Lot essay 

From the very beginning of its activity, Urwerk has developed the design of its wandering hours complication. The inaugural models UR-101 and UR-102, equipped with such a time indicator, were launched in 1997. Development of the UR-103 was carried out over several years, and the first timepieces were presented by the brand in 2003. The UR-103 is widely considered the starting point of the brand’s success. With the UR-103.01, Urwerk gained worldwide fame, at the same time establishing its dominant position in the production of wandering hours complication watches, which have become both synonymous with and a symbol of the brand. Connoisseurs of high watchmaking art and independent watchmakers took to the watch with great enthusiasm, and many still consider it Urwerk’s best design. The UR-103 was finally discontinued in 2010 and the brand began developing a new entry-level model with an alternative design.

The present example is one of only two editions of the UR-105 featuring hand-wound caliber, released as a limited edition of 77 pieces, which certainly adds to the appeal of this lot.

The UR-105M, from a new Urwerk collection and successor to the UR-103, was launched in 2014. The brand introduced two models, the UR-105M ‘Iron Knight’, in stainless steel and blackened titanium (the present reference), and the UR-105M ‘Dark Knight’, in stainless steel with black AITin-coating and blackened titanium, both issued as a limited edition of 77 pieces. 

The watch is powered by the UR 5.01 caliber, a modernised version of the UR 3.03 caliber used as the base for the UR-103 collection. Both are based on the Eta/Peseux 7001 caliber, supplied by La Joux-Perret in a reworked version. The UR 5.01 caliber features an updated version of the control board with oil change indicator and a timing screw with indication window on the caseback to adjust the rate of the watch, as well as a number of additional indications. Among them are seconds and power reserve indicators on the side, which is unusual for Urwerk; an additional power reserve indicator on the caseback; and a digital 10-second indicator, which is situated on the dial side of the watch, between 0 and 5 on the minute scale – part of the time it is hidden under the rotating satellite indicator of the watch. 

The UR-105M ‘Iron Knight’ and ‘Dark Knight’ limited editions represent a very short initial period of development of the UR-105 line with manual winding, with just two references released. All subsequent UR-105 models were equipped with self-winding movements – until the collection was discontinued in 2021. The very rare manual-winding caliber and the strictly limited production makes the present example very attractive for the collector who appreciates the oeuvres of independent watchmakers. 

Reasons to bid 

The Urwerk UR-105M ‘Iron Knight’ Limited Edition would appear to be a fine purchase for the collector thanks to its unique futuristic design and rare wandering hours complication, developed by a world-renowned independent watchmaker. The present example is one of only two editions of the UR-105 featuring a hand-wound caliber, released as a limited edition of 77 pieces, which certainly adds to the appeal of this lot. The collector will perceive the ‘Iron Knight’ watch as a sign of an important and very short stage in the development of Urwerk’s basic collection, associated with the transition from the initial UR-103 purist design to the cool, eye-catching and futuristic UR-105 design that is the mainstream of the brand’s modern collection.
