Taking Dive Watches Way Too Deep

Post by koimaster » March 28th 2021, 12:33pm

Water resistance is a crucial consideration when it comes to watch design, but how deep can a dive watch really go? Thanks to the YouTube channel Beyond The Press, you can watch as two simple dive-style watches (one 100M resistant Citizen, and one 300M resistant Dugena) are both tested not only to their rated water resistance, but also for the maximum pressure possible for the testing device – 300 bar, or, you know, 3,000 meters.


That's no typo. The channel, which does all sorts of experiments (many with one of those awesome hydraulic presses), is using an HPC Deep Sea Chamber to test each watch up to a maximum "depth" of 3,000 meters (300 Bar or more than 4350 PSI). As stated by the thumbnail image for the video, the results are indeed catastrophic. Destruction notwithstanding (it's certainly fun to watch), I thought it was really interesting to see just how well each watch does when subjected to pressure well beyond each model's depth rating.

One point worth noting is that both watches pretty dramatically over-performed. The Citizen did not stop until three times its rated depth and the case didn't fail unto thirty times its rated depth. The Dugena, rated to 300 meters, didn't stop functioning until it reached a depth over 1 kilometer.

Then there is the video of off-the-shelf Seiko 1000m Tunas (auto and quartz versions) going beyond 3000m and coming back completely unaffected. Serious engineering.

Hmmm, why didn't Hodinkee test a Rolex?

Surely they could have gotten some freebie samples from all those deep divers the Bazinga so dearly loves.
A Submariner wouldn't survive but a Deep Sea likely would. It would be interesting.
