Sinn Introduces a Cockpit Clock for the Wrist
In the era before electronic timekeeping, fighter pilots relied on mechanical navigation clocks on their instrument panels known as navigationsborduhr, or NaBo for short. Sinn got its start making instruments and watches for pilots and planes, and one of its earliest products was the NaBo 17 ZM made for the Tornado fighters of the Luftwaffe in the 1970s (which remain in service today). Now Sinn has reimagined the NaBo 17 ZM for the wrist, creating the 717, a massive chronograph powered by the proprietary SZ01 movement. Initial thoughts The historical basis of the 717 is impeccable, and Sinn has managed to translate much of the cockpit clock feel into the wristwatch, right down to the details like the “pump” pushers and knurled crown that resembles those on the NaBo 17 ZM. The 717 is impressive in the manner that most of Sinn’s “tool” watches are – it is perfectly legible and the case is virtually scratch-proof – but it also seems way larger than necessary. At 45 mm by 15.3 mm it is massive on both counts, and will probably feel extremely chunky on the wrist. Priced at a bit over or under US$5,000 depending on the strap, the 717 sits at the high end of Sinn’s offerings, but is priced similar to other watches with the SZ01 movement. It’s fair enough, though the size will not be for everyone.
