OK, so I know I need a silicone lubricant for the gasket when doing a battery change etc. But there must be dozens of different product out there...do I need a silicon oil? A grease? A spray? Are there ingredients to avoid? Will silicon o-ring grease work?

It's a pretty confusing internet out there - anyone who can help with a specific product recommendation would be appreciated!

I use some Seiko silicone grease for case gaskets (ref TSF-451). Not the cheapest (approx. 15$), and I guess any grease would do the job, don't worry too much. But Seiko is quite trustworthy when it comes to watchmaking, so...

Don't use a spray, only use a small amount of grease on the seal. The more important, far more important than lubricant, is to put the gasket right in place. If not, it could be damaged when you put the caseback on. In this case, no matter what lubricant you use, your watch won't be water resistant anymore.

EDIT : Bergeon is good too.

Here in the US, we can get silicone grease pretty easily. Check electronics places (they call it dielectric silicone grease). A lot of hardware stores also sell it as a lube for faucet o-rings.

I really don't think there's a big difference between silicone oil and grease. I have used both with good results, but I prefer the grease.

There's a joke, the punchline to which is "Oh, I see what the trouble is; you've got silly-coon implants". ...But I can't tell it here. You know: Rules and so forth...

Aaaalright, found a local watchmaker supply shop and got some Bergeon #4509:

The high vacuum pressure waterproof watch case sealant. Will prevent leakage of moisture into the case due to worn-out joints or ill-fitting gaskets even when the watch is subjected to extremes of pressure variations. Will not evaporate, nor affect watch oils. Unaffected by temperatures changes. Will not run, harden or break down on the threads. Completely unaffected by moisture, salts acids, fungus alkali or sweat.

It looks like this is the stuff I need. They had several variations, but this was the closest, especially considering I need to reuse a 20 year old gasket which, though amazingly in 1 piece still, is probably not all it should be.

I have a cheap 50m WR Casio beater which I'll try this on as well and see if my efforts prove successful with a water test.

I wonder if plumber's silicone grease is ok. It would be interesting to try putting an empty case (i.e. no movement) through a pressure test.
