Dual time complications are handy in the modern world, where we may be traveling, have loved ones in a different time zone, or need to work with colleagues across the country or even further afield. One way to track two time zones is with a GMT hand, but most of those are 24 hour hands, which requires a bit of mental arithmetic. Another way to do it is with dual dials, but those are tough to get aesthetically right. The Helgray Hornet takes a third way, with an internally rotating bezel that provides a second chapter ring.
