    Help With Opening Watch Case

    Hello folks I have my dad's old Tarleton mechanical watch that doesn't seem to be working and he said I could tinker with the internals. However, I can't seem to get the caseback open. There are no notches for a jaxa wrench and it isn't a pop-off back. I did notice little notches on the back of the watch where a tool might fit-- is there a specific tool for this type of caseback? Thanks.

    Try using a sticky ball or make a sticky tape ball

    Do you know a good place to get a sticky ball from? I've heard of people buying some before that don't work well. I will also try the sticky tape ball.

    Funny enough, I found one at Walmart one time, but only because I had seen them on eBay. That's all I got really. Good luck

    I've used duct tape to open a couple of watches. Worked suprisingly well actually.

    OP, I have to say I'm a little concerned with you tinkering with the movement. Just saying its a bit more complicated than the case back that's giving you problems.

    But, I'll help, if it is a screw back and developed a bit of rust, spray it with WD40, or soak the edges with oil. Than you duct tape the jaws of your channel lock pliers and while holding the watch at the lugs with your hand carefully use the pliers to twist off the case back. This method has worked without damaging the case on a bunch old watches.

    Good luck.

    And you'll need the tip that looks like this.



    Good luck.

    It's like a Breitling back right?

    It is similar, except the beveled edge on that Breitling is on the very edge of the case back, while on this Tarleton it's a bit more inward.

    Also to the previous poster who was concerned about my tinkering, this watch is pretty much toast and ready for dissection!

    If you're not used to working on watches, make sure you're careful, especially with the mainspring. If you open the barrel the spring can eject and actually cause injury. From Wikipedia :

    Hazards

    The mainspring contains a lot of energy. Clocks and watches have to be disassembled periodically for maintenance and repair, and if precautions are not taken the spring can release suddenly, causing serious injury. Mainsprings are 'let down' gently before servicing, by pulling the click back while holding the winding key, allowing the spring to slowly unwind. However, even in their 'let down' state, mainsprings contain dangerous residual tension. Watchmakers and clockmakers use a tool called a "mainspring winder" to safely install and remove them. Large mainsprings in clocks are immobilized by "mainspring clamps" before removal.
