Thank you everyone for answers so far. The most economic solution is of course a wristwatch. If it is worn all the time, it will have a more constant temperature and be more accurate. I would love to see a graph of error vs temperature. There is a bit of the luck of the draw with them. I had one Timex that would loose less than a second every three months, but it now beeps with the fishes. My present one is less accurate. The manufacturers obviously have some standards, but they vary quite wildly. Geoffrey Kolbe also warned us that there is a burn-in period of a few months. He used a small quartz alarm clock as well as a wrist watch , but I can't recall how it was for accuracy. I love fine mechanical devices and would not turn down a mechanical chronometer if given to me, but they are getting a bit pricey for my budget. If I had that kind of cash, I'd get a Bretling.
