Dive watch with the deepest rating?

it's not like you're gonna actually GO 300 mph...

Who says we wouldn't? :-D :-D :-D

Yeah I think if I had a car like that I would push it pretty far; because at least it is possible. I push mine up to the redline every now and then.

On the other hand the only way anybody is going to 10.000 or 12,000 feet is dead way before they get there and coming back in a soup dish. I understand the technical problems and logistics involved with deep diving and I will be surprised if anyone dives significantly deeper than the current record at 710 meters within hundreds of years much less in my life time. I believe this would be a significantly more difficult task than going to the Moon or Mars even though it is only a few miles away.

There's a difference between it could be done with technology at hand and there is no way possible to do it.

The first thing that comes to my mind when I hear of diving to such depths is...........Why?

That's what they invented submersibles and robots for.

Sorry, maybe that was a bad analogy. Scientists need to find a way to allow us to tell time after we're dead in that case.

Depth rating really relates to a safety factor multiple. I once heard that realistically, a factor a 5-10 times actual depth should equal depth rating. I link Sinn's philosophy of "any attainable depth" for the UX or EZM2. That says it all

One thing about the ultra deep ones is that they have super thick sapphire crystals. Won't have to worry about impact on them, hopefully. Prabably more of a safety factor if you didn't have the crown screwed down or something, as well.

I have always bought divers even though I dont dive. Partly because of their sturdy looks, but I once had a non diver dial badly moisture up on me when climbing a mountain & decided I didn't want this experience again. For me a diving watch with a ridiculously unnecessary depth rating, like my Breitlings Superocean & Seawolf, nevertheless ensure protection when swimming in the Dead Sea, climbing in the Alps, enduring my young sons' vomit on it etc. Such depth ratings also assure me that the design, engineering tolerances & build quality are awsomely constructed.

I agree that a safety factor is a good idea over the stated depth rating but in engineering design work that is a given with virtually anything. Seadweller's stated depth rating of 4000 feet is less than a factor of two to where they have been on real working dives (2100+ feet) not just a pressure test but tough working conditions and thermal shock as well from exposure to ambient water temperatures probably near freezing and hot water suit temperatures well over 100 degrees F. while at 2100 feet. So I am sure it has a built in safety factor of more than 4000 feet.

I have always said that if these kind of pressure ratings are not that big aof a deal anyway when you consider the extremes of industrial equipment with working fluid pressures in excess of 25,000 psi (equivalent to approx. 55,000 feet of water pressure) which are in regular use under much tougher conditions than any watch undertakes.

Isn't that what all watches are about, some form of status? If it isn't the deepest rating, it's the most expensive, the most limited, etc. We are all guilty of that in one way or the other, but it's interesting to see that people find that the way these deep sea watches are constructed offer great reliability to the wearer, with sapphire crystals and sturdy construction etc.

An interesting thought that people find that watches that can reach extreme depths are going to be strong enough to survive everyday life, and sometimes I think everyday life is more strenuous than what these watches were made for originally.

I owned a hydromax for a few months....great watch, the effect of the dial under the oil was really amazing. I always equated it to looking like the dial and hands were actually painted on the crystal, they appear completely flat from any angle with no distortion.

One interesting note, a user on another forum who is also a saturation diver made an excellant point regarding oil filled watches. He pointed out that even though the watch may survive from being crushed it's unlikely it would still function since at that depth the incredible cold would kill the battery.

Something I had never considered before.

Better check with an oceanograher because I am not sure what you think the incredible cold temperature would be but I doubt if it is a factor. I don't think the water temperature in the ocean goes significantly lower than freezing in any water depth. I have worn quartz and automatic watches while diving in December in baltimore harbor and on the outside of my glove in the winter in 14 below zero F in the wilderness without any problems.
