Howdy all,
I had a question about timegrapher readings and I would love if I could get an explanation of what I am looking at. Before I get roasted I want to make clear I've made an effort to figure it out myself by reading this and page 14 of this but I am still in need of advice.
Basically the timegrapher rate reading on a watch I ordered starts at +2s, then increases to +5s, then to +7s in the span of 13 seconds in a QC video I was provided. The timegrapher line has an upwards curve. I am wondering if this upwards curve is indicative of a defect with the movement meaning it needs immediate work done for it to function properly. Is this a serious issue that I should RL? Should I ask for a longer reading?
To clarify, I am NOT trying to be picky and get a rep that's within COSC standards. That doesn't concern me at all. What I am worried about is the variance in rate readings and the fact that the timegrapher chart line has a curve to it, rather than being a straight line. In the Witschi guide, the graphs that show movements that are in fine condition but just moving slow/fast all show the timegrapher lines as straight, whereas curved lines seem to indicate damage. Mine isn't as wavy as some of the examples provided by Witschi, but it has a curve nonetheless. I'm concerned that if the curve follows this trajectory, the watch will have major problems keeping time. Can someone a little more well versed on the topic explain what is going on here?
