Rolex 6066 replacement crystal

Gave my wife a vintage Rolex recently which she has dropped and cracked the crystal. I cannot for the life of me find the reference for the replacement - and I have searched online!
Can anyone help here, or can source one for me? I am in the UK.

its a 1954 model, untouched since new!

I have a guide at home and I will check if it has this reference. I return on Wednesday, will let you know either way..
Very nice looking watch! You dont see many of these..
I did a little research and this model came with and without the cyclops, even though it has a date..
Cheers..

Came across a thread on WUS on a member looking for parts for this particular watch. Link below, dont know if you have seen it.
Looks like he did some measurements and lists the size of the crystal as 25.27mm.

I will still check my reference guide..

Here you go. Second line up from the bottom. 25.4 is the answer, found it on my reference guide. I called my watchmaker with a Rolex parts account and he said it would be referred to as 25dot4. He did not have it listed on his reference guide. If you find a watchmaker on your side of the pond, they would have to call Rolex to get the proper reference number to order since the watch is so old, if you decide to go route.
Don't know if you have tried but I have heard great things about Superlative Time in West London.
Good luck and hope you are able to get it fixed soon..
