Zenith celebrates Sincere Fine Watches’ 70th anniversary with a titanium Defy Skyline featuring an unprecedented combination of complications
For its Platinum Jubilee Edition timepiece commemorating Sincere Fine Watches’ 70th anniversary, Zenith has chosen the Defy Skyline which features the premiere of a combination of complications never before seen in the series.
The El Primero, one of the world’s most renowned and precise movements in horology, is integrated with a big date and flyback function, a fusion of technical feats that redefines the Defy Skyline range. It is an apt tribute to Sincere Fine Watches’ enduring spirit, as the El Primero has become a symbol of Zenith’s innovative legacy since its debut in 1969.
The flyback function allows the chronograph to be reset to zero and restart with a push of a button. The big date at 6 o’clock features a patented compliant mechanism that enables both date wheels to advance and stabilise in under 0.03 seconds

Limited to 70 pieces, the 42mm the Defy Skyline Big Date Flyback Sincere Platinum Jubilee Edition is sleek in sandblasted grade 5 titanium from case and bezel to the integrated bracelet, emphasising the Defy Skyline’s architectural form. The monochromatic aesthetic is complemented with a metallic grey dial, satin-finished and engraved with a starry pattern inspired by the “double Z” Zenith star logo found in early Defy wristwatches.
The bracelet is fitted with a quick-change mechanism to switch it out for a rubber strap.
