Stopped working properly in 3 weeks

I loved this watch especially the mother of pearl dial and world time feature but it stopped working properly in about 3 weeks. I was wearing it every day and then all the sudden the time was about 15 minutes behind for no reason.

A pleasure in all the right doses

This is a classy timepiece with excellent consideration of spacing, a substantial gold bezel, and luminous, legible Arabic numerals. Neither natural nor synthetic light obfuscates the experience of reading the time, particularly with a face composed of iridescent mother-of-pearl. A pleasure in all the right doses.
