Patek Philippe early Steel Calatrava
I need help to identify this early Calatrava in Staybrite steel stamped in the case back FB François Borgel the famous case maker of the beginning of the 20th century, normally known for waterproof Calatrava Ref. 565, 437, 1463, pionnier of the water resistance in watchmaking.
The 9" caliber looks in bad condition and is prior to the 12-120PS of the Ref. 96, and engraved the number 13.
Any information will be very useful, thank you.
