This reference was launched in 1944 and, with its 41 x 25 mm case and, more importantly, its 'pyramid' crystal, represents one of the finest designs ever created by Patek Philippe, featuring a bold, clean design that foreshadows a mid-century aesthetic. Available in a variety of materials, this piece with its flared 18k rose gold case and two-tone silvered dial is an absolute beauty. The case, dial, and movement are signed. It has been preserved in excellent condition and currently working.
