Hi guys - looking for a little help if possible.

My dad has worn a Les Must Cartier Tank for about 40 years, that looks like this https://www.pinterest.co.uk/pin/436427020117158784/

For his 70th I had it rebuilt and plated etc... looked lovely. Unfortunately he cracked the glass, so I nee dto try to find someone to replace the glass (for a reasonable price). Unfortunately he had a heart attack and has been in intensive care for almost 3 months, and I really wanted to get this done for him for when he (eventually) comes out the hospital.

I am based in Surrey - does anyone know where I may be able to get this sorted (given covid shutdowns) for a cost that isnt ridiculous.. i was thinking it should really be £150-250ish?

Really do appreciate if anyone can point me in the right direction.
Thanks all
