Zenith Defy Skyline 36 Rose Gold / Silver Ref. 18.9400.670/01.I001

The Zenith Defy Skyline 36 mm 18.9400.670/01.I001 was presented in 2025 as a proposed addition to the Defy Skyline collection, featuring a reduced case diameter and a precious-metal execution. At the time of writing, it remains unclear whether this reference progressed beyond the prototype or design stage into full serial production. The watch is specified with a 36 mm case crafted from 18-carat rose gold, paired with an integrated bracelet in the same material. Water resistance is listed at 100 metres. The case design follows the angular, faceted architecture characteristic of the Defy Skyline line and is fitted with sapphire crystals on both the dial side and case back. The dial is described as silver-coloured and configured with a time-and-date display, including central hours, minutes, seconds, and a date aperture. Applied hour markers and central hands complete the layout. Powering the watch is the automatic Elite 670 calibre. This manufacture movement is specified with a power reserve of approximately 50 hours and supports standard timekeeping and date functions. While the Defy Skyline 36 mm 18.9400.670/01.I001 is documented with full technical specifications and a stated release year of 2025, confirmation of commercial availability or serial production has not been established.
