I bought a Tissot T-Race for 675 CADs, and after five days I regretfully discovered that my new watch is lagging behind. For every 24 hours, it lags by 72 seconds, that is almost a minute and a half per day. I have a collection of 16 other watches, half of which are much cheaper than this Tissot, and none of them had such a problem during the six years I had them.
