Hamilton Jazzmaster Regulator Auto features an interesting regulator complication that first appeared in the late 17th century and was used by watch manufacturers as a confirmation for the quality of their creations.
The new Hamilton Jazzmaster Regulator family comprises three different timepieces. They feature an asymmetric design of their dials that in an amazing way detaches the minutes from the hours.

The beating heart of the new Hamilton is the exclusive H-12 movement which can be seen through a transparent case back of the watch.
What is interesting about these watches is that they perfectly combine tradition and modernity. The separation of the minute and hour hands on to different axials and subsdiary dials has the added improvement of facilitating minute reading at a glance. Contrast is the main characteristic of the watch. The counters on its silver dial have a sun brushed finish, while the framing surface has an opaline one.
