I recently decided to get a Tissot Veloci-T Automatic watch, as it's the most affordable, good looking (to my taste), Swiss, automatic chronograph I could find. And does it look gorgeous in the metal... wow, it looks like it could cost way more.
To cut a long story short, after receiving a faulty Veloci-T I ended up getting two working ones.
However, while they both seem to be reasonably accurate as watches, the chronograph part of them is too fast. Compared to internet time and a quartz watch, one of the Veoci-T is too fast by just over a second per hour. The other one is much better, still faster than my references, but drifting ahead by around a second in 5 hours (all this is as seen on the big central seconds hand).
But the strange thing is that the minute hand and the small seconds hand (pertinent to the watch, not the chronograph section), are nigh on perfect on both watches.
So to me, being basically a beginner and somewhat ignorant about watches, this looks odd and raises a couple of questions:
- Is it normally possible for a watch to be very accurate, and yet for the chronograph function on that very same watch to be significantly too fast? (That would imply largely independent mechanisms, does that make sense from a watchmaking point of view?)
- Could it be that the chronograph movement has been magnetized, while the main watch movement hasn't?
- Logically, shouldn't the chronograph section be more accurate than the watch section? I mean, the chronograph is supposed to be a chronometer substitute for precise measurements, whereas the watch is for looser, at a glance timechecking.
I realise that it's a C01.211 movement and it's not going to rival the proper automatic movements that some of you guys have on luxury watches. And the Veloci-T is not a COSC certified chronometer. But still, the fastest of my two Veloci-T has a chronograph that's outside Tissot's normal tolerance for a mechanical watch. This is somewhat odd i think... isn't it?
And the Tissot website does not mention tolerances for the chronographs, just for mechanical watches in general.
NB: Both watches were manually wound to get them started, and rested on a flat surface most of the time, on their side, crown up. When I picked them up I held both at the same time for comparison purposes, so they were treated consistently.
