Looking for help with a glued watch crystal on my Grovemade watch. The hour hand has fallen off so I'm looking to reattach. I have removed the wood front to discover the crystal is glued (I think) in to the metal rim. There are no further screws and no available 'lip' on the watch to prise the front off (I tried this with a tiny screwdriver but don't want to crack the crystal and as you can see I have started to damage it).
I have read there is either heat or freezing methods to remove the crystal, but the rest of the watch mechanism is still attached. So I'm afraid either heating or freezing would damage the watch permanently.
They're made in the US while I'm in the UK, so replacement parts could be expensive.
Any ideas on a safe way to remove the crystal? help would be much appreciated.
