The reference 3969R was created to commemorate Patek Philippe's 150th anniversary. Only 450 pieces were produced in 18K pink gold, along with 50 in platinum, making this model a rare find in the Patek Philippe collection. The watch features a digital hour display at the 12 o'clock position that "jumps" from hour to hour as the minute hand rotates around the dial. It is powered by a manual wind caliber 215 HG, where "HG" denotes the jump hour complication. The base caliber 215 was first introduced in 1975 within an Ellipse model and continues to be used in Patek Philippe's current production.
