Hi, my name is Ross. I am a rookie watch enthusiast and I am really puzzled here.
Could someone explain to me what kind of a problem am I facing with my timegrapher?
I do two sets of measurements with the same watch (1 day or 6 days apart) and receive vastly different results - to the point of being completely different from what I observe in real life.
For example, my timegrapher shows that my watch is running fast (or ahead of time), while in real life I observe that it runs 7 seconds per day behind. I even recorded a video about it so you could see it for yourself: https://youtu.be/mhGzf6aLMlY
How should I interpret that? Am I doing anything wrong?
I am working on a vtg. Citizen cal.7520 automatic movement.
I have put the watch on the timegrapher
The graph looks OK but the beat error shows 9.9ms. I presumed that beat error should be around 1.0~2.0 given the shape of the graph.
Is the beat error actually bad or the timegrapher is wrong??
Padd here from the UK.
It all started with a desire to fix a Submariner replica I bought off a lucky lucky man in Pisa, Italy while on a European tour.
Next thing I know I'm investigating Submariner replicas and building my own, signed by me, using a Seagull ST2130 movement, adventure watch.
Now I'm hooked, I took inspiration from Marks videos, now I'm happily starting to work on parts of the movement, and have recovered one or two movements where the stem came out, but wouldn't stay back in. I have built a few watches for friends and relations, but now I need to be able to service them when they come back to me.
I also have a couple of movements that run really badly, so I will be practising on those over the winter weekends. Full repair/servicing kit IS my Christmas present.
I really want to get one of those ST2130's, serviced and tweaked by me, doing a -------------------------- on my timegrapher. not a -.'-.'''--,'.'.' (and worse) that they do at the moment.
I wont start to list my watch collection, but it runs from a Casio digital to a Rolex pocket watch with Seikos, Citizens, Omegas and home builds in the mix.
Must do Mark's course, but I'm afraid I may have already learned 60+% of it already.

Pictures would help..most likely it is a snap on back which you pry off.most likely the rotor is loose or severely worn. Others may know better, but you probably could just remove the rotor and use the watch as manual wind only. Other possibilities include a donor watch to swap movement or get parts.
Hi, I guess I’m a watch collector. My wife thinks I may have a problem. Anyway I want to learn how to do some minor repairs and maintenance. I just happened on this form and am excited about it. I’ll go over the rules and be a great member. I live in Bessemer Alabama and work as a registered nurse.
the watch was serviced, not manually wound then purposely not worn overnight to check the wind down time, so if you ask me habits did change esp since he was sick and was not moving much. Now if he manually wound it and it did not run overnight then i would say without a doubt there is an issue with the service. I don’t think its wise to just automatically jump to service as the culprit, I like to give the professionals the benefit of the doubt. BTW Bauertime sorry for your loss - you will be in my prayers tonight
I hate these so called non scratch modern crystals. I usually scratch them the first few days of ownership. Then you need to almost burn out the dremel motor to polish it out with diamond paste. If they where good quality plastic, I could rub it on a piece of leather with some polish paste and be done with it in under five minutes.
