ZENITH is expanding the DEFY Skyline collection with the world’s first skeleton watch featuring a 1/10th of a second indicator.
A constantly running 1/10th of a second counter at 6 o’clock makes steady jumps in fixed increments, completing one revolution every 10 seconds, a feature that’s unique in watchmaking to the new generation of the El Primero automatic high-frequency calibre.
The open dial comes in black or blue, with the skeleton movement finished in the same colour as the open dials for a cohesive and architectural look. The screw-down crown emblazoned with the star emblem provides a water-resistance of 10 ATM (100 metres).
Visible from the front as well as the sapphire display back is the openworked version of the high-frequency automatic El Primero calibre, the 3620 SK. Built with a similar architecture as the El Primero 3600 1/10th of a second chronograph, this automatic manufacture movement drives the 1/10th of a second hand directly from the escapement, which beats at 5Hz (36’000 VpH), thus making it a “natural” fraction-of-a-second indication. It is also endowed with a stop-second mechanism for precise time-setting. Efficient in its performance, the automatic winding mechanism with bi-directional rotor with a star motif delivers a power reserve of approximately 60 hours.
With versatility at its core, the DEFY Skyline Skeleton comes on a steel bracelet with a satin-brushed surface with chamfered and polished edges, seamlessly flowing with the sharply faceted lines of the case. It also comes with a rubber strap and steel folding buckle with a starry sky pattern in continuity with the dial, made in blue rubber for the blue dial version and black rubber for the black dial. The wearer can easily switch between the steel bracelet and rubber strap without any tools.
