If youre patiant , useing a thin screwdriver ( missuse of tools ) or / & a old thin bone handled round ended knife , like a butter knife , you can reuse it .
Glass can be got from a glass supplyer / cutter . If theyre any good .
To REMOVE , quitely prise a shap pointy thing behind the lip , with the instrument face down on the bench , on some old newspaper - so its flat & dosnt sccratch it .
The scret is to wait till youve got it just behind the lip , J U S T ease it out a IOTA , so the butter knife will get under the lip . Rotate it to circumnavigate the Diameter
so its a slight notch off fastened . The dang bezel should rotate on the case at this stage , or is the first object . Now its F R E E the buter knife is worked around and used to tease the bezel lip out ,
with great patiance & perseverance ,
Youll need to rotate three times , or ten .
The idea is N O T to STRETCH the thin metal . You actually get it way free , but maybe only half as much as right clear , and the butter knife is used to pry it outward ( upward - off ) A G A I N
patiantly . Likely itll chip or total the glass . Not to worry . Banging
the glass out & picking the bits from under the rim gives you more angularity for pryingit off .
Remembering to hold it upside down at this stage , so any schards splinters or chips go into your eye rather than the instrument .
When off , hopefully its evenly prised rather than kinky . You can use the bone handle rolling the bezel on edge on a board with paper so it doesnt scratch , to even it up a way out .
Just enought to get one side over & use the knife or two a bit like a tyre lever , to E A S E it down progressively ( 3 or 4 stages ) so it just P O P S on . Hopefully not stuffing the new glass .
Maybe gettem to cut two . Or flog the out of a old Triumph Herald car - or whatever .
Face down on the bench again , a pice of hardwood about 1/2 wide is used , progressively rotateing numerously to nail the lip to the flange .
If youre having a good day & ate your oats for breakfast , itll be umarked & seal down fimly no problem .
There might be a thin rubber gasket twixt glass & case . Often these are hard dry perished & stuck so therefore disitigrate .
so treat that with caution too , if its survived . a THIN blade edge at rotationally easeing it free from where its at .
