Most new mechanical watches will go through a short burn-in period. Nothing special needs to be done by the owner, the watch should take care of itself...
Before a watch makes it to your wrist, it has likely been sitting in the jewelers store or a warehouse. Oils and lubricants can pool in certain areas. It takes 1 or 2 months for the oils to be distributed to their proper locations. The moving of the parts will also wear away and microscopic imperfections that most parts have. After a couple of months the watch will be properly broken in and run with more precision.
This tip is completely wrong. There is no "break-in" period. Oils in watches are used in tiny amounts and held in place by capillary action. They do not pool nor do they require distribution. There should be no wear-in of parts, they are, in fact, precision-made. Note that, if this were true, all of the lubrication in a new watch would be contaminated with metal debris and require immediate replacement. Note also that, if any of this "tip" were true, there could be no chronometer-certification of watches since there rates would be constantly changing during usage. This tip is pure bunk and apparently comes from an incorrect analogy with the old "break-in" period for new cars (not even true for cars anymore). Please remove this erroneous and hard-to-squelch information.
