Ok. I check on WUS and Rolex Forums at least 30 minutes a day. I've read thru hundreds of WR threads. I've been getting some conflicting infomation regarding the water tightness of watches.

Is a dive watch more vulnerable from:

1. the crystal gaskets
2. the crown
3. the caseback

The reason I ask is that I have seen several responses the the crystal gaskets are the most vulnerable point since it is not screwed in like the crown and caseback. Makes sense to me.

The seals are the weakest point in any waterproof watch (whether that be crown,caseback or crystal)..
If they are not up to standard (IE:old and or squashed), this is the failure point!
As for which one is more susceptible, all equally can fail IMO!

I'll agree with my esteemed colleague..

However, I will agree that the most likely to fail is the crystal gasket. It is exposed to UV light and is simply press fit in place.

The Triplock needs to have 4 separate o-rings fail and the caseback o-ring isn't exposed to anything if the back is tight...

One of the reasons for the He valve on the Sea Dweller is to let trapped gasses escape to keep the crystal from being blown off from inside pressures, so there is constant flex at that point..

Annual pressure check should keep your Rolex water tight, that is good insurance if it fails you can get the proper repairs before you end up with a case full of water. It is recommended to service your Rolex every five years, and if you dive with a Rolex that is really important to keep the gaskets fresh and new.

any waterproof system relies on gaskets, whether it be household plumbing or bits under the bonnet of your car, they all fail if not maintained, so what's the point of your question?

Annual pressure check and 5year service interval: no risk at all.

I think that crystal and back gaskets are the most vulnerable... But there is no watch with two gaskets on crystal and two back gaskets, so keep them serviced and all will be good.

Well from most posts here on TRF, there are not many saying a Rolex has let in water so i wouldn't worry about it. Keep it serviced and there shouldn't be a problem.
