I have a watch from the NRA it is called Ridgeline YUKON. I need to change the battery but cant figure out how to take the back off the case.

The Proper way is with a "watch case wrench". They can be purchased for a few dollars on Amazon and E-bay. In most cases unless you are changing many watch batteries the best option is to call around to local jewelers and pawn shops and ask how much to replace a watch battery. In my town it ranges from $30 to as little as $5.99 battery included.

mcdevito75 here, If the back screws down, you"ll see a series of square holes around the edge of the back cover, in this case you"ll need a special tool called a case back remover tool to un-screw the back cover. If there are no square holes on the back cover, most likely it"s a press type back cover and some of these cavers are very hard to get back on wothout another tool called a case back press tool, these mentioned tools are available on ebay, but, with just a battery replacement, the time and tools you may need the cost is more than a watch repair shop would charge you. Best Bet, look for a small watch repair shop in your area for this once a year or even longer battery change.

Thank you for contacting FixYa.

Place the tip of your pocket knife in the slot on the back of the watch. Pry the back off.

Take your tweezers and grasp the metal piece that is hiding the battery.

Once that metal piece is out the battery should come out too.

Put the new battery in and cover it with the metal piece.

Put the back of the watch back on and snap it into place.

Best wishes. Jewel

mcdevito75 Here, I would figure a specific glue to reattach the back cover. Vicence watch is in italy, I have an email address, info @vicence.it Also, from a web search, Lawson Watch.com tel. # 866-805-0007 They may be able to help.

There is a small groove between watch case and case back. This is the place where to insert the openers blade and pry up.

Some backs pop off with a watch case opener or knife. Other case backs are removed with a special wrench which all watchmakers use routinely Take this to a watchmaker close to where you reside.

If you have any further questions please let me know.
Many thanks!

If it don't tick I can fix

Generally Diesel uses a pop off back. The pop off back will be smooth and have no indication of how to come off.

To remove a pop off back use a watch knife and press it straight into the separation between the case and back. Start at the upper right corner. Do not use a sharp knife or widdle back and forth as this may damage the surface where the seal is or make burrs. Once you have driven the knife straight in you can move around the back repeating this until the back is completely off.

Manual doesn't help. I changed the battery but the watch is still not powering up.

DONT try to change a watch battery yourself unless you have crystal press to close it and thats if the case back pops off...if it screws on then you need a case wrench to open and close it! Better to seek out a local watch repair business and avoid Walmart! :-P They arent trained to repair watches...Ive fixed a lot of their mistakes!
