Rotary Quartz, what movement is this?


Go to solution Solved by JohnR725,

Question

Hi, trying to sort this Rotary quartz GB02298/18. Can't see any damage but the coil appears to be dead. Stripped it down a bit in the hope I would find other markings but all I have is Ronda 1 jewel, so looking for some help to source a replacement movement or parts. Does anyone know what movement it is likely to be or where I can find out?

So at least with Ronda they have technical information on the website. Then for identifying the watch it would be nice to have the rest of the watch in the picture and specifications like the diameter. Because different size movements will still look similar. For instance the first two links they both look similar except the second one is the correct battery which is conveniently located on the back of the case. Third link in case it's not one of these two.

Is this a Ronda 515 ? Sure looks like one...

By the way, if you don't manage to find this exact one (in case it's something other than a 515) ETA/Ronda make modern day equivalents of older movements so you should be able to find that one...

Hi guys, with your help I have now managed to identify the movement... it is a Ronda 705. Now I just need to make sure I get the right height. There appears to be 3 different heights that might work, 0.60, 0.75, 0.95 (all very close)! On Cousins they are referring to "Hour Wheel Height Over Dial Seat" Am I right in thinking this is the height of the centre brass section that protrudes from the movement in my picture? If so, what is the best tool for accurately measuring that height?

    • Thanks🙂 so much I just got your reply so I will let you know. 
    • Hi there Mr jdrichard, glad you have these holders. You can also apply pressure on stubborn screws and the Myers won't let the movement flip of the holder and the whole show end on your bench. Also keep well lubricated both holders.

    • Hi All, Just am update.  I have received the donor movement and took the couple of parts I needed before I started my attempt on the dial side.    I believe I am missing 3 parts.  See photos.  If anyone has them as spares, please let me know.  I am not sure the ‘Dial Rest’ part is needed for mine as it was not on the dial.  It’s big enough for not to be missed etc but I may take it if available.    Regards, Yasser.
    • if the case back is not original you're definitely going to have a problem. Usually when ordering components for cases for Seiko watches everything is based on the case back number. It could be a different case back as long as it's the right case back for that case then you could use the number. But if it's totally wrong case back here in trouble sort of? If you look at the dial usually on the bottom there is a dial number it's not exactly the same as the case number. But it helps to narrow down the range of what you're looking for. They is probably I was Seiko is that they've made so many case components. They haven't old it's been discontinued desk of even a bigger problem.  I know their sites out there were people are modifying their Seiko watches if you can find one of those sites may be they of something generic.
