how do rolex perform WR test????

[igwt]

When to rsc earlier.... Had my watch check... They told me that my SD is WR nothing to worry...... But to my surprise... When they return the watch to me..... The crown wasnt fully screwed in but at the same time was not in the pop up position where you can manually wind the watch..... When i left the shop i need to turn the crown like one or two times until it was tight enough.....


My question.... Its water proof as long as its screwed in even not that tight?

My watch doesnt fogged or any signs of water inside the case so i guess its safe....


Or when they check the WR of our watch... The equipment and test is a waterless procedure?!?!


Haha please enlighten me...

A new triplock is waterproof to its maximum rating of 500 Bar even when the crown is unscrewed. The screwed in position is to prevent the crown from being operated at depth just like the Daytona screw in pushers which have no seal but are there for the same reason.

Thank you so much for the reply.... Learned something new today....

[Vincent65]

they stick it in a vacuum

Don't screw that crown down too tight.. It only needs to be finger snug to be secure.

[igwt]

thank you guys for the info.... i adjusted it just now... hehe... i tend to over tighten the crown i guess.. hehe...

If you can avoid torquing it like a wheelnut on an F1 car it will last a lot longer!

A real watertest is performed thusly. First watch is sealed and lubed with new gaskets movement out. Then put into a dry vacuum testing machine down to a .8 vacuum. Once that's done then into a watertesting machine and say for the submariner put under 125 bars or approximately 4275 feet for half an hour. After that watch is put on a hot plate set at 47 degrees centigrade for 5 minutes then a drop of room temperature water is placed on the crystal if it fogs up you start over if not you're good to go. Whole procedure takes about 45 minutes. Hope that clears it up a bit. Rikki

Very interesting.
Any idea what a fair price would be for this test?

[Andad]

A price if it passed the test or failed?

Movement out?
What do you do to test it when the movement is put back in?
Why would you pressure test a Sub to 1300 metres?
This confuses things for me Rikki.
Can we have more details?

I think Rikki meant the SD when he said Sub.

With the movement in, only a vacuum test will let you know safely.

My own wet testing is a bit complicated and involves Fiat 500's

Remember the old VW Beetle ads - ' A Beetle will definitely float, but it will not float indefinitely."

The Sub has passed rigorous tests, in a report on October of 1953, the watch was worn multiple times during dives with an extended crown. To conclude these tests the watch was attached to a thin cord and was dropped to depth of 120 meters, (396 feet )(the maximum depth achievable with self- contained compressed air equipment) no leaks were detected after a period of 1 hour, with the extended crown. Read from WatchTime.

I got that your post was about a SD, but this fascinated me.

In those days that was quite an achievement!

My Omega SMP does 1000' now without a screw-down crown. Those must be some magical gaskets.

Yes I meant Sea dweller sub would be about 33 to 35 bars. Rikki

rolex seem to test the watches beyond what's printed on the watch. for the dssd, they test it to 16,000' - 25% more than rated. this seems their standard practice.
over engineered, I love it.

[Rashid.bk]

but why the movement out. shouldn't it test out the way it's used. also, after they put the movement back, how do you know if that is 100% sealed.
thx in advance.

Great advert for such an iconic brand - but even my eyesight has detected that the little 'red' car is in fact an Abarth 500 and not a Fiat 500.

****** retentive or what?

Thats only applies when they do a full service with full movement strip down.The case is tested first before the movement is placed into the case not much good putting a movement back into its case if it was not pressure and water proof. Once movement is back in case its tested again to be sure,if no movement service then watch is tested with movement still in case, its a slightly different test they dry test first .

^Thank you for that, makes sense.
