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??
ST96 movements Oris used were signed on one of the bridges, crowns were signed as well as the case backs, however, dials are the rare and valuable hallmarks. Even if all parts were original, a non genuine dial, knocks the value of the piece down to that of used parts.
ST96 movements currently made in India are at worst of slightly inferior quality to vintage Asian made one's put in Oris. Only Oris calibers were swiss made.
this is nice forum I found yesterday. This particular topic is really interesting, thanks to everyone who shared their experience.
I see that there was no updates here for a couple of years. I'll put here some YouTube videos I found interesting. Maybe it will be also helpful for somebody.
