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.
Here's a brand new one for starters which looks to be the same as yours (?) ... https://www.ebay.co.uk/itm/DIAL-TAG-HEUER-F1-HX0266/302649416687?hash=item46774f9bef:g:m1UAAOSwYNxagv4f . Someone else on this forum might have another source other than ebay.
However at this price it's also worth looking out for (non-working) complete watches in good condition. Assuming this is the same as yours then this sold for £41 recently as an example of what can come up if you keep an eye out: https://www.ebay.co.uk/itm/Ladies-TAG-HEUER-F1-200m-Watch-Spares-Or-Repairs-/293105389179
Perhaps one further suggestion is also to consider an alternative Heuer dial. Unless you're set on the pink there seem to be quite a lot of other Heuer dials available. Of course you'd have to double check diameter and dial feet positions but just an idea if all else fails!
Hi Rexxus The parts you refer to are the center wheel and the canon pinion, One has to remove the canon pinion the remove the center wheel., To do this you will need a removal tool (available on EBAY) to remove the pinion and the center wheel will drop out. I have attached the TZ glossary so as you can identify the various parts by name. The same tool also is billed as a watch hand remover and provides a parallel upward pull so as not to bend the pinion or indeed watch hands, happy days
