First Look: The Sinn 910 SRS Flyback Chronograph

Share this story:

In 2016, Sinn put out the 910 Anniversary Split-Seconds Chronograph, a limited edition of just 300 pieces boasting a modified, top-grade Valjoux 7750 and a complication not common to the brand. It was a commercial success for Sinn, and for 2018, the German favorite has decided to extend the 910 series with the 910 SRS, a general release model equipped with a flyback function (SRS, by the way, stands for “Stopp-Retour-Start”).

The movement inside the 910 SRS starts out as a Valjoux 7750. It is then heavily modified by Sinn in partnership with renowned movement house La Joux-Perret, replacing the cam mechanism with a more traditional column-wheel and building in the flyback function. What is a flyback chronograph? It essentially allows you to reset the chronograph without first having to stop the watch. In a traditional chronograph, you have to stop and reset the chronograph before you can start it up again. In a flyback chronograph, all you have to do is press the reset pusher and it does all the work. This new caliber will be a mainstay in Sinn’s arsenal, so we can expect to see it rolled out in future releases.

Aesthetically, the SRS shares a lot of design cues with its older brother. You still have the cream dial with the grey, red, and black accents—always an attractive color palette in my opinion. Despite the large amount information on the dial (three registers, multiple scales, etc.), the 910 is highly legible, even at a glance.

The case measures 41.5 millimeters in diameter, 15.5 millimeters thick, and features a lug width of 22 millimeters. It’s rated to 10 bar and is built in compliance with DIN standard 8310. Sapphire glass sandwiches the case, with double-sided AR on the top glass for maximum clarity. The case also features Sinn’s D-3 system, which creates a more reliable seal in the crown and pushers.All in all, this is another knockout for Sinn. The 910 SRS comes mounted on a whiskey shell cordovan strap or a fine-link bracelet. The former is $3,960 and the latter is $4,260, and can be pre-ordered right now through WatchBuys in North America. Sinn
