In this video I use my new Seitz Jeweling tool to replace a jewel on one of the plates. The reason for this is I purchased a new ratchet wheel and the pivots were too big for the existing jewel. This watch is a very nice Chinese Clone so not all the parts are to ETA spec. Grinding down the pivots was not an option so I mined 50 Russian watch movements for the right jewels. Found the first one in 20 min and replaced the jewel. The second one on the main plate took two hours to find as I looked at and disassembled many watches. Here is my video for anyone who try this out. First time using this tool as well.

Had to strip down the movement again to get the plate out with the other jewel to replace9f9c5cf32bda1ba240ef2c1b285292b4.jpgd2285217237897524afcb2cd3a362e78.jpg
Here is the plate with the old (too small) jewel on the upper left and the new (Russian watch) jewel on the left. Next step is to clean the jewel and plate hole and then press in the jewel.

      L&R Varimatic Needs Adjustment

      By clockboy · Posted

      Welcome to the forum, enjoy. I have a varimatic that went  out of sequence because it’s hydronic oil ran very low. Must admit it’s still in my garage just know time to fix it. Purchased a cheap Indian Junta/ sonic Pearl as a stop gap a few years ago and it still performs perfectly so no incentive to fix the Varimatic.

      Is this a 'hack' ?

      By dnhb · Posted

      The plate is OK, thanks. It seems the answer to my question is that this is a 'hack' & for me another reminder that in general, one won't be the first person to be tinkering with an old timepiece!. As you day, I've been fortunate to have gotten some good advice and, just as important, encouragement. I've been lucky then not to have the balance spring break as a result of my novice 'ministrations' - but I did remember to 'stroke' rather than bend per se. The clock is of sentimental value to the owner so I'm relieved to have now got it running to time with the support & encourage of forum members like yourself.

      L&R Varimatic Needs Adjustment

      By storminwestie · Posted

      Recently purchased a L&R Varimatic knowing that the piston does not fully rise in the cylinder. The likely cause is air in the system. The manual calls for using a bleeder cup, which is as rare as hen's teeth.Does anyone have any experience with this issue and if so, how did they resolve it?
