Rather than reproducing the past, ZENITH has re-engineered the Calibre 135 for the 21st century, preserving its original dimensions, frequency and architecture while integrating modern materials and technical solutions to enhance performance and reliability. Under a sapphire box crystal, the dial reveals a three-part construction: a central bloodstone disc whose natural veining ensures every piece is unique, an oversized mother-of-pearl small seconds at 6 o’clock, and a peripheral guilloché sector inspired by the brick façade of the ZENITH Manufacture in Le Locle.
