"Patek Philippe collectors consider the reference 1463 vintage chronograph to be among Patek’s
most important watches. Introduced in 1940, this chronograph has a unique profile, owing to the highly domed crystal
and massive screw back. In a family of otherwise dressy Patek chronographs, the 1463 is, well, sporty looking.
While ‘sporty’ and ‘chronograph’ go hand in hand these days, this watch’s relatively massive construction was
revolutionary in its day. The screw back introduced a water and dirt resistance otherwise unknown in the 1940s.
Case is 18k with dimensions of 35mm diameter by 14mm thick. From lug tip to lug tip, this watch
measures 43.2mm. As mentioned, the caseback is threaded and screws down into the center part of the case.
This was Patek’s first chronograph to implement the screw back, so as to achieve increased water resistance.
The case also features a second, internal protective cover for the movement. As you can see in the pictures below,
Patek has stamped “Vacuum” into the inside of the 18k caseback.
