Hamilton H-20-S
The Hamilton H-20-S Hamilton is an exclusive skeleton movement, uniting proven craftsmanship with relentless accuracy. Contemporary decoration, ranging from brushed, skeletonized rotors to an intricate ‘H’-pattern on individual elements, add a sense of theater to traditional precision timekeeping. The H-20-S is making its debut in the Hamilton Jazzmaster Viewmatic Skeleton Lady and Gents watches in 2013, with the open dial design offering it a strong position center-stage for hours of fascination featuring skeletonized rotors and beautiful barrel drums and main bridges.

Hamilton H-12
This regulator movement opens up new doors for the Hamilton design team to create original ways of presenting the passage of time. The Hamilton H-12 acts as a facilitator of eye-catching design architecture. Behind the movement is the objective of modernizing a traditional horological complication, a true and proven symbol of accuracy, and turn it into a contemporary design object. The separation of the three hands creates new possibilities for design, in this case the off-center positioning of the hour and second hands for asymmetric appeal. Its first execution is inside the Hamilton Jazzmaster Regulator. The regulator complication first appeared in the late seventeenth century and was used by watchmakers for verifying the rates of their creations. Close to the heart of the brand celebrated as the “Watch of Railroad Accuracy” in the 1890s, the regulator was also relied on by railroad staff and made a huge contribution to safety.
