Offered in a limited edition of 8 pieces, the new Urwerk watch is rendered in AlTiN steel with titanium elements. AlTiN, that is Aluminium Titanium Nitride, is an industrial surface coating, originally created to reduce the wear of machine cutting tools. With its increased oxidation resistance and hardness as well as semi-matte black color, this material happens to be an ideal high-tech treatment for the model in question.
The measurements of the case are 106mm x 62mm x 23mm. It is submersible to 3 ATM. Both front and back sides of the timepiece are fitted with sapphire crystals with anti-reflective coating.
Beneath the top glass there is a dial, adorned with a Clous de Paris guilloche motif. It offers a revolving satellite hour complication. The device includes a rotating central carrousel supporting three hour satellites. Each cubic satellite is marked with four hour numbers on their four faces. As the sand-blasted carrousel turns, the satellites revolve on their vertical axis so that their top number has the new hour ready to replace the old.
The dial also ensures three-handed indication of running seconds as well as that of retrograde minutes. The latter are shown by a hand, fixed to a sprung ring around the circumference of the satellite complication. Another function, provided by the new Urwerk UR-1001 Zeit Device watch is a revolving satellite calendar with months and dates. Entirely developed in the brand’s workshops, the calendar automatically adjusts the last date of the month according to whether it has 30 or 31 days.
Moreover, the dial offers Day/Night and Power Reserve indicators, embellished with Cotes de Geneve patterns. The day/night display is filled with black Superluminova for night, white brushed-ruthenium for day and mix for dusk/dawn. The power reserve indicator is endowed with a red low-power zone.
The back side of the timepiece also proposes a set of functions. The “Oil change” indicator informs the user when the service is due - in 3-year time the dial changes from white to red. The running-time indicators for 100 and even 1000 years keep track of the total running time of the movement. Both dials and satellite complications are PE-CVD and DLC-treated.
The timekeeping instrument is powered by a UR-10.01caliber. It incorporates a unidirectional winding rotor. Integrated within the movement are also main and base plates - circular-grained, graced with Cotes de Geneve pattern and DLC-treated. Paved with 51 jewels, the caliber runs at the rate of 28,800 vibrations per hour and supplies a 39-hour power reserve.
The new Urwerk watch is worn on a chain, composed of hand-made, heat-blackened steel links. It terminates in the brand’s bespoke clasp with carbineer closure.
