Patek Philippe accentuates the vintage spirit of this model much appreciated by devotees of fine mechanical horology by equipping it with an opaline rose-gilded dial. The legibility of the dial by day or night is ensured by applied Arabic numerals and syringe-type hours/minutes hands made of gold with an anthracite treatment and white luminescent coating, complemented by a small seconds display at 9 o’clock. The CH 29-535 PS chronograph caliber is distinguished by its architecture protected by six patented innovations, including optimized toothing profile, precision adjustment of engagement depth and self-regulating zero-resetting hammers. This movement also features several distinctive technical characteristics reflecting the same concern for functionality and performance. Its aesthetic and its meticulous finishes are visible through the transparent sapphire crystal case back.
