Omega Water Resistance chart update . . .

Just noticed Omega have changed the Water Resistance Chart on their website.

Here we go:

30m, 50m and 100m good to snorkel with!

Look forward to some snorkelling with my new 100m Speedy then!

I can't speak for everyone, but when diving I don't wear my psudo-expensive watches because in the process of getting gear ready, suiting up, taking gear off, it's just so easy to ding, smack, and bang your watch up. Not a big deal on my Timex Reef Gear, but painful on a more meaningful purchase...

I'm most concerned with sand at the beach scratching the AR coating.

I purchased a used speedmaster from an authorized omega dealer and they advised me not to get my speedmaster wet because it was not a divers watch. What is the factory rating for this watch?, The watch had no B&P's. any info would be appreciated.
Thanks Rick............

I am not a watch mechanic, however, the pictogram card from my 3570.50 says
"5 Bars." A bar is the practical equivalent of an atmosphere of pressure, or ATM. Ambient pressure at the surface is 1 ATM, and every 33 feet of saltwater increases the ambient pressure by one ATM. So, five ATM is 132 feet of saltwater. It's beyond me why an AD would make a recommendation to pamper your Speedmaster like your Blackberry. I don't dive with mine, but I never worry about showers, rain, car-washing, etc.. Also can't imagine that NASA would've selected a watch as water-resistant as a toaster for astronaut issue; after all, until the shuttle, astronauts landed in water. I make sure the crown is pushed in, and then don't even think about it.

ISO 2281 is different than ISO 6425
The first is air pressure,the second is water one.I think the Speedy has 5 air ATM,and the Seamaster has 30 water ATM

Isn't it strange that you can take the Speedmaster moonwatch to outer space, but barely in to the shower?
I mean, NASA must have done some serious pressuretest on the watch. And obviously it did well, but its still marked to 30m?

I used to wear my Speedmaster all the time (to bed, to work swimming, the shower, kitesurfing, ok not mountain biking,). Low and behold one fine day I noticed condensation inside the crystal. Fortunately, my local AD where it was purchased serviced it under warranty and since then I have never worn it in the water again.

It is my understanding that the word waterproof is no longer legal for use in North America, and quite possibly the Western Hemisphere, and many parts of Europe. It has been this way now since the 1950s IIRC. It implies that it is impossible that a watch could leak. That is not the case! Tell me if you have seen either a Rolex or Rolex literature that uses the word waterproof!

Hello,

I have a SM 300 chrono and dive (with air) is limited to 60 meters so something like 200 feets. The watch have done more than one dive and i like to use the rotating bazel and tables/(do not no the transalation of "profondimètre" ...) to check the discrepencies with my computer

same purpose for the sd16600 but they are not diving at the same time, i have only 2 hands

Fred

Water resistance

Attached is my 17 year old seamaster
used for diving for around 10 years of the 17 and never an issue with salt water damage, just a rinse afterwards in some soap and fresh water, always get the case checked at each service for any corrosion etc and to date nothing wrong. these watches are built to withstand anything so relax and use them

I have worn a Speedmaster for 25 years in every "reasonable" situation. Showering, swimming, etc. I never thought about babying it until I started collecting Speedmasters and began reading about what not to do from other collectors.
It's a tough watch, and while I wouldn't push it, I have been on the bottom of a number of pools over the years...

What's the latest on modern Speedmasters? I don't plan to do too much swimming or showering with my Speedy Tuesday, but I'd like to feel comfortable giving it a good cleaning under water from time to time.

Any advice on this? Thanks.

Chadri, the Omega website indicates 50 meters/167 feet for the Speedy Tuesday.

I wouldn't bother myself so much. It is beautiful, and it is seaworthy!! Just enjoy it.

I don't think you are correct?

On the surface there is no pressure on the watch case.
inside = outside.

Take it down 33 feet and you have 1 Bar (approx 14.8 PSI) on the case.

5 Bar = 165 feet.

I've heard some folks talk about pressure changes as you move through the water - would that be a reason some of the lower rated Speedy's are "not advised" for swimming and such?

Like you swing your arm as though doing frontstroke, causing an angular increase in pressure, and so on.

Or is that more of a myth/inconsequential to the pressure rating?

Omega watches were made specially for diving. Helium valve allows them to regulate pressure under water, so you won`t find better waterproof watch! I`d bought Seamaster if I could, very attractive watch for me.

The helium escape valve does not operate under water and has nothing to do with regulating the pressure under water.

Swing your arms as much as you want above, into or under the water.
It will not have any effect on the water resistance/pressure rating.

Unless you swim with the watch inverted on your wrist (i.e. dial down) the frontstroke creates a negative pressure. If you were doing a backstroke style swim that would be increasing the g-force with which the crown and dial strikes the water.

Either way, an Omega that passes a 3 bar pressure test will have no troubles. The reason for a warning is because people have a habit of not getting regular service done nor do they have annual pressure tests done. The increased pressure Swimming or Springboard Diving imparts could force water into a void created by perished gaskets.

Not sure what this has to do with springboard diving and perished gaskets.

Wouldn't water get past perished gaskets without all this swimming and springboard diving misinfo?

A Rolex watch is rated to the depth stated for that model plus a safety margin when serviced and tested by a RSC.

As for the 100m rating for Omega meaning it can just be submersed in water?

Well that may be for Omegas but not for Rolex watches.

So go swim, jump, dive and splash around to 300m down with your Submariners.

Post up some pix.

The safety margin is an ISO standard/rule (+25% of the rated depth) but this is never checked during service, watches are tested at the rated depth. Same goes for every other brand, as long as it's an ISO certified dive watch.
