The Senator Chronograph Panorama Date displays the signature symmetrical harmony of the manufactory’s classic yet contemporary Senator line. The dial presents an elegant 12-hour chronograph counter at 12 o’clock, while the Panorama Date display with white numerals on a deep black ground is positioned at the centre of the lower half of the dial. The small seconds dial with black and white power reserve indicator appears at 9 o’clock, the 30-minute chronograph counter at 3 o’clock. The main hands are filled with blue shining SuperLuminova. The new steel case now is waterproof up to 100 meters.
Let us have a closer look at the technical features of this quite unique Calibre:
The manufactory’s in-house design team has successfully integrated a unique combination of features: central stop seconds hand, 30-minute and 12-hour counters with fly-back mechanism; small seconds counter with power reserve indicator (70 hours), and Glashütte Original’s compelling implementation of the Panorama Date display.
In contrast to more complex constructions, the automatic 4 Hz-column-wheel-Calibre 37-01 has been designed to be as simple and compact as possible. With a diameter of 31.6 mm and an essential simplicity, the movement has an increased stability and is less susceptible to interference, resulting in superior performance over time.
The new chronograph presents a greatly simplified column wheel mechanism with fewer individual parts. The movement features a bi-directional rotor; a single spring barrel manages the 70-hour power reserve. Regulation is performed using four gold screws on the balance rim; the absence of a regulator on the spring allows the movement to run continuously over a much longer period of time, resulting in increased precision.
The chronograph start and stop functions are activated by the pusher at the upper right side of the case, the fly-back mechanism by the pusher at the lower right. Pressing the fly-back pusher halts the on-going chronographic time measurement and the chronograph hour, minute and second hands jump back to zero. The time measurement does not stop, however, but rather begins immediately a new measurement as soon as the fly-back pusher is released.
The manufactory chronograph from Glashütte Original presents characteristic features and surface finishings for which the Saxon watchmaker is famous.
A domed sapphire crystal, antireflective on both sides, protects the dial side, while a second sapphire crystal set in the case back opens up the automatic movement for closer inspection.
Among the exquisite features on view is the rotor and the chronograph bridges mounted on the Glashütte three-quarter plate; Glashütte stripe finish on the automatic bridge, blued screws, and the central skeletonized 21-carat gold rotor with double-G logo. Also of interest is the new oscillation system regulated by four gold screws, visible through the case back’s sapphire crystal.
