Do I really need Sealing Grease dedicated for watch gaskets?

[VWatchie]

I’m running low on silicone grease and wonder if I could use the contents of this tube instead of ordering silicone grease specifically marketed for rubber gaskets in watches. The substance in the tube is transparent and resembles, for example, Bergeon’s Silicon 7 Sealing Grease but is somewhat “stickier” in consistency. I use it to seal the rubber gasket around the water traps in my home. The price is a really big difference, at least on the surface. Bergeon’s silicone grease costs almost 40 times as much per gram.

It's marketed like this:

• Clear transparent, with silicone lubrication
• Lubricating grease and sealant for O-rings and drinking water fittings
• Hot and cold, -40°C to +200°C
• Food-grade quality

Am I taking any obvious risks or do you see any disadvantages?

I can't see any problem with using it for case back gaskets.

I can't see any reason not to use it either.

You're A-OK with that. I use Molykote 111 that I bought ages ago to use on a lever espresso machine.

Wow, that was unexpected considering the huge price difference!
