JB Weld will fix anything.

Other than traffic tickets, that is.  JB Weld has clear ethical standards!

For something a trifle less permanent than epoxy... I'd simply replace
the gasket.  The instructions which came with my watch recommend
replacing the rear-plate O-ring gasket periodically (every few
years)... I imagine that the elastomer compresses, and becomes less
resilient with age, and thus doesn't seal as well.

Take it apart,clean the gasket,and its mating surfaces,and smear a
*small* amount of Vaseline/petroleum jelly on it,and reassemble.
Usually works for me.

If the gasket is natural rubber (and perhaps even "synthetic"), Vaseline
will dissolve it. Anyone who uses a certain product found in pharmacies
knows this.

I wondered whether the original post were a troll, as it's hard to
understand how the poster would be aware the watch was leaking, without it
having been inundated with water.

LOL  !!!!

You can use a silicone grease (NOT a sealant), available at your local hardware
or home improvement center.  Just squeeze a dab onto your finger, then
thoroughly coat the gasket (O-ring) with the silicone. Reassemble the watch.
That should keep moisture out.  Make sure that the gasket is seated into its
groove and tighten the screws holding the back on the case well...

Having read the answers (as of 10:30am CDT), I'm still wondering as
well.  Nobody covered anything other than digital watches, which are
fairly easy to seal.  I have several analog units which
leak--presumably--around the stem.  I wonder if there is 'any' hope for
these, as several were pretty expensive when new.  I suppose a jeweler
would have some sort of solution; but I paid less for any of these than
the trip to the jeweler would cost.

I was hoping for a DIY solution.....

For simple leaks I use silicone grease. Silicone high vacuum greese is
real thick.

Most use an O-ring under the stem. However, if the watch is worth
fixing, it is probably worth fixing right...

Try some silicone sealer (similar to silicone dielectric grease, but
*much* thicker). That may make them more water *resistant*. You'll
never, ever, make them waterproof without some serious work.

Buy a new 10$ watch , remove the gaskets and put them in your prize
watch .

I'll give the silicone a try.  Despite the presence of a good back
gasket, one of these will fog up from a good sweat.  Never mind actual
immersion.  Getting caught in the rain is occasion to open it up and dry
it out.

Thanks,

What's it leaking?

When opening the watch case, jeweller is supposed to change the gasket.
Then he does a pressure test to make sure that the watch is water proof.
Sometimes the pushers and crown (buttons and winder) gaskets have to also be
changed.
