A highly attractive timepiece, the present reference 1463 features a fascinating dial, graduated for 5 respirations. With a case retaining strong proportions and retaining crisp hallmarks, the wristwatch is extremely charismatic and offered with a superb 18K pink gold Patek Philippe bracelet with Gay Frères deployant clasp.

Among the most noble and iconic references from Patek Philippe, the reference 1463 is the only vintage Patek Philippe chronograph model with screw back case and round pushers. Launched in 1940 and remaining in production until 1965, around 740 pieces were made in total in yellow gold, pink gold and stainless steel, an average of only 21 watches were produced per year.
The striking pink gold version is the rarest of all, a total of 145 pieces were ever made with only 55 examples identified publicly today. To put this into perspective, 190 pieces were made in steel with 90 publicly known today and 405 in yellow gold with 165 known to survive.

Of particular interest, collectors will notice the chronograph features a dial usually seen on later examples of the reference. Following in-depth research, study leads to believe the present dial was fitted on the timepiece during its lifetime, possibly during servicing. The Asthmometer scale was designed to assist doctors who had an interest in watchmaking. Also considered as part of the medical scales, it was created to assist in measuring breathing, by indicating the number of breaths per minute. Of great rarity, the presence of this scale dial and the overall quality of the timepiece elevates the rarity of the wristwatch, making it a highly interesting specimen for collectors.
