Thank you for contacting FixYa.
If you have a good quality scuba dive watch that needs to be repaired, such as needing a battery replacement, it can be tempting to do it yourself. After all, don't you just need a screwdriver, a battery and rubber gasket (possibly)?
Well, yes. But if you do it yourself, you run the risk of voiding the warranty.
So if you change it yourself and the watch later floods, you are out of luck. So check your warranty information carefully before you attempt to do anything yourself or have someone other than the manufacturer/authorized dealer do the work.
If the manufacturer changes the batteries or does any other dive watch repair, they will normally retest the watch and certify that it is still water resistant to whatever level applies.
This is not to say that a qualified watch repair shop can't do the job. It's your decision but at least it will be an informed one.
So the long and short of dive watch repair - if it's a good dive watch, you'll probably want the manufacturer/authorized dealer to handle it if you don't want to void the warranty. A cheap dive watch? Probably not worth the bother.

4 months is pretty poor. Jacque Lemans is not a very good brand, I would stop throwing more money at it. Put it down to experience and get another watch. Many many good brands out there, you don't have to spend a fortune. Seiko for instance make quality watches throughout the price range from $50 to $50k!

Gently pull on the "knob" on the side of the watch. You may have to get your fingernails between the watch edge and the knob. It will pull out a little bit, then a little more. One position will change the time. The other position will change the date (if it has a date function) If it has multiple knobs/buttons, it is typically the one on the right side that doesn't have smooth edges.
