It would be very lucky indeed to find a gilt dial from the 50's in that condition, I'm not that fortunate!
This reissue was called the "Janeiro" from the mid-90's, and it's a pretty obscure reference which I happened to pick up off eBay quite inexpensively.
Tissot did a pretty decent job with the gilt dial, and even used the old Tissot font. However they put in a date (hmmm....) but at least they took the trouble to add some faux patina to the date, which was a bonus for me. A fun weekend watch!
