Sinn Offers its 917 GR Rally Chronograph

Sep 10, 2009
Last month, the German watch-making house Sinn unveiled its novel watch, the 917 GR Rally Chronograph.

This model exposes a countdown bezel, governed by the crown, located at 4 o’clock. Such construction enables the watch wearer to read off finish times with the fractional-second precision. The red numerals accentuate the most important final 15 seconds.

The 44mm case is rendered in fully polished stainless steel. Both front and backsides of the watch are fitted with anti-reflective sapphire crystals. The case-back crystal has the inside anti-reflective coating, while the dial crystal features an anti-reflective compound, applied on both interior and exterior surfaces. The Sinn manufacturer uses its Ar dehumidifying technology to protect the watch case from fogging.

The upper counter indicates chronograph hours, whereas the lower counter, located at 6 o'clock position reveals chronograph minutes. The central seconds hand shows chronograph seconds.

The counter, placed at 3 o'clock, serves to reveal small seconds. At 9 o’clock position there is a display, demonstrating the power reserve level.

The date can be seen through the aperture at 4 o’clock and it is adjusted by means of the crown, located at 9 o’clock.

The 917 GR Rally Chronograph is animated by a somewhat modified Valjoux 7750 mechanical movement. Both shock and anti-magnetic, the Sinn watch offers 100-meter water-resistance.
