Do you ever dive in your DD or DJ? Why not?

[Slimpee]

If a DJ is OK for this lady, it’s probably OK for you:

I would not hesitate if the OP or DJ has been serviced/pressure tested.

Precisely, this is a good example.

I would wear my DJ down to a depth of say 130ft recreational diving without giving it a thought. Why not? That’s about as deep as any recreational sport diver is likely to go and that’s only 1/3 of its static water rating.

The DJ is more than capable of this, in the same way a sub is, assuming the seals are all good etc. Sylvia Earle proves this continually.

People do that. The early models especially are quite capable.

I did my dive accreditation with a young lady who worked in her father’s law firm. She dived with her Datejust and it was fine. This was on a reef in Byron Bay. The watch was a gift from her father I asked her about it and she said it’s a watch for anything.

Jack Nicklaus did everything with Day Date, including scuba and and fishing.

"A watch for anything."

I like that.

That's how I like think of my Sub date and skx013. My Omega Speedmaster, I'm a little more careful with that one.

[mister_poom]

I scuba dive with a computer watch: Suunto. But if it's snorkelling, swimming, I wear any watch.

[gtnator]

Submariner is my beater, I use that.

I’ve dove for many years wearing my DJ up to a 100-120ft with no issues.

[Pongster]

Are gold watches OK to swim with in a chlorinated pool OR in seawater?

[nikesupremedunk]

Are we talking about actual diving or just going for a dip at the beach on vacation? I'd be totally fine taking any of my Rolexes for water activities. My Speedmaster, I'll have to sit that one out.

[myporsche]

I have with my sub, I wouldn't with a DD if I had one due to lack of crownguards and especially no oysterlock would make me super nervous.

"The Oyster case is guaranteed waterproof to a depth of 100 metres (330 feet)." Which is deeper than the 130' that is recommended for a recreational diver. Have you ever seen anyone diving in their DD?

May want to look up Sylvia Earle.

Watches rated to 100 meters are good for surface swimming only but should never be used for even shallow diving, 20 feet or more, where 200 meters is the absolute minimum.

An object submerged in 100 meters of perfectly still water has X number of atmospheres of pressure against it. The second you move that object, the pressure against it goes up exponentially the faster the object is moved.

This is the very reason why dive watches were invented in the first place. Rolex would not have a Submariner or Sea Dweller line with triplock crowns if this were not true. It's why Rolex changed from twinlock to triplock crowns for the 5513 and 1680 when they figured it all out. Those twinlocks on the early subs were a leak point under pressure.

Sorry, but your statements (in bold) are wrong.

The pressure against any object moved underwater does not increase exponentially with the speed of the object.



That result means the following:

Moving a Submariner (with a 40 mm diameter dial) with a very large speed of 2 m/s horizontally underwater, i.e. keeping the depth unchanged, results in a force of about 2,5 Newton, which corresponds to an additional pressure of only 0,00025 bar.

At a depth of -100 m, the same Submariner is exposed to a water pressure of about 110 bar. Therefore, moving a watch underwater adds a totally negligible pressure with respects to the -100 m depth.

Yup, I misspoke when I used the word exponentially and I'll be sure to let my SCUBA instructor know that he should brush up on his math and physics before teaching his next lesson on that subject, as it stuck in my memory all of these years later. Thanks for pointing that out. Gotta love Google...

Someone on this thread said the DD and DJ are “obviously dress watches”.

How far we’ve fallen. Sir/Ma’am, these are sport watches. Oyster cases, safety lock clasps on solid metal bracelets and sapphire glass.

They are far safer to dive with than any old time Subs with their 316l steel cases, plastic glass (The Submariner did not get sapphire until the 1990s) and flimsy bracelets.

It's always good to get the basic physics right ;-)

The additional force onto the watch (moved horizontally) scales with the square of the speed.

Absolute values of force and pressure are extremely small compared to the water column!

Agreed and thanks for nicely pointing that out. I appreciate learning something new at the same time. You could have shredded me for being dogmatic. Lol I knew the moment after I posted that I should have actually double checked my statement. I'm definitely NOT an expert!

Smart divers understand that SCUBA can be a deadly hobby and things can go bad real fast, redundancy is a very important component for safety’s sake. Every intelligent diver now use octopus rigs which have a spare regulator in case the primary craps out for either the person wearing it or his/ her dive buddy in the event of failure. Many of us also carry a pony bottle on deeper dives for emergency air in case theres a failure in the primary tanks. Redundancy saves lives every year. .

Another important t safety redundancy is timing.The vast majority of divers now carry dive computers but what if that craps the bed at depth? the diver needs to know his bottom time and or do compression stops. Smart divers have the simple back up dive watch which covers both features which have saved many lives.
Divers who don't have a back up watch are rolling the dice with their lives and those who think are aren’t a good tool to have are uninformed and those who they are just folks trying to “look cool” are nonsensical.

I agree. As someone that’s had a dive computer take water on at 160’ during a nitrox dive I always wear a watch and have my tables stuffed in a weight pouch. I also have a second compass and spare safety sausage when doing some gnarly drift dives or when in bad currents.

Found this stashed away in my files (no I.D. as to from where it came):

Watches are classified by watch manufacturers by their degree of water resistance which, translates to the following (1 meter ≈ 3.3 feet):

Water Resistant 3 ATM or 30m Suitable for everyday use. Splash/rain resistant. NOT suitable for showering, bathing, swimming, snorkeling, water related work and fishing. NOT suitable for diving.

Water Resistant 5 ATM or 50m Suitable for swimming, white water rafting, non-snorkeling water related work, and fishing. NOT suitable for diving.

Water Resistant 10 ATM or 100m Suitable for recreational surfing, swimming, snorkeling, sailing and water sports. NOT suitable for diving.

Water Resistant 20 ATM or 200m Suitable for professional marine activity, serious surface water sports and skin diving. Suitable for skin diving.

Simply reporting what I found. YMMV under various circumstances.

If I'm doing anything requiring decompression it's double everything. Back up pony tank with completely separate reg, two computers, two straps on my mask, and my gauges have a dive timer with depth gauge. My watch is along for the ride.

Curious how old that data is. 20 ATM is just shy of 300 feet. 200 meters is approx 656 feet. Quite a difference between the two numbers the other numbers don’t jive either. I’ll add, the Submariner was rated at 200 meters for a long time and was one of SCUBA diving standards for many years, short of deep saturation diving and performed very well doing what designed to do and still does.

The definition of skin diving is open to interpretation also. Back in the early days of SCUBA the term skin diving also applied to SCUBA without a wet or dry suit and is sometimes is used today in some circles.

Definition taken from online - skin diving- “the action or sport of swimming under water without a diving suit, typically in deep water using an aqualung and flippers” that said most today understand that skin diving is snorkeling and SCUBA is SCUBA.

Thanks bmb. Thanks also for your detailed mathematical post. It got the point across very well, I almost attempted to do the same but would have flubbed the numbers. I’m not as good as you in math, I even had a little difficulty in the tables in SCUBA class many years ago. Lol

[DJJon]

Another vote for swimming in the pool with the DJ so that's 3.3 meters deep at the bottom.

I wouldn't even try it in salt water not because it couldn't handle it but I have a slew of watches rated up to 1000m of titanium and ceramic that are meant to be in salt water.

Yes - but do watch out for hot tubs.

There was a previous post about that I’m sure someone with a better memory than me can link to.
