I am not sure of the year or model.
Just gave the movement a full clean and service, replaced all neccessary(broken) parts, pulled case apart cleaned and re-set crystal .I believe it is 100% original.
The crown ?

Nice HE NN. By 1949 does the first digit of case SN relating to production year still hold? I think we had some examples where we it did, but don't remember why that relationship was weaker that year. Maybe we had some models which we determined by ads were 1949, but their case SN's started with something other than a "9"?
Wish I had time to be here more often!

Perhaps these cases were made in more than one location, because some of these can be seen with a 6 or 7 digit case s/n. We see a '48' stamp on some, but looking through the database too many of these examples have no photo of the caseback, so a bit hard to find similarities. I would agree with 1949 based on the first digit of s/n.
1949 His Excellency 'NN'
The crown does not appear original to this watch.
