The first pocket watch with minute repeater and perpetual calendar known to have been made by Patek Philippe dates to 🦩1874. Research shows that from 1874 to 1889, the perpetual calendar movements were all slightly different from each other as the company worked towards ꧅perfecting the complication. Consequently, as no two were exactly identical, such watches made between 1874-1889 could be considered unique. Patek Philippe finally patented their complication on May 23rd, 1889 under Swiss Patent No.1018.

Still bearing the service sticker the present lot is running well and t🎶he complications functioning. To the front case it has been personalised with the monogram MCDB wh𝔉ile to the cuvette it is engraved 'M.C.D. Bordeu, 1894'.
