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?

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...

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.

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?

      Oiling Dubois Depraz chrono module pivots (Omega Speedmaster Reduced)

      By Simeon · Posted

      Righty ho, I re-serviced the chrono module and got a reasonable result with minimal loss of amplitude when not running the chrono and about 30 degrees loss when running. Great. The problem is now that the chrono (and movement) stops running after about a minute or so, a tap on the watch starts it running again. No issues with the movement running when the chrono is stopped. Going to service it yet again, obviously some residual issues with friction in the chrono module (Very frustrating - I wish there was some way of testing it as I go!) I also seem to have a problem with the cannon pinion where the movement is running continuously (with the chrono stopped) but it's losing significant time / stopping. This is one of those two piece ETA style with a driving wheel pressed over the cannon pinion, obviously arranged for driving the chrono module. I had no issues with this prior to service and just added a small amount of grease between the driving wheel and the centre cannon pinion as the technical guide required. What's the best way of tightening these up? I would like to replace it but I guess this is going to be hard to find as it is dedicated to the DD chrono movement.

      He uses the micrometer cap, but he leaves the spring out (you can see that in the video). If you leave the spring in, the spindle will move up as well (as shown by @Knebo).

      Seems like he doesn't have the micrometer cap  attached to the spindle so he can only push down but cannot pull up? If the cap screws into the spindle I guess you don't need the spring? I only have a "normal" Seitz so I really have no idea.

      Lathe motor advice

      By Dell · Posted

      Yes in my opinion the 3/4HP is plenty but it’s your decision & yes it does come with speed control but foot operation so my reason for changing to potentiometer was because my leg shakes so it was like me revving the lathe & anyway I prefer to set the speed. I & a few others that I recommended the motor to run a Pultra 10mm lathe so if you have a 6 or 8mm B & L then it will be plenty, if you have seen any of my videos you will have seen that when using a graver I run quite slow without any problems.
