Glashutte Original applying a blue dial on watches that are certainly their best-sellers: the PanoMatic Lunar and the PanoReserve. And  they also applied on some other classical watches,such as Glashütte Original Senator Perpetual Calendar. The blue dial is crafted in Glashutte Original’s own dial manufactory, in Pforzheim, Germany. Up to 40 separate operations are required to produce the refined and carefully finished faces of the timepieces. Just like the earlier this year with the PanoMatic Lunar and the PanoReserve, we have here an intense and vivid blue that plays a lot with the ambient light, changing from a deep midnight blue to a bright electric blue in full light.

This hue is obtained by a galvanic treatment, were the dial-makers must exercise precise control over the entire galvanic coloring process, ensuring that the tension is at the correct level, that the dial is submerged in the bath for precisely the right length of time, and that the correct distance is maintained between the elements in the bath, among other requirements. Matching with these blue dials are some alligator straps, also tinted in blue.Glashutte Original Senator Perpetual Calendar, that displays the calendar information in a quite specific and clean way. No sub-dials burdening the dial here but instead some legible and clear windows: hours, minutes and seconds are displayed on the central axis, the day is visible through a windows a 10, the months via another window that gives echo to it at 2, the leap year is simply indicated by a small aperture over the hands-axis, an oversized date at 4 and the moon-phases between 7 and 8. The dial of Glashutte Original Senator Perpetual Calendar is really clean and highly legible. This perpetual calendar module is powered by an automatic movement, Calibre 100-02, with reset function and 55 hours of power reserve. The stainless steel case measures 42mm.

Through the sapphire crystal case backs of the Glashutte Original Senator Perpetual Calendar, it is possible to admire the high finishing of the movements: screw balance with 18 weighted gold-coated screws, twin spring barrels, swan-neck fine adjustment, skeletonized rotor with 21-carat gold oscillating weight.
