Andrew, thanks for visiting my blog. What a shame that your crystal got broken. I’m afraid original ones are very difficult to find. The original part number is 54-70600. The glass is pressed into place over a white gasket that sits inside the bezel – the gasket has to be fitted in the correct way. Is yours still in position? If so you should be able to see that it is thinner on the upper edge so the glass can be pressed down against the the lower, thicker edge to get a tight fit. Needs to be done carefully and preferably with a crystal press. If an original crystal can be found, it would come with a new gasket since the old ones can get kinked/damaged when the old glass is removed. If you’ve not dome this before I would recommend going to a good watchmaker – these are valuable (increasingly so) these days so worth minimising the risk of damaging it. Stephen
Thank you!
Ok so the Crystal is pressed in from the top, ( so movement does not need to be removed I guess?). The gasket still seems to be in place. I see some crystals/bezels on eBay, not sure if original or aftermarket parts .. Like this one,
https://www.ebay.co.uk/itm/Mineral-Glass-Crystal-With-Black-Al-Bezel-Citizen-8110-Cal-67-9011-Bullhead/323638335119?hash=item4b5a59168f:g:tYMAAOSwu3ZcMpb5
which has a black bezel (for the “brad Pitt” base metal bullhead) … presumably the crystal could be pushed out of this and installed into mine. But do you know if the crystals are all the same size for the octagon and the base metal bullheads?
Do you know the exact specs/size of the Crystal I need?
Thank you!!
I would advise that the movement is removed when fitting a crystal, just in case something goes wrong. It’s not a difficult task. The eBay crystal would not fit, they are different sizes. I’m afraid I don’t know the measurements, I couldn’t measure it accurately enough either. There is this on eBay: https://www.ebay.co.uk/itm/Mineral-crystal-Fits-Citizen-8110-67-9356-Bullhead-Oktagon-27-/112851203607 No idea how good it is or whether it is sized to fit the gasket, but might be worth trying.Stephen
Thank you so much for the link and all this info !
you’re welcome
Follow up question, (I may have asked this elsewhere on the site, sorry for multiple posts) as you showed me There are some after-market crystals available on eBay
To install, do they simply push straight down into the watch bezel with a crystal press? Does the bezel
Need to be removed for any reason? I believe I saw there is a thin black gasket still in there around the bottom of the inner bezel after I picked all the broken glass out. That just stays there I guess? Is there any procedure to this or is it a simple (careful) push-in?
Thank you!
Hi Andrew, sorry for my late reply. The crystals are pressed in with the bezel still in place. Original crystal gaskets are white though, so it looks like yours is a replacement, so it’s a bit of try it and see what happens I’m afraid with non-original parts. Original crystals came with a new white gasket – do the after market ones also have a gasket? Stephen
No gasket on the aftermarket crystal.
Thanks for the info. I guess I’ll buy one (or two) and try getting it in. I wonder if aftermarket gaskets are available. Hopefully the one still in there will suffice.
Thank you!
You’re welcome – hope you can sort it
It’s a cool watch. I happen to have one in my watch shaker.
Thanks for visiting my blog – great to read that you have one of these 🙂 Stephen
