I can help you with this.

The specification means exactly what the speciffication says. In this case, under a pressure equivalent to 50m water depth, no water will infiltrate a properly-assembled Speedmaster using new parts. Omega has that specification and they have an approved test. Archer has shown it above; a case is put into a water chamber, a ram is used to increase the pressure beyond the specification to an approved safety margin, and left a while to see what happens. Then another test to see if any water has infiltrated.

Now, Omega has recommendations on how you, not knowing jack (not a dig, you don't know what you don't know) can apply this specification. Dunking your watch in the sink will not cause infiltration. Taking a shower with your watch will not cause infiltration. Snorkeling with your watch will not cause infiiltration. If your watch falls off your wrist and the water is 30m deep, it will not be infiltrated.

Some people in the past have claimed that there is some mystical force called "dynamic pressure". Like waving your arm about underwater imports some huge amount of pressure on the watch.

That is, in a word, "Bullsh-t!". You'd need firehose pressures to cause infiltration. A person cannot move his arm fast enough and the water would get out of the way.

A vintage Speedy that has been recently serviced and pressure tested can indeed be worn in the pool. Feel free to not wear yours.

OK, you can't possibly be this stupid. I can use a wrench as a hammer too. Won't meet the spec for the wrench OR the hammer. Specifications are just that... a series of benchmarks with tests to indicate whether an object meets the specification.

An airplane makes a horrible boat, too, but I hope it floats long enough to get me off off it!

Right on cue...

 

"wrestling with a pig" is well-illustrated here.

 

Tom,
Please don’t bring logic to this thread It is helping pass a boring Sunday evening!

Talking of wrenches, here’s a spanner in the works......

 

That's been quoted before. Nice specification.

Tom

 

666 going down!

 

Not a Snorkel- don’t have to drink

 

Love it. Henceforth SM shall be known as Dougal.

 

Well I'm happier that you are tempting to poke fun at me, as it makes a nice change from you making false and inaccurate claims about what I've written.

 

Right you are Dougal.

 

Please wear yours. And send a pic showing it? Anyone for that matter - please send a pic showing your vintage speedy underwater.

 

I wore my Speedmaster in a hot tub. Don't own it any more, but didn't damage it either.

As I said... you CAN. Not MUST. Feel free not to. You should, however, ask your watchmaker if your Speedmaster was properly serviced and pressure tested.

Tom

 

It would be interesting to hear what warranty is given by said watchmaker? and if they will stand behind the cost when it goes tits up.

 

This sounds like the intro to a joke:
The Pope, a Rabbi and a Speedmaster were in a hot tub.....

 

The Pope looked at the Rabbi and said...

 

Oh-oh, are we playing “who’s line is it”???

 

The pope looks at the Rabbi and says
“ I hear that Speedmaster is rated to 50 meters”.....
