15 seconds a month is 3 minutes per year, and I don't want to bother having to fix my watch every few month.

Simply to catch a train it's important to have a precise watch.

In my country, 3 minutes is not enough difference to miss a train (it's probably been cancelled already ;)), if you live in Japan, I can understand. Comparing your watch to another timepiece is a fairly common occurence imo.
