Officially launched in 2014, Glashütte Original's newly developed Calibre 37 is an integrated chronograph movement that features innovative, compact and highly functional design, and offers exquisite precision and reliable performance. As an inaugural collection, the manufactured released two variants of the Senator Chronograph Panorama Date in platinum and red gold. Now, a sportier version in stainless steel joins this collection.
The 4Hz automatic manufactory movement assures maximum functionality through its efficient and compact method of construction. An example is the switch lever; in the Calibre 37 series chronographs, in contrast to previous designs, the lever is comprised of only one part. The movement thus guarantees the highest possible switching security, with error potential and susceptibility to interference effectively reduced to near zero. The chronograph’s reliability is also enhanced by the space-saving coupling clutch, which operates by means of an oscillating pinion. It was designed to travel the same short path when both engaging and disengaging the clutch.
Sophisticated technical solutions assure the new chronograph’s particularly high degree of precision. Adjustment is handled without a regulator, using four gold screws on the balance wheel to enable a continuous, and thus more precise, performance of the watch over an especially long period of time. Numerous other components and functions contribute to assure the precision of the manufactory Calibre 37-01.
The new version of the Senator Chronograph Panorama Date is available alongside the other two versions in platinum and red Gold at Glashütte Original Boutiques and selected retailers worldwide.
