Patek Philippe Reference 3445 was launched almost a decade after the legendary Calatrava reference 2526, and its caliber 27-460M offers the same exquisite finishing as the 12-600 AT movement in the 2526. Patek's first Automatic Patek with a Date Feature. Patek kept all of the stylistic characteristics of a dress watch, which explains the elegant look of the 3445. With this reference, the crown is recessed into the yellow-gold case, further adding to the elegance of the watch. Similarly, the thin and long indexes bring an outstanding balance to the sunburst dial. The thin profile of the case and the smaller 19mm lugs make the 35mm size of this watch feel very current, despite production of this model stopping in 1981. Own this classic today!
