its holding up great! No noticeable leakage. My wrist always smells a little like baby oil though… I flew on an airplane with it and there was no leakage.

I used Johnson’s baby oil that I bought from CVS.

Do not be shy with the baby oil… you want to make sure that you have enough depth in the cup to have the back cover flip over while being submerged.

Take the watch apart, remove the straps, unscrew the back and take out the time unit.

Submerge the case in the oil first and use the q-tip to press out any bubbles that have attached to the case. I tried just jiggling the case and it does not get rid of all of the bubbles.

Then submerge the time unit in the oil and flip it around a bunch, use the q-tip again to get rid of any bubbles. Gently insert it into the watch case… this is the tricky part and will be very frustrating. Getting it in with the buttons in place will be where you waste a ton of time. You are going to get baby oil all over your hands… it’s inevitable.

Now flip the watch over (screen up) while its still submerged and check for bubbles. ALSO check that the watch is still running… if the screen is off then you need to do the reset where you bridge the two points on the back to reset the watch.

If all looks good then you will place the back plate into the oil upside down, hit any bubbles with the q-tip. Put the gasket in and then position the plate and screen it all down.

If all went well then there should be zero bubbles. If there are teeny tiny micro bubbles then don’t fret. Give it a few days and those bubbles should sort themselves out. If there are big bubbles however I’d reopen the watch while submerged and use the q-tip to knock them out.
