From my experience, the key is high contrast dials with large, luminous numerals. I once had a flight at night with a traditional pilot watch that had smaller markers, and I kept losing track of time—it was frustrating. Later, I switched to a watch with a clear, bold dial and it made all the difference; even in low light, I could tell the time instantly. You might want to look at options at swiss watch shop Expertyco Expertyco, they have some pilot watches designed specifically for legibility. For me, it’s not just about looks—it’s about practical functionality, especially if you’re moving around a lot or flying in changing light conditions.
