The UR-100 is now Urwerk’s best-selling mannequin and, by Urwerk’s requirements, a no-frills watch that options the model’s signature wandering satellite tv for pc disc for hours and minutes. In different phrases, it serves as a fundamental mannequin and attracts many lovers who dare to strive avant-garde time shows from impartial watchmakers.
For that reason, the UR-100 has undergone a number of iterations to swimsuit the totally different preferences of collectors, providing a spread of supplies and dial colours. Nevertheless, the most recent model introduces one thing new to the show. For the primary time within the vary, the UR-100V Lightspeed includes a illustration of the time it takes for daylight to achieve each planet within the photo voltaic system.
Staying true to its UR-100 roots, the UR-100V Lightspeed maintains the mannequin’s slim physique design – now product of carbon – which is slimmer in comparison with typical Urwerk fashions and ensures wearability for a variety of wrist sizes. As well as, it retains the signature wandering hour and minute operate, consisting of three satellite tv for pc discs positioned hourly on a carousel, every alternating to show the minutes on an arc scale. Whereas less complicated than the model’s satellite tv for pc dice, this show gives an inexpensive glimpse into Urwerk’s distinctive impartial watchmaking fashion.
Nevertheless, the most recent Lightspeed eliminates the twin astronomical show that was current in earlier UR-100 fashions. This operate provides the gap the Earth travels each 20 minutes because it rotates round its axis (roughly 555 km) and the gap the Earth travels each 20 minutes because it orbits the Solar (roughly 35,700 km). . This data was conveyed by the motion of the hand on the touring hour disc, which rotates across the whole dial. Virtually, the cutout is sized in order that the pointer takes precisely 20 minutes to cross by means of it.
Though the twin distance show is being phased out, Urwerk has launched new astronomical data on the dial. The Lightspeed mannequin takes under consideration the time it takes for gentle to journey from the Solar to every planet within the photo voltaic system. This data is obtained by calculating the gap between the Solar and every planet, bearing in mind the velocity of sunshine, which is roughly 299,792.458 meters per second – the quickest velocity attainable within the universe. For instance, it may be decided that on common daylight takes round 8.3 minutes to achieve the earth.
Because the velocity of sunshine is a continuing, usually represented by the image “c” in physics calculations, the time it takes for daylight to achieve every planet stays fixed, with the variation within the distance between the solar and every planet throughout of the circulation cycle is briefly ignored. This data is now displayed on the watch face and represents a set numerical worth somewhat than a dynamic time show. It serves neither as an indicator nor as a complication and suggests much less curiosity than first impression.
Contained in the watch is the UR 12.02, which consists of URwerk’s proprietary module and a Vaucher-made base motion, totally different from earlier actions that have been derived from a Zenith caliber. Nevertheless, the UR 12.02 nonetheless options the “wind catcher” elevator system with a star-shaped wheel on the rotor that makes six revolutions for every rotor revolution, thereby controlling the elevator velocity.
