Beat Error on 3235 Clone Movement

[derjenigewelcher]

Hello folks

I have a question, I have a QC part (already green, ask anyway) present a RF Starbucks. The work is an R3235 clone, so this new Hybrid 3235. I was a little puzzled by the beat error.
The TD says it's ok in the QC. you just read various things on the bloody internet. Can someone inform me whether these 0.5ms have to go straight to the watchmaker?

Of course, 0.0ms is better, but in principle, according to my research, the gang deviations themselves do not harm the work, right?

would be happy to receive any input or experience from you!


greets Sam

Beat error is just how long the balance takes to swing from 1 side to the other. You can easily open the case to regulate it yourself.

0.5 is usually considered the maximum allowable amount of beat error. So technically you’re within spec but watchmakers normally adjust for 0.0 or 0.1. It’s a measurement of the symmetry of the balance wheel’s swing in each direction. You can adjust yourself if you have a timegrapher but i don’t think service is urgent unless you want some peace of mind knowing your movement is running at its best.

It won't harm the movement bro. Also, if you've never regulated a movement I wouldn't start with this one. Practice on a cheap rep movement first to get a feel for how the adjustment arms work.

Adjusting beat error is more challenging than adjusting s/d, and the adjustment arms on this next-gen 3235 hybrid are on the opposite side of the balance assembly and inconvenient to access.

The fake free sprung balance arm on the front side of the RF balance is a decoration and does nothing.

Thanks for your inputs, appreciate it! Ok then I will let it be as it is
I also looked on "witschi" homepage, there you see that 0-0.5ms is in range of a good movement.
