The more traditional approach to the pilot’s watch is mechanical, and few do that as well as Sinn.If you often by airplane,you should by a aviation watch.
Their 857 UTC TESTAF ($2,470) features a 43mm hardened steel case with a legible dial offering not only local time and date but also a display for a second time zone. “TESTAF” (German for “Technical Standard for Pilot’s Watches”) means that the 857 UTC has been certified for use as a pilot’s watch: it’s both water resistant to 660 feet and low-pressure resistant with an active anti-fogging system, making it suitable for high-altitude use.
