The Zenith Defy Skyline model 30.9300.3620/74.I001 showcases a stunning yellow gold setup, characteristic of the Defy Skyline series. This timepiece features an 18-carat yellow gold octagonal case measuring 41 mm, complete with a faceted bezel and a waterproof rating of up to 100 meters. Its dial captivates with an olive green hue, enhanced by a sunray finish and the signature starry-sky design from Zenith. The watch displays time through applied hour markers and central hands, while a subdial positioned at 9 o'clock tracks tenths of a second. At its heart, the El Primero 3620 automatic caliber powers this watch, functioning at a frequency of 36,000 vibrations per hour (5 Hz) with bi-directional automatic winding and an impressive power reserve of around 60 hours. This movement controls the hours, minutes, and the continuously active 1/10th-of-a-second indicator. Additionally, the watch comes with a matching integrated 18-carat yellow gold bracelet and a secondary black rubber strap featuring a patterned design, both designed for easy interchangeability thanks to Zenith's quick strap-change mechanism.
