For the last 20 years, Urwerk has been pushing the boundaries of traditional watchmaking. The market was taken by storm when the firm introduced the revolving satellites with telescopic minute hand extensions to indicate the time. The watch inspired the nickname “Hammerhead” for its unusual case design. “The Twin Turbine” Hammerhead has satellite hours with shock absorption in micro-sandblasted black titanium nitride. This is the world’s first watch with the winding rate regulated by fluid dynamics. There is a patented carousel with a revolving satellite complication with wandering hours and telescopic minutes and hands, a day/night indicator, a moon phase display and a scratch-resistant sapphire crystal with anti-reflective coating. The solid case back is black titanium secured with 4 screws, engraved with “URWERK – EDITION SPECIALE – SWISS – TURBINE AUTOMATIC,” and the twin turbines are visible through sapphire crystal apertures. The shield-shaped 46.6mm by 43.5mm solid two-body case, screwed hinged lugs and beveled trapezoidal bezel are satin titanium. The “windmill-blade” dial is black engine-turned guilloche, yellow SuperlumiNova Arabic hour numerals, and on the bottom of the watch between 8 and 4 o'clock is a luminous yellow minute arch with a skeletonized pointed indicator hand.
The watch is in very good condition. The movement is running at the time of cataloging, however, it was not tested for the accuracy of time or duration of the power reserve and may need service at the buyer's discretion. Please note that Sotheby's does not guarantee the future working of the movement.
