I have a Tissot Visodate with an ETA 2836-2 (non-chronometer) automatic movement. The watch is several years old, never been serviced. It is running about 25 seconds fast per 24 hours. Is this performance in spec? Its not really concerning to me, I am just curious. It seems to be stable...not getting any worse over the past month or two, and it is pretty consistent day in and day out. I am wearing the watch during the day. It rests flat at night.
