Why Dive Watches break when you dive too deep?

I might be too late for this to be seen but you should try a rupert’s drop in the chamber. It may be too strong to break but it does have a bubble inside and is worth a try!

People can and do survive 30-40 bar, while working. Look up saturation diving. The record is at 701 meters. This equals 70 bar.

[@windhelmguard5295]

what i was able to deduce from what i have seen here is that the main weakness of the watch is the air inside because, since gases can be compressed, the outer pressure can crush the watch and either bend the back panel inwards to disrupt the mechanism or crack the glass in the front. thus i hypothesise that a watch that filled in with a liquid, which can not be compressed, would hold up against the water pressure much better as the liquid inside the watch would support the structure from the inside. thus i suggest your watch maker try to make watch filled with a hydrophobic liquid like mineral oil or if that's too sticky maybe something with low viscosity like diesel fuel or kerosin?

[@bornabosnjak810]

Great observation, and quite true! There are several oil-filled watches by the likes of Bell and Ross Hydromax and Sinn UX that are rated for extreme depths (e.g. the Sinn's movement is rated for 500 bar, the case for 1200 bar).

[@tomoxfford]

Great video. I always suspected a screwed in crown didn't add any water resistance. Stops it being pulled out by mistake and helps protect it from knocks but water pressure will keep it tightly in place under deep water. A Rolex Deepsea is rated at 3900m... if you can find a brave owner to lend you one!

[@mikep5478]

Very cool demonstration .. I see a lot of folks who question WR rating when watches don't have a threaded crown. The quartz lasted deeper than I guessed. Thanks for the video.

[@Beyondthepress]

One thing that is good to know is that these are brand new watches so they might be not this good after many years of use

[@ctsean]

With rare exception, the threading contributes nothing to water resistance - it's to prevent the crown from getting pulled out by accident while diving.

Seiko Turtle is rated at 200 meter which is 20 BAR(ATM). The watch stop at 80 bar or 800 meter which is 4 times over rating, and the glass shattered at 120 BAR or 1200 meter, that is 6 times over its rating! Good job Seiko

[@ZAV1944]

With the right practice and equipment a person can scuba dive down to 1000 feet or 305 meters but I think that you would probably abort the dive if your watch failed as you need that to tell how long you have been underwater and how long your decompression stops will be.

@10:00 the watchmaker is disappointed that a diver's watch rated for 200m stopped working at 850 meters (85 bars)...he didn't seem to be joking. I think the Turtle did perfect! It would be nice to see a watch with sapphire crystal tested here. The sapphire is harder but more brittle than the Hardlex crystal in the Seiko. The expectation would be to crack at high pressures not to shatter like the Hardlex crystal did.

[@panospeter_pan4257]

The thickness of the crystal is more important. Citizen and seiko make some of the best affordable divers .reliable etc. They lack is specs and other things compared to microbrands but they are reliable.with great history.

[@able-fox]

I don't think the crown/stem were the failure point. I think the steam bent because the movement was pushed backed when the crystal failed. Since the case back of the Seiko held up so well I would be very interested to see what would happen if you installed a new movement and a thick domed crystal.

That Seiko Turtle is only ISO 6425 rated for 200 meters so reaching 800 meters before it stops is really impressive.

Seems like the ones with better case-backs will be higher on the list, to be sure. The general consensus in 2021 if you want Sapphire is to get an Orient Kamasu. The Seiko are good, but getting over-priced. If you can't swing the sapphire crystal, the entry-level Orient should be just as road-worthy. Err, sea-worthy.

[@paulg3336]

I wonder if it is feasible to design a watch that is filled with a low viscosity liquid that won't compress. The movement would have to be designed specifically for the higher viscosity of the fluid, in order to function correctly. A digital watch filled with liquid does not have that problem,of course. Explosion proof pressure gauges are often filled with liquid. It would be interesting to replace the crystal on the seiko watch and fill it with silicone oil, being careful to eliminate any bubbles, and running the experiment again to see what pressures can be resisted.The movement doesn't need to be functional to do that. I did a search and found that the Ressence Type 3 watch is liquid filled and that some top dive watches are also liquid filled.

[@MrTchou]

You can on quartz watches, if you fill up a mechanical watch it won’t run as fast as it should and lose it’s precision.

[@paulg3336]

@@MrTchou That is just a matter of design. There is no reason a designer cannot design a mechanical movement that will work perfectly well in a high viscosity environment i.e. filled with liquid. Air has viscosity and these watches seem to deal with that ,don't they? Clocks actually use it. They often have a regulator for the chime mechanism that uses a fan to control the speed.
