WHAT SIZE BATTERY DOES A RELIC WATCH ZR15402 TAKE?

SOURCE: Watch Band Adjustment

I just got this watch for a gift and was able to remove links myself after doing some research. It really isn't difficult if you are patient, have a little mechanical experience, and have some very basic "tools" available.

Tools:

• 1 push pin like you use on bulletin boards with a plastic head
• 1 small hammer like a tack hammer
• 1 pair of small pliers. Needle nose pliers would be best but I used diagonal wire cutters (be careful not to cut the link pin)
• 1 small block of wood

Try to pick a well lit table in a room where you will not be interrupted.

Procedure:
1. Lay the watch and band sideways on the block of wood so that a pin for the link you would like to remove is just hanging over the edge of the block and pointing down. You need the block to brace the band while you hammer lightly on the pin. Someone to hold the watch in that position would be helpful, but it can be done alone. Only try to remove pins that have an arrow on the back of the band pointing at them. It does not matter with this watch band which way you go with the pin.
2. Carefully line up the push pin point with the top of the pin.
3. Slowly, lightly and carefully hammer the plastic side of the push pin so that the pin in the link just emerges from the band on the bottom side enough so that you can grab it with the small pliers.
4. Slowly and carefully pull the pin straight out with the pliers. You can pick up the watch from the block of wood to get a better grip. Be careful not to bend the pin since you will need to replace at least one of the pins you remove.
5. Repeat steps 1 - 4 until the band is the correct length. I needed to take out 3 so I removed 2 from one side and 1 from the other side of the clasp.
6. To fasten the watch back together again, gently insert the pin back in the hole it came from it. You will probably need to use the tack hammer to make the top of the pin flush with the band.

OK basically there must be an element that you can push out in the direction of the arrow. Either there is a very thin pin (like a needle) that you can push out with a blunt sewing needle (break the tip), or there is a more sophisticated system as it is shown under the following link:

If this is screwback, then there should be grooves for inserting case opener claws. For this yoy need case opener with interchangeable claws. You can buy it on ebay for approx. £7.00.
If the casebask is snap-on, then there shouldn't be any grooves, just small opening (lip) between the caseback and case. This is exact point where the watchmakers knife blade must be inserted and pryed up.
Do not forget to rate, please.

I suggest that your watch has an oxidized contacts and electricity can not reach the movement.
Do as folloes:
Take out the batttery,
Clean (scrape) all battery related contacts till they are shiny (use hardened steel needle for that),
Use the dust blower to get rid off any tiny dust and dirt particles after cleaning,
Refit the battery back.
Now your watch should work again.
If all written above do not help, then there is a problem with your watch and you will need the help of the watchmaker.
