Sinn is now officially 55 years old, and to celebrate this milestone the company is releasing three limited edition Jubilaeum (Anniversary) watches including this new Sinn 910 Anniversary Split-Seconds Chronograph. This is a very special split-seconds chronograph and is limited to only 300 pieces. A split-seconds chronograph is a complication featuring two chronograph hands, which when started move in perfect alignment appearing as one. A special pusher at 8 activates the split-seconds function, causing one chronograph hand to stop (to measure the timing of an event) while the second chronograph hand continues to run.
When this pusher is pressed a second time, the hands “catch up” and continue in perfect alignment until either reset or separated again. The idea behind this complication, which was invented in the 19th century, is to time events within events, hence the use of two chronograph hands.
While production is extremely complex, the utmost care and precision is required in assembly. Since the ratchet wheel controls the start, stop and reset functions, it is subject to high levels of stress. The highest possible resistance to wear and tear is required in order to make full use of the benefits, for example an easy-to-operate push-piece.
The workings of the perfectly synchronised mechanism can be admired through the transparent sapphire crystal back, which provides great aesthetic appeal.
This watch features a vintage tan dial with applied indices. To commemorate Sinn’s 55th anniversary, the limited-edition number and the years “1961 – 2016” are engraved on the case back.
