Preserving its functionality and general layout, the new Ulysse Nardin Sonata Streamline (ref. 675-00) alarm watch features a slightly upgraded automatic movement and an absolutely stunning -though some may call it kitschy- exterior appearance with the satin-finished titanium accented with a glossy ceramic bezel and polished rose gold crowns and push-pieces. Yet, to many of us the most interesting part of this watch is not the color scheme or the combination of materials, but the gorgeous -both in its complexity and finish- Caliber UN-67 self-movement that the Swiss-based brand designed and manufactured at their own production facilities.
With a number of its parts crafted from silicium -a high-tech material that is as lightweight as it is resistant to magnetic fields-, the new Caliber UN-67 is so far one of the most advanced mechanical movements in the world.
Judging by its specs, the UN-67 is an evolution of the UN-66 caliber that powered the 2008 limited edition Sonata Silicium. While the older watch limited the use of the high-tech material, which is usually employed to make electronic components, to its dial and a patented hairspring, this new caliber adds to the mix a silicium-made anchor and escapement wheel thus making the watch even more durable and precise. All these parts are made by Ulysse Nardin’s sister company Sigatec, so the movement still can be called “in-house”.
Packing a truckload of features (like an alarm clock with cathedral bells and a second time zone), the movement is incredibly complex. It uses as many as 109 jewels to run as smooth and as energy-efficient as possible. Still, the watch offers no more than 42 hours of power reserve, so you will possibly have to keep it inside a high-end (and also safecracker-proof) winder.
For such a complex timekeeper, the watch is still quite compact. Compared to the 2008 year model, its titanium body grew only two millimeters wider, now measuring just 44 millimeters in width.
The traditional open-worked rose gold hands with white Superluminova patches on them look easy readable and the pair of blued hands at 10 hours (count-down timer) and 2 hours (alarm setting) are very contrast and, too, easy to read. It is also nice to see that, thanks to the shape of sub-dials and hands, the dial of the watch gives a whole new meaning to the word “face”.
