xihongshiWatch Waterproof Sealer Round Black Sealing Gaskets Portable Waterproof Grease Watch Repair Tool for Watches Repair Watchmaking Supplies

Great product, easy to use for any watch building hobbies.Good value and fast delivery.

Perfect for the job

I use it to lubricate watch "O" rings and it is very good.

Plenty of silicone grease inside.

Misleading description of the amount of silicon grease supplied. It's all sponge , and very little grease! MQ

Used to seal the back of a watch and 6 months later. It works!

Hard to know really until next time I'm changing the watch battery but seems like this will do the job.

Seems to be a good amount of grease in the tub, unfortunately there was grease on the outside of the tub as well. Not a disaster after a good wipe. Also the glue in the lid that should have stuck to the pad had not, so it's impossible to turn the pad to rub on the grease.
