The chronograph hand on my Speedmaster Professional doesn sit exactly on the twelve; is my watch defective?
This is not uncommon, and it is not a major problem to worry about. Typically this occurs when a watch hasn’t been serviced in a while and the remedy is to have it attended to when you choose to have the watch serviced (Cleaned, Lubricated, Adjusted, often called CLA). If your watch doesn’t reset to “zero” geting this item adjusted but not getting the watch cleaned and lubricated at the same time won’t necessarily prevent the misadjustment from reoccuring. If you can live with the watch being off by a couple fifth’s of a second, it won’t harm the watch to continue to use it until it’s a convenient time for you to be without it while it’s being serviced. When you take the watch in for servicing, explain all of the issues you note with the watch, so that the watchmaker can attend to each of the items noted.
