Sinn Instrument Chronographs | Column Wheel Chronograph | 910.020

The 910 SRS is a particularly stylish watch characterised by sophisticated horological details. The time on this watch is stopped by a traditional column wheel chronograph. The column wheel chronograph is a complication of sophisticated craftsmanship, with a tradition dating back to the mid 1900s when the column wheel control mechanism was a key component in traditional chronographs. Such a complication is extremely complex to produce and requires the utmost care and precision in assembly. Since the column wheel controls the start, stop and reset functions, it is subject to high levels of stress..
