The UR-105 Tantalum Hull

It would seem that this is the end of the line for the UR-105. But if you're gonna go, you might as well go out with a bang -

The UR-105 Kryptonite

The team from URWERK are back with a fun new model, the UR-105 Kryptonite.

And for once, I was very pleased to receive a press release that was not chuck-full of hyperbolic language, but rather told a cool story.  And in this case, I do not feel I could do it more justice than the original, so here it is in their own words -
 
“It’s one of the stories my horologist father told me as a child,” recounts watchmaker Felix Baumgartner the brand’s co-founder. “He was fascinated by the stories associated with the historical timepieces he restored. According to the legend, the Pope ordered a special clock from the Campani brothers. It had to tell the time in the dark when he celebrated the divine offices at night. But the clock had to be silent so as not to disturb the Pope when he slept, while the time had to be immediately visible. The Campani brothers produced the so-called “wandering hour” clock in which the hands were replaced by hour numerals that successively traversed a scale of 60 minutes. The passing hours were illuminated from within the clock by a candle. Needless to say, many of these clocks, made largely of wood, caught fire, and the system fell into disuse, but one survivor was sent to my father for restoration. I found it fascinating.”

Thus one of the fundamental requirements of every URWERK watch is to show the time clearly in the dark. “I enjoy the idea of fulfilling the Pope’s specifications,” says Martin Frei, URWERK’s co-founder and chief designer. “By preserving its original DNA, we have kept the concept alive.”

A great watch, more often than not, has a great story behind it.  And this is clearly one of them.
