I'm in NYC. email me at nycddancer at gmail if you want to send your watch to a total stranger on the internet until they get around to doing a testing run and then hope they send it back to you.

There are three main ways to measure accuracy

> On the wrist
Watches are being worn on the wrist when they are doing their job. When wearing your watch, you simply note how the time it's showing compares to atomic time (say, from http://time.is), and then a few days later, how far it's drifted. This gives the best idea of how the watch actually performs in daily use. However, it is not necessarily repeatable - if your wear pattern (hours worn per day, activity while worn) varies, so will the rate. It also takes a long time to get an accurate idea of the accuracy. There are also apps to help with this - I use WatchCheck for Android. This method also is generally not good at measuring isochronism of automatic watches, since they will generally stay wound all day.
