Sinn 910 SRS
In 2016, Sinn introduced a special split seconds chronograph model, the limited-edition Ref. 910 Anniversary. They followed this with this Ref. 910 SRS in 2018 with a flyback function. It uses the same 41.5 mm case but features a more familiar 6-9-12 three-register layout and lacks that model's extra pusher at 8 00. The movement is based on the Valjoux 7750 but modified for a column wheel flyback module from La Joux-Perret.
The watch is styled like a classic chronograph, with narrow “twisted” lugs and applied markers. The dial is white, with grey and white pulsometer and tachymeter scales on the inner rehaut. The hands are black and red, and a date window is present at 3 00.
The rear of the case features a display caseback showing the movement, automatic winding rotor, and column wheel.
