I wear a Citizen watch much like the one pictured (except with a NATO strap). It’s not too expensive, something like 200 bucks, but it’s fantastically accurate. I set it in late July to the exact time (US Naval Observatory), and since then, it’s lost exactly one single second. One second in two months. That’s incredible. Not to mention the watch will never need a battery (light powered) and it’s water resistant to 333 feet.
This is a good watch.
