====== Sinn 910 SRS ====== **Ref. 910 SRS** is a limited-edition [[flyback]] [[chronograph]] watch from [[Sinn]]. ===== Overview ===== In [[2016]], Sinn introduced a special [[split seconds]] chronograph model, the limited-edition [[Sinn 910 Anniversary|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. **Movement:** * Mechanical [[automatic chronograph]] movement [[Valjoux 7750]] 28,800 A/h * 31 [[jewels]] * [[Flyback]] [[column wheel]] modification by [[La Joux-Perret]] **Case:** * [[Stainless steel]] * D 41.5 mm, H 15.5 mm * [[Sapphire crystal]] and [[sapphire crystal]] caseback, with [[anti-glare treatment]] on both sides * [[Waterproof]] to 10 bar, low pressure resistant **Functions:** * Hours, minutes, [[small seconds]] * [[Chronograph]] 12 hour counter, 30 minutes counter, [[flyback]] 60 seconds counter * [[Date window]] **Bracelet: ** * Leather strap or steel bracelet **Production:** * Production [[2018]]-Present * Predecessor [[Sinn 910 Anniversary]] {{tag>Watch_models Chronographs Sinn_Instrument_Chronograph_models}}
