Should I use silicon grease on the Crystal Gasket?

[bruce79]

I'm just curious, I know to silicon grease the case back gasket and the gasket in the crown but should I use silicon grease on the crystal gasket ring as well? Will this insure proper water resistance? Thanks.

I would think there was a risk if you used silicone on the compression ring. The ring and crystal are friction held in place, and I can't help but wonder if the silicone would allow the ring to be more slippery and risk having the crystal pop out of place if the watch was quite warm.

I have never seen anything written where silicone is recommended anywhere but on the o'rings, and Silicone is only used to lubricate and keep the o'rings supple, silicone does NOT seal the case this is a misconception, the o'rings and compression ring does the sealing.

I can't tell you how many watches I have seen with so much silicone packed in them it isn't even funny, all done in a misguided attempt to "seal" the watch and make it watertight. Caseback Silicone is a lubricant that's all, it's like K-Y personal lubricant, if the gap is too big, all the lubricant in the world isn't gonna fix it...or seal it... Use sparingly and only where recommended for best results

Thanks!

I haven't been using anything on the compression ring when I press the crystal back into the case but I just wanted to make sure I wasn't missing something.
