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.
I've grown somewhat accustomed to my 3x Bergeon loupe with headband. I remove my glasses to wear this. It works fine, and I'm comtemplating more magnification for certain tasks. Is there a quality product in the clip-on-the-eyeglasses variety? The clip on lenses that swing up and down look like they'd work well, but eBay gives mixed reviews, i.e. too heavy, low quality, poor light rendering.
If there were a high quality version of this device I think I'd like that. I'd be interested in the forum opinion of these optics. Should I just buy a Bergeon bakelite loupe in 10x and have done with it?
