Watches

I usually just keep an eye on my auto watches compared to my cell phone (which is automatically coordinated to atomic time, so it’s just as accurate as time.gov). If I notice it’s more than a minute or two off, I adjust it.

If being accurate to the second is necessary for you, a radio-corrected or High Accuracy Quartz would be a good choice. Even the most accurate automatic watches will be off by a minute or two per month.
