Too much rotor wobble for this Tissot cal. 784-1?


Recommended Posts

Hello everyone!

So I'm new to this forum and first of all, thanks for having me here! I'm also new to vintage watches and recently got a vintage Tissot Visodate with cal. 784-1. The whole automatic works was replaced—probably with one from cal. 2571, 2481 or something similar, judging by the color—but I still feel that it has too much wobble and wear on either the arbor or rotor bushing. The video in the link shows how much rubbing sound the rotor makes and how much wobble it has. I'd appreciate it if anyone could tell me whether this is acceptable for such a watch that will be worn daily or not.

Thanks Andy. You're also correct about the rubbing sound, though the seller will take responsibility for a proper fix.

That said, do you think $170 is a good deal for this watch? Other than the automatic works the movement is in good condition, and the seller has promised to fix any issues but probably it won't be the original cal. 784 rotor and automatic assembly in the end.

Also the case has been polished but it was done right and clean. The dial is also very clean, except for the slight fading of the "UT" in Automatic and "E" in Seastar; plus only 4-5 indexes have their original lume dots. The hands on the other hand have a few scratches and their lume is gone.

I think that's a good deal for a nice watch like this.

I once serviced this calibre and ended up buying 3 or 4 rotors until I got one that didn't wobble too much. Quite a tricky one. A little rotor play, however, seems to be normal on this calibre. But yours has clearly too much. 

Where are you located?

That's very reassuring to hear, thanks. It really is a gorgeous watch and I really like the curved silver/beige dial, it has so much depth and character.

Well I already sent the video to the seller and they agreed to a fix free of charge. We are located in Iran so getting replacement parts is a bit tricky but donor parts are available, and hopefully they can fix it properly. Here we're reaching the end of the year, and with all the rush I guess it was just an honest mistake while servicing the watch.

It will be either the axel or weight, neither are that expensive.

I just examined both the weight bushing and the axle, and I think the problem is with axel rather than the weight. Am I right? Nonetheless, hopefully the fix works out just fine with good donor parts.

Here are the pictures of the weight bushing and axle under the loupe:

Yes I'd say the axel is most likely and the parts I've shown are new, not donor.

    • HWGIKE#57 Valex FEF 190 15 jewels Swiss lever full service and repair This one was waiting for a balance staff replacement in my cabinet parts and case cleaned up with a new balance staff and a 4th wheel as the original 4th wheel had a broken pivot for the off center second hand. I never attempted a balance staff replacement before however I received a Bergeon Molfres (i was hunting it for about 2 years) and with the help of it I managed to remove the old staff and riveted the new one in. It also received a new MS, crystal and the hole for the MS arbor was also tightened. With the new MS now it has an acceptable performance meaning that the amplitude goes up to 280 fully wound, has an acceptable beat error and I have the two nice lines but only dial up, dial down is not as nice and I could not figure out as why. I have the two lines but the amplitude is dropping to around 230 and the lines are a bit hairy. Both dial up and dial down the lines just go up and down without seemingly any pattern. I cleaned the movement two times, and then a 3rd time pegged out the main plate and train bridge holes but made no change. Both the HS collet and the roller table was too lose on the new staff... I did not count how many times I took the balance cock off to sort out the HS collet, the roller table and the beat error, somebody before me also shortened the HS by pushing it out a bit and it seems every time somebody is messing with the end of the HS the protruding bit is most of the time twisted bent etc. This one was probably one of the most challenging repair and service. I might take the new MS out and clean it lubricate it as I just pushed the new one in to the barrel from the retaining ring. Plus started to re-read the theory of the escapement and how to analyse the graph on the timing machine: Greiner Chronografic Record manual. I am also thinking to put the watch on a 24 hour long run with the eTimer SW it once helped me to figure out what was wrong with a watch. There is an interesting part of the Greiner record manual talking about the pallets and the end shake of the balance and pallet staff. Maybe this is my issue? Who could that possibly identify? After a few years now I am still without a clue how could watchmakers make parts I can only see with my microscope or how could/can they carry out complicated services impossible to do.. real magic..... .... ..... before I sent this post while the pics were uploading I had an idea, i was browsing the possible outcomes on the timing machine I had one for magnetism..... so I demagnetized the movement and it is not hairy now.... two really nice lines 0.2 ms beat error still a bit wavy, but a lot lot better..... argh....  
    • Hi there, welcome here.  
    • yes the advertising revenue should generate money. The question is how much money? Then as far as the cost of the website goes that's relatively easy to determine? all you would have to do to grasp costs and profitability would be to go to the link below and you can actually get a website for free try it out for free I believe you get no advertising initially. They also talk about that they'll help you out they have marketing tools and some sort of paid subscription or something. So I guess were shopping for a whatever just ask them what would a maybe could use this one as an example in other words it's going to look basically identical to this is going to have advertising a paid subscriptions what's it going to cost? After all they want to sell or give us a message board like this they should bill answer the questions as they're the people who did the software for this. Yes they really said you can have a free discussion group at least to start. https://invisioncommunity.com/ I was curious about the monthly supporter thing where exactly do we find that on this message board? A quick search I'm not finding it so obviously I'm not looking in the right place?
    • Help me out here, but with all the advertising on this site (which I don't mind) wouldn't it pay for itself or even make money for the owner ???
