"Strong history shows in great watch"
Comments about this watch: Was leaning towards a Rolex GMT when I came across an review of the Sinn TESTAF technology and the new DIN 8330 watches. Did my research and purchased the 103 TI UTC IFR.
WatchBuys was easy to deal with and item arrived as promised. I swapped the strap for a NATO strap and love the watch. The chunky size and useful features like ease of readability and no-glare crystal belie Sinn's history combined with the new technology and titanium case make for the perfect travel watch. I can wear it all day and night and forget I am wearing it. Highly recommend.
TESTAF Certified Pilot's WatchesLothar Schmidt, Sinn's CEO and owner had long been disturbed by a lack of technical standards for defining a "pilot's watch". As an engineer, Mr. Schmidt was fluent in standards for diver's watches, anti-magnetic watches and the many other technological standards used to manufacture watches.A widely used reference for standards is DIN, or the Deutsches Institut fr Normung (German Institute for Standardization). Oddly, he discovered there were no DIN standards to cover pilot's watches where such standards existed for example for diver's watches.The new "Technical Standard for Pilot's Watches" (TESTAF) was developed by the Aachen University of Applied Sciences and establishes the suitability for professional use as a pilot's watch.
