Does its job perfectly. It’s easy to store and use. For its price, can’t complain.

So far, this has worked extremely well in my applications. Simple design is as easy to use as to just drop the watch seal into it and then close it up - set it aside as you finish your work.It's silicone lubricant is like a thick oil, light grease. It gets those seals all wet, sticky and well covered before you send the watch into the press to seal your pop-lids.It's slippery, sticky stuff - it stays put even when you re-seal a screw back case watch.It simplifies closing up watches due to the lubrication it provides, no pinched seal - even if old and a little dry.New seals just slip together in case backs without a second thought.I couldn't ask for more.It's of a generous size and quantity of lubricant that you can see "pooling" in the bottom half. It's size is such that even the most monstrous wristwatch seal can be treated before installation.The goopiness of the silicon oil also helps preserve water resist watches' integrity if exposed to water. By insuring the seals are conditioned and, the extra layer of silicon helps ensure the seal goes in straight and true.

Ther isn't much to say outside that it made well and does the job, which is to lubricate watch O-rings. It's reasonably well made of good materials. I would definitely recommend.

Product seems ok and as described and expected but, since I've not used it yet, I can't say much else. It was as described and arrived on time.

Anyone who does their own watch battery changes or a jeweler should definitely have this it makes putting that rubber o-ring on so drastically easier

Easy to use, I use it on watch back seals. Good value for the money.

A lot of the grease leaked out making a mess and there seems to be less on the pad inside. Also, the pad came unstuck from the top. The whole point is to be able to rotate the pad using the top to apply the grease so this was useless and got thrown away.

This stuff is great! I used it sealing up a Luminox dive watch as soon as it arrived. Thanks!
