It will probably need pressing out from the inside with a crystal press.

Something like a Robur press and dies

Sometimes It's best to use the aluminium dies rather than the felt covered bakelite ones, as the top dies are more for using with acrylic crystals, but I have used them on flat mineral glass when pressing out of and into a case

As Nucejoe says It will have a split stem  once removed a sryinge is used to pump air in via the stem hole, this will blow out the crystal under pressure so make sure the watch is covered, attached is the Bergeon pump but a normal syringe (Ink Cartridge refill) and a piece of plastic to make the seal around the stem tube can suffice.

Hi  I too fail to comprehend, as the stem has no control over the bezel or glass, I can understand if it was a loose  fit and manhandling the watch to remove the split stem you have managed to dislodge the bezel,  I should check carefully when reassembling the bezel and case that the bezel is tight.

    • If frank says these bombè jewels are for balances and similar pivots then they are used cupped side facing the pivot and then capped i assume. In Nicklesilver's reply i guess that cup can also be reversed and used as an oil reservoir leaving the shoulder riding on a less frictioned domed surface. 🤷‍♂️ Hence the use of them on wheels closer to the escapement that have less torque requiring efforts to reduce friction and are also uncapped.
    • Looks that way, if it had any amount of significant jewel count it would say so on the dial.    Looks that way, if it had any amount of significant jewel count it would say so on the dial.  Same answer as Mike regarding the dial, its often just a slapped on name of a retailer but i thought you were way above this understanding Pete ?
    • Light naptha is what you need to be looking for. The carbon to hydrogen ratio is high with heavy naptha, it doesn't evaporate as well as light naptha and is prone to leaving more residue. Try tom's suggestion of the mirror test.
    • Its a big item Michael and a lot that could go wrong with the process of getting it to its new location. I once helped install one of these units into a conservatory that i had built. It was big and bloody heavy and took six of us to get it in safely. If you have sliding doors and you need to remove the whole frame then that may or may not go well. But i would advise getting a professional in if you have little knowledge on the installation of them. The glazing of the doors could well be 6mm laminated glass which again will be heavy very heavy if the glazing units are big. The glass would also need to be set up and packed correctly to open the doors properly more so if they are unframed and the sliders are upvc. Seems a shame but if no one is biting and that may be due to having no warranty i guess the only takers might be someone that installs them for a living and knows how to repair. If its fibreglass just be careful, i sometimes have to cut fibreglass baths out and they are nasty to work with . Thick gloves are definitely recommended,  not fun picking out fibreglass spells two days later that have started to go septic. Good luck with it all matey.
    • I don’t know anything about this product, however assuming you have it if you put a drop on a mirror or piece of glass lying flat on a table and leave it to evaporate if it leaves any sort of residue it is not really suitable for watch part cleaning.   Tom
