Is this possible / practicable? Watch in question is a Parnis sub-clone. Is it just a case of fitting some decent gaskets and replacing the crystal (which I suspect is a bad fit) or would more be needed?
What's it currently rated to?
It is possible but don't expect a very high water resistance.
If the glass doesn't have a gasket a plastic one can be added and it should help although it can be a bit complicated since the glass will sit a bit higher on the case, then again one could simply order a slightly thinner glass. It also depends on whether the case allows the installing of a gasket or not but most do...
I'm guessing it already has a screw down case back so if it doesn't have a rubber gasket one can be added so that's that.
It's a bit more complicated with the crown which is probably not screw in. You could give it SOME water resistance by adding a rubber gasket but such crowns have special indentations/slots for the gasket to be fit, then again the watch might already have a crown gasket or two (a gasket can also sit inside the crown, for some designs) if it has a rating of at least 100m.
Easier, cheaper, quicker to buy a WR watch!!! Millions are available at bargain prices in every conceivable style...
Have to disagree with some of the advice.
There are two scenarios: a watch may have been designed to be water-resistant but owing to deterioration is now leaking. In principle this is fixable.
Secondly, if the watch hasn`t been designed to have any water resistance it's not feasible to modify it successfully. This depends on the design, but what I`m saying is generally true.
As for crowns, water resistance can be achieved without a screw-down crown....lets be clear about that point.
As a Sub-homage this watch has been designed to be water-resistant, in which case it's all about replacing seals and ensuring everything's fitting together correctly. That's entirely feasible and I`d expect most repairers to be willing to do it, or at least try. However, if this involves trying to source generic seals it can become a real pain......try finding the correct size of O ring for a crown! Unless someone has a big stock and is prepared to spend time finding one that'll work it becomes difficult.
If the glass doesn`t fit correctly that's probably where the problem lies, but why doesn`t it fit correctly? Has someone messed with it in the past and replaced it?
You don`t state whether the watch is new or recent etc........the better the info given the better the quality of the replies! Water resistance is a bbit like being pregnant, it either is or it isn`t; the rating is merely indicates what use it'll stand up to. A watch with 300m QWR has ZERO WR if a seal's damaged!

A cheaply made watch that looks like a diver, but wasn’t intended to be waterproof/resistant isn’t going to benefit much from some quality new seals. Maybe some bathroom sealant liberally applied all,over might over some resistance, but it will most like leak like a....
It's just a matter of time...
I’ve never handled one of these but I’d expect the design to confer some water resistance.
They potentially leak from 3 places, that’s the glass, crown and caseback. Even at this price I find it hard to believe the watch isn’t designed to seal. It’s possible the watch is leaking down the pendant tube where it fits into the case, but this is quite rare.
With regards the screw down caseback a quick fix would be to PTFE the caseback threads tho not recommended as a long term fix.
With regards the crystal, if you need a custom machined water resistant i gasket making let me know.

Couple of quick iPhone pics which hopefully show what i mean. Look at the difference between the two, there's definitely a gap between caseback and case on the 2nd IMO. This is exactly how it came from Parnis.

Perhaps an over thick o ring OR either not fully tightened down or threads not fully cut.
Maybe I’ve missed a trick here........but has the watch actually leaked yet?
100% not worth the effort.
When you look long into an abyss, the abyss looks long into you.........
It depends on the level or WR you are seeking as dynamic and static WR are two different considerations.
For moderate swimming, you might be able to get by encapsulating your watch in hot sealing wax. Not recommended if you are going to go scuba diving or taking a plunge off an Olympic-sanctioned high dive platform.
Do you know, I've never even considered the hot sealing wax before. I must see if my local AD can offer the service before my next trip to the pool.
It's just a matter of time...
Probably cheaper to just set asides funds for a new one when you drown it... can't imagine you can get away with just bodging a waterproofing without a whole redesign.
No!!
Nothing wrong with the design, the watch has a fault with the sealing! This should be fixable but it needs to go to a repairer to sort it out and then it'll have some water resistance......and trust me any is a whole lot better than none!.
