Change a Watch Battery Without Tools




About: I'm an Industrial Designer. Me loves every kinds of engineering and creativity that the human can come up with.

For this instructable, I inspired myself of all those watches battery changing tutorials videos because they all have a tool in comon : The screwdriver for watches. I thought that it was useless to buy that tool.

All you need is :

-a watch with a back you can unscrew ( like in the picture )

-a pair of scissors

-a wire (a pin)

-not a new battery, you don't know the battery number yet, (they are not all the same)

Step 1: Open the Bracelet

#1 Open the bracelet

At the end of the attachment of the bracelet, there are some little holes,
you need to push on the telescopic pin that assembles the 2 parts.

Take your wire and insert it.

Step 2: Unscrew the Back

2# Unscrew the back

Put your scissors ilke in the picture below. Push hard on it and turn counter clock wise.

Step 3: Take Off the Battery

3# Take off the battery

Take your wire and slide it gently under the battery. Pop it out.

Take a look at the battery and take in note the serial number. Go buy it, put the battery with the positive side up and put everything back.

There you go.

    I am researching for methods to change batteries on a watch. Would like to thank you for this piece. It is really good. However, you have used some tools in your tutorial. but since they pins and scissors are in everyone's home, making your way easy

    I shall be writing a post in the same topic. and would love to feature your guide on it..

    If you could replace the battery without the use of a safety pin and scissors, only then could you claim that it was done "without tools".

    To prevent fogging glass from inside after home battery changing I heat watch while open. Then still hot I close it. When reaching room temperature I am preatty sure inside is less humidity.

    Thank you, your instructions saved me a lot.


    Ok your watch is a chronograph the little sticker on the back talks about zeroing out the watch out when you change the battery, you need to touch the AC to the power to do this. Also make sure you use a watch battery with a W at the end like a SR920W since that looks like what your battery is, since it is made for the high drain of the chronograph. The SR920SW version is made for non-chronograph watches. Any other questions just ask.

    NP if your watch is water resistant to 50 meters / 160feet or more let me know and we can discuss ways to maintain the WR when you change your battery. The watch may also have a rating in ATM or BARS, so anything above 5ATM or 5BAR would need a little extra work to maintian the WR.

    hecks yea nice...simple. one thing though...u forgot to mention normally theres symbols telling u which way to push the pin through. do it the wrong way and u make em useless
