Owner’s guides

Your first 30 days with a new watch

The box tells you what the watch measures. These 40 guides — one per watch we rank — tell you which of those numbers to believe in the first week, which need a month, and what to set before the first run so the month is not wasted. Still deciding? Find the watch first.
