Hamilton unveiled its first regulator watch at Baselworld 2013: the Jazzmaster Regulator.
The new watch, part of the Hamilton Jazzmaster collection, uses Hamilton's new H-12 movement. The movement "acts as a facilitator of eye-catching design architecture" by allowing the off-centre positioning of the hour and second hands. It gives the watch a distinctive asymmetric design, and makes it easier for the wearer to read the minutes at a glance.
Three versions of the Jazzmaster Regulator are available, with blue or silver-coloured dials, and a choice of leather strap or stainless steel bracelet. The watch features dual-tone subdials, with the larger subdial indicating the hours, and a smaller subdial indicating the seconds. A central hand shows the minutes, with Arabic numerals displaying 5-minute intervals.
The watch has a stainless steel case measuring 40 mm, and a sapphire crystal with anti-reflective coating. The movement can be seen through a sapphire crystal exhibition case back.
