Timegrapher information

Question

Hi guys, I just serviced this Rodana. Amplitude seems good, however no matter what I do to the regulation arm the timegrapher keeps showing ++++s/d.

What is that due to?

It’s not a timegrapher issue, as it works perfectly with other watches.

Thanks for your help!

What is the movement? 

Also does your TG auto detect the beat rate or have you set it manually? In which case have you selected the correct value?

My TG detects the beat automatically.
Here is a movement shot. It’s marked AS 1297
1294

Also, I don't know what you did to the balance and cock, but make certain the HS is between the regluator pins.  BTDT! 

I have also seen a HS catch on the upper level of the balance cock, so give the HS a good look under magnification.

 

Good Luck.

It has picked up the correct beat rate then (always worth checking) but the +++++++ display means that the rate is fast by a large enough margin to be out of the display range.

As already suggested the H/S could well be touching somewhere that it shouldn't. You could also have coils sticking together either because they are magnetised or they a contaminated. These would be the first things that I would look at.

I’ll start checking out the HS. To be honest I had a hard time setting the balance jewel into the pallet fork due to where the balance is, so I may well be done something wrong on the HS. I’ll come back after checking that out!

In my experience Weishi machines detect beat rate accurately. If is says, as it happens here, 18,000 and way fast (more than 1,000 s/day) that it means the next auto rate of 19,800 (10% faster) is not applicable. Assume the algorithm threshold to decide rate is at midpoint, that is 4320 secs a day, or 72 minutes, that is not credible for a mov.t running slow.

I can say that even if the lines came to an almost straight pattern which usually comes with +-0 spd the reading stays at ++++ s/d.
The lines also get up and down continously, they’re not able to stay straight.
Hope I explained it well enough

That is typical of an hairspring rubbing. 


And you were damn right!
The hairspring was rubbing between the pins.
These are the new readings! Have to say I’m happy. Just have to set the watch in beat now.
Thank you so much to all of you guys for your help :)

I recommend to use the browser on mobile devices. Forum software has excellent support for these, so that all features can be easily accessed. I've stopped using Tapatalk after realizing how limited, slow and awkward is.

    • I cleaned it by soaking in Home Depot naptha and pegging by hand, 2 rinses. Demagnetized the whole thing, as well. I'll dig back in with both suggestions and report back any findings. Enjoying the process.
    • also;  there several books on the internet on that subject.  good luck.  vin
    • Always hard so make a guess... Anyway, I think the problem is on the dial side, i.e. the dial train (cannon pinion, minute wheel, hour wheel, intermediate wheel). Could it be that the clutch wheel doesn't disengage properly from the intermediate wheel that drives the minute wheel when you set the time? If so the intermediate wheel may bind up the minute wheel making things slow down and then stop. Well, just guessing. Anyway, I'd check the dial train (motion works) and the keyless works. I think your idea of removing the cannon pinion to see if it solves the problem is a good idea. If it doesn't help you'll know for sure the problem is with the train of wheels or the escapement. Good luck and let us know of any progress or any new observations.

    • Hi  The difficult bit is removing the staff without bending the balance rim  hence the use of the Platax tool and the K&D tools to hold the balance flat. Some watch makers put the broken balance in a lathe and cut the rivit off, which is a skilled job so as not to mess up the balance hub.  I have in the past done it using a stake and a set of punches and was succesfull.  The K&D tools come up on the bay from time to time as do Platax tools who command a price greater than £250 the K&K s  go for arround the £50 mark.  I would reccomend that before embarking on this journey that you watch Mark our Hosts videos on UTube  and then decide on the course of action to take.     Hope all this is useful for you.   cheers
