Urwerk – UR-105M
The new Urwerk UR-105M was considered in view of a protective layer. Like a shield, a steel defensive bezel ensures the titanium body.
The satellite complication is entrancing. There are four satellites, every one of them showing three of the twelve hours. The current hour makes an hour long journey along the minute scale. Once the hour has passed, the satellite turns and proceeds around its circle for an additional three hours prior to returning to the middle stage.
Two extra signs, running seconds and force save, are displayed horizontally working on it band.
This seconds pointer is synchronized with the honeycomb 10 seconds disk on the correct side of the case close to the moment scale.
On the back, we discover the Control Board as Urwerk calls the arrangement of extra signs including oil change (when it is the ideal opportunity for overhauling), the 42-hour power hold and the calibrating screw permitting the change of the rate.
The case, whose measurements are 39.50mm x 53mm x 16.65mm, has been pressure tested to 30 metres. The UR 5.01 manual-winding development beats at 28,800 vibrations each hour.
Two variants of the UR-105M are accessible: the Iron Knight with a titanium case and a steel bezel and the Dark Knight with a titanium case and an AITin-treated steel bezel. AITin is a black multi-layered covering of Aluminum Titanium Nitride delivered by the actual fume affidavit (PVD) measure.
