From its origins, El Primero defined high-frequency precision at 5Hz or 36,000 vibrations per hour. The CHRONOMASTER Sport Skeleton continues this with the El Primero 3600, measuring 1/10th of a second and offering a 60-hour power reserve. Its tinted sapphire dial reveals the openworked calibre, balancing transparency, structure, and chronometric performance.
