Design

Case and Dial
The watch features a rectangular 18k yellow gold case measuring 30 x 23 mm. The case design is characterized by its slim profile, aligning with the 'Extra-Plate' designation of the model. The winding crown is fitted with a blue cabochon, a consistent design feature for the model as stated in the source. The white dial displays painted black Roman numerals and a railroad-style minute track. Notably, the dial lacks a 'PARIS' signature, a condition the auction description indicates is accurate for the mid-1960s production era. Blued hands indicate the hours and minutes.
