Pay attention to the following when selecting the watch that’ll accompany you into the cockpit:Robustness: As you’ll see, a pilot’s watch needs to be able to withstand intense g-forces, temperature differentials, and, possibly, getting ejected from a cockpit and ending up in a field somewhere…hopefully attached to a wrist. Legibility: A pilot’s watch needs to be highly legible — meaning, a pilot needs to be able to get a picture of the time with even the quickest glance. That’s why it’s generally best to do away with all superfluous ornamentation. Size: Pilot’s watches are one category in which size — due to the aforementioned legibility factory — really does matter. While there are well known examples of smaller pilot’s watches, a slightly (or massively) larger case and dial really does help if you’re actually flying with your watch.Reliability: Sure, you could argue the same needs to be true of field or dive watches — and you’d be right. But regardless of whether the watch is mechanical or quartz-powered, it needs to be reliable, which means it needs to be well built. Don’t skimp on price.Operability: Ever wonder why so many vintage (and modern) pilot’s watches have those oversized “onion” crowns? That’s so you can grab ‘em with gloved hands. Your watch needs to be easy to use while flying a plane — otherwise, what’s the point? Anti-magnetism: While this is less crucial today, vintage pilot’s watches such as the “B-Uhren” designed for the Luftwaffe during WWII and the MK 11 designed for the RAF in the late 1940s were produced with soft iron cages around the movements to prevent magnetic interference from instrumentation and engines.
