How do you remove the back of a Bulove watch to change the battery
There is a reason why Bulova watches cost so much when you need to replace the battery....it's DIFFICULT! You can try the following, but I would HIGHLY recommend having a jeweler replace it for you. At one time Walmart did it for next to nothing, but I don't know if they do Bulova watches at this time, but it costs nothing to call them.
Try this AT YOUR OWN RISK:
The best choice for removing a threaded caseback is to use a
"caseback removal tool", which consists of two or three adjustable
"pins" attached to a handle (most WalMarts sell a two-pin tool in their
jewelry department, and you can purchase a better three-pin tool from
several vendors on eBay). To use it, start by placing the watch
face-down on a padded surface (to avoid scratching the crystal). Adjust
the pins so that they very snugly fit into the notches cut into the
caseback; if you don't, the pins can jump out when you try to use it
and scratch the watch. Place the tool over the caseback and engage the
pins into the slots; then, holding the watch steady with one hand and
the tool in the other, give the tool a counterclockwise turn to loosen
the back (it may take a lot of force to do this, especially if this is
the first time the battery is being replaced). Once the caseback is
loosened (usually about 1/4 to 1/2 turn), remove the tool and finish
unscrewing the back by hand to avoid scratching the watch. Be careful
as you remove it as some watches use a very thin O-ring on the back to
make a watertight seal.
Afer replacing the battery and ensuring the watch is running
properly again, carefully inspect the surface of the case and the
threading on the caseback and remove any dust or grimy deposits with a
soft cloth. Then, place the caseback onto the case, being careful to
align the O-ring or other seals, as well as the caseback threads (tip:
to ensure the threads are lined up, place the back on the watch and
turn it counterclockwise about 1/2 turn or until you feel the ends of
the threads "fall" into place). Screw the caseback down as far as
possible by hand, then use the removal tool to tighten it the rest of
the way.
