Ref. 5441 case and glas diameter

Dear all
I am interested in a ref. 5441 and am reading different information on the case diameter (42 to 43.x mm) and the glas diameter (38 to 40 mm).
Can any of you owners help?
Thanks.
Regards
Steve

Sorry Steve but don't know exactly. I did expect 42 mm, so I'd check some commercial sites for the most often quoted size....

Best,

Bob

I'm sure the case diameter is indeed 42mm like Bob already indicated. For the glass diameter, I am not sure.
