After appearing on recent buzzy releases like the Mido Decompression Timer, the Blancpain Air Command, and the Oris Caliber 400 Limited Edition for HODINKEE, the counter-clockwise timing bezel hit the big time late last year on the Tudor Pelagos FXD, its most mainstream application in decades.

This story has been a long time coming. I’ve always thought the countdown bezel was a far more functional alternative for daily life than the “count-up” approach used to measure elapsed time that is conventionally found on dive-watch bezels

My life operates on a schedule. The days are never identical but I generally have a plan of what I’m going to do and at what time I’m going to do it by the time nine o’clock that morning rolls around.

Certain days, for instance, I’ll have close-to-nonstop meetings. When my calendar does open up to breathe, I can use the countdown bezel on my Oris to mark the time my next meeting starts – say, in 45 minutes – and keep track of how much time I have available to run out for a cup of coffee.

Or when I’m at the airport, I can use it to mark the exact time my flight is scheduled to board. Then I know exactly how much time I can waste moseying around the Hudson News and snacking on apps at the airport Applebee’s. The countdown bezel is also just as effective whether I’m interested in at-a-glance timekeeping to the closest five minutes or down-to-the-minute precision.

Most timing bezels don’t allow for that. Your typical Seamaster or Submariner, for instance, has an elapsed timekeeping bezel that is best used to indicate how much time has passed since a specific activity has started. If that sounds familiar, it’s because there’s already another complication that accomplishes the same task with greater precision – the chronograph.

I’m not saying that a chronograph is better-suited for tracking dive times, and I’m not saying that a countdown bezel would be a better option for a professional diver. But for my Google Calendar-dominated life? A countdown bezel just makes more sense.

There’s a reason the ultimate “functional” timepiece, the G-Shock, offers a countdown timer as part of its standard kit. Same with Apple Watch. I think for most people, it’s far more common to have a defined end point for an event rather than operating with an open-ended schedule.

At the end of the day, I enjoy practical watches. I appreciate the purpose-built tactility of a tool watch. But I’m also not a fan of cosplaying as something I’m not. I don’t have a dive license, so why should I care what direction a bezel has to go in to be ISO certified? I don’t need a specialized piece of kit to monitor time spent underwater. Which is what makes the use of a countdown bezel on the Pelagos FXD somewhat ironic.

The FXD was designed in collaboration with the French Navy, to meet their own specifications. And the bidirectional fully graduated countdown bezel was selected intentionally in order for timed navigation between waypoints underwater. I don’t expect to start working nights as a French Frogman anytime soon, but I would absolutely welcome the opportunity to wear the Pelagos FXD.

It took Tudor working with a special-ops dive team to create the version of their professional-grade tool watch that’s most applicable to my largely stationary existence. Maybe that’s the wake-up call other watch brands need to realize that us office folk need tools, too.
