Ronda 715 Coil


Recommended Posts

i would like to test the coli on the Ronda 715 movement. Could anyone help here please? Can I check the coil in the watch, or is it best out of the watch? Can I use a digital multimeter, if so how? Have read somewhere that an analogue meter would be much better, but have only got a digital.

Just need to know if the coil is working properly.

Any hep would be really appreciated. Thank you!

An analogue meter may have been suggested as some digital units can pass a reasonable amount of current out when testing. I'd say it's preferable, but I've always used my digital.

I'm not familiar with the 715, I would expect you'll be able to tell at least if it's open circuit or short circuit. If you can find a spec / service sheet, then it may state the nominal resistance of the coil.

Most DMMs are simple.

    • That's the right technique Mal đź‘Ť If you are ok with a loupe ( which I'm not ) then pick up the dial in your left hand and make a tripod holder out of 3 fingers and then exactly how Mal and me described with your right hand, press and flick out the stem at the same time. You need three fingers to do this, i use my ring ring finger , sounds like mal uses his little finger, just whatever you feel comfortable with. The key point and dangerous side to this is the tweezers or driver slipping off the release screw. Stablise your left arm by resting your elbow on your bench, so that you can hold the movement horizontally flat, use a x5 loupe to view  and good light so you can see well and have a good tight fitting screwdriver to push the release down. Or as suggested a pusher mounted solid upside-down somewhere then all you need to do is push your movement up to it. I'll rig something up in a bit to show you what i mean.
    • Thanks Michael, shes a real soldier, it would take a tank to knock her off her feet.  Shes surprised even me and i knew she was a tough cookie.  Good for you Michael, you keep at it. I've been reading your posts re. your watchroom they're inspiring and it doesn't matter how long it takes you to get there its about the journey. Rome wasn't built in a day, our watchcaves are our solitudes, our own little empires where we can shut ourselves away from the crap that goes on around us in the world. I look forward to seeing you progress, I have my own ideas how i like to do things. But in answer to your questions on that thread, just let your workspace evolve around you and how you work. You wont figure it out straight away but you will know when to change it and when to leave it alone. But most of all just enjoy it.
    • That can be tricky. Sometimes I hold the movement from the edges in left hand and with right hand I push the release with tweezers and simultaneously pull the stem out with right hand pinky or something. 
    • I see what you mean. I must admit I’m not entirely comfortable with that but I can’t see a better method than what you suggest. I’d like to see something like this mirror with a short spike: https://www.cousinsuk.com/product/mirror-for-observing-movements Place it on, push the spike on the post with one hand and release the stem with the other hand. Minor problem, it doesn’t exist.
    • Hope you mum keeps on mending. I was adamant that I was going to get myself going after my stroke. I was only 52. I still have a lot of life left to live. Some people give up. Some people don't let it beat them. Your mum sounds like one of the winners. 👍
