Hi,

I posted a photo of my opened caseback in my local forum as below;



Someone commented that there's a missing rubber gasket somewhere. Is this true? Thanks for any advice given.

Yes there should b a black rubber gasket to keep moisture away. If u install one make sure to pressure test it just to b safe. Maybe a movement service if it hasn't been done in the last 5 yrs.

Yeah there's a rubber gasket that mates the caseback to the case...not sure what kind of watchmaker would put the watch back together and ignore it....better get that done stat....while you're at it get a full service done to make sure there's nothing else weird going on.

It's a cheap fix, just have one installed. While you're at it, see if your watchmaker can pressure test it afterwards.

It's Not about the costs, but where should I get it? Possible to get from RSC without a service?

Look at this on eBay http://www.ebay.com/itm/310359140371

Of course it will be ideal to get original parts. Looks like I need to visit various forums like vrf or the local watchmakers.

The gasket that will fit that case is an "O" ring gasket that is a perfect fit in the groove around the case opening. It must be of the right diameter, and the exact circumference, and must be lubricated with silicon grease. Then, use your dedicated Rolex Oyster case wrench to tighten the case back. Then, put the watch into your waterproof tester to assure it is water tight. The short answer is, take it to a watchmaker who has what is needed to do the job right!

I must gently scold here....And you were looking at UG the other day?????? To pursue this hobby without the support of a competent watchmaker will end in disappointment. I do understand that they are in short supply in some markets. Rolex service sb easier to find. UG? Don't even think about it if you've not sourced a vintage repair shop.

Omg... That reminds me to either source a UG recently serviced well or travel to Europe to find a good watchmaker as unfortunately in Singapore, UG flies under the radar for most...

I thought you might be in Singapore ... yea UG is problematic for you. They don't like humidity either.
