Sinn 857 UTC TESTAF With Strap and Bracelet - 2016
Sinn 857 UTC TESTAF
Here we have another magnificent tool watch from the masters at Sinn.
The Sinn 857 UTC is their GMT, and has always been a favourite of ours, and this particular version is that bit more special, as it was tested and certified to the the “Technical Standard for Pilot Watches” (Technischer Standard Fliegeruhren – TESTAF) by the Aachen University of Applied Sciences, meaning it is suitable for professional use as a Pilot's watch, and bears the TESTAF logo on the dial. It is also differentiated by it's use of orange for it's second time zone functions, which looks amazing against the matte black dial.
This all sits within a 43mm bead-blasted steel case, and is usually mounted to a very cool orange and leather Pilot style strap, but in this instance also includes a steel Tegimented Sinn bracelet.
Power comes from the tried and tested ETA 2893-2, meaning ease of service and reliability. The second time zone function is operated via the crown, and is very readable and easy to use. On top of that, it also features Sinn’s Ar dehumidifying technology to keep moisture away from the movement, and is also anti-magnetic. A proper tool watch in the truest sense of the word.
This particular example was purchased new locally in 2016 and presents in TZ 'Near Mint' condition. Case shows barely any hint of use, with some very small marks on the case back being about the extent of it. See images for full condition details.
Bracelet includes all links, and shows only the most minor hints of use.
Service history is unknown. All functions operating as they should, and keeping time at around +12 seconds a day at high 200's amplitude dial-up on a timegrapher.
Includes outer box, inner box, instructions, warranty card (expired), strap tools, Loctite, OEM strap, and spare links to complete the bracelet.
