200 Fluid Pure Silicone Oil Polydimethylsiloxane (PDMS) 50 centistokes (CST) Viscosity, 4oz Bottle

Works great with watches. Filled a casio dive watch 2 years ago and it been great.

I hydro modded my watch and it works ok and looks amazing in real life, however The hands are off and can’t seem to know where to go back to when moved for other functions, I can live with it though. It’s hard to keep bubbles out when modding, I found tapping the back plate before screwing it down helped work out some bubbles. Good luck!

Tried it for hydro mod on watch, pretty good quality

I used this product to hydro-mod my watch. It worked perfectly. The time can now be read when the watch is at an extreme angle, and it has had a negligible effect on accuracy. If you are hydro-modding, I highly recommend this oil. I have no opinion regarding its actual intended use.

Great, and a good amount. Already did 4 watches and looks very clear.

I bought it for some research work in my lab but since it did not arrive on time, i could not use it for that purpose. However, i used it on the wheels of my baby's stroller since it was make loud noise. And Voila! it worked like a charm. I am impressed by this.

I've hydromodded two watches. I'm happy with results.

Excellent for hydro mod on watches

Filled two Casio watches. Perfect viscosity. Pour the whole thing into a small bowl and assembled while immersed, no bubbles. You’re now good to dive (or just press the buttons while in a hot tub).

Je connais ce produit et j'ai voulu m'en rateter
