OTOOLWORLDO Ring Watch Back Gasket Rubber Seal Washers Set Watch Gaskets kit Replacement O-Rings for Watch Backs (0.6MM)

Do waste your money on gaskets from name brand watch companies, buy these for your case-back gaskets and save hundred of $$. For an SKX diver use a 31mm by 0.8mm thick gasket for the case-back. All case back gaskets on SKX SElKOs are 0.8mm thick and bezel gaskets are 0.7mm thick.

It was less expensive to get a whole kit than get one from a dealer. The o rings sized perfectly when measured with the caliper. Fit well and gave a water-tight seal. It would have been nice to be able to buy just the size I needed, but now I can replace O rings on a lot of watches.

I'm a watch collector and when replacing the battery in my Victorinox chrono the backplate gasket was torn. I ordered this gasket assortment set and the replacement 32mm worked like a charm. This assortment will come in handy since next I have a Movado and a couple other watches that will also need new gaskets. Great o-ring gasket set for your all your watch needs!

For battery replacement. If you dont replace the seal or "o" ring you are going to have a leak. One suggestion. Mens watches are larger and need a larger seal.. I haveuese them several more times, they work very well.

This is a nice selection of o-rings and the listed diameters seem to be true. I like to put a new seal in the backs of my watches when I change the batteries and these worked just fine.

It’s great to replace your watch batteries! But if the gasket is bad it’s nice to have gasket seals that work like OEM. Many sizes that fit most watches. You may want to buy various thicknesses depending on your watch model.

For a watch modder like myself it always great to extra case back gaskets.This little kits has all the major gauges.

Looks good quality but unusable for most of my need. Too thick. If your watches are not waterproof for more than 1 meter you are better off with the 0.5mm. The 0.7mm is too thick for the cheap watches that the cover will snap back out when closed. My first venture with gaskets and it cost me dearly, my mistake. Able to use on two watches so its not a total waste. Will buy again from the vendor my .5mm needs.
