The dream of manufacturing mechanical watches to the highest standards of craftsmanship in the spirit of the visionary and watchmaking genius Moritz Grossmann came true again in 2010.

To mark the occasion, the manufactory’s designers devised a new logo – two straight lines at the bottom and a semicircle segment at the top framing the Moritz Grossmann i/Sa lettering. These lines precisely indicate the shape of the lower edge of the characteristic Grossmann two-thirds plate, typically used by Moritz Grossmann in his pocket watches and which, thanks to recesses in the movement, allow a view of the balance.

To commemorate the revival of the brand and pay tribute to the inventor, visionary and master craftsman Moritz Grossmann, a traditional version of this wristwatch is now being released. The Power Reserve Vintage features a historic dial in argenté echoing Moritz Grossmann’s classic pocket watches. Finely crafted Roman numerals in black and the original logo featuring the ‘M. Grossmann’ typography from 1875 grace the dial paying tribute to the master, as he was respectfully called in Glashütte.

The hands of the new model also take their inspiration from the 19th-century examples of Moritz Grossmann’s pocket watches. The pear-shaped tip of the hour hand forms a beautiful contrast to the wafer-thin, needle-like shape of the minute hand, measuring a mere 0.1mm at its narrowest point. Only the second hand with a twentieth of a millimeter diameter at its peak surpasses the filigree appearance. As with all Grossmann hands, these display instruments are also handcrafted in the manufactory and manually annealed over an open flame. Kept in blue, the hands harmonize with the blue/white power reserve indicator.

The caliber 100.2 of the Power Reserve Vintage uses Grossmann’s manual winding with a pusher, a cantilevered balance cock with Grossmann micrometer screw, a separately removable winding module and the mass optimized Grossmann balance. The caliber 100.2 is an extension of the caliber 100.1. It includes an additional gearbox to indicate the power reserve. This differential gear is located below the ratchet wheel – as in the historic Glashütte observation watches. The stopwork was moved upwards between the crown wheel and the ratchet wheel.

A segment mounted in the center of the caliber drives the output of the gearbox, creating a two-colored bar display below the logo to indicate the remaining power reserve. This shows the watch’s remaining running time. When the mainspring is fully wound, the bar is completely white and turns increasingly blue as the power reserve decreases. The bar complements the dial with its slim, filigree style. A sapphire crystal back on the reverse of the watch reveals the intricately finished parts in the Power Reserve Vintage, showcasing the finest German craftsmanship from the Moritz Grossmann manufactory.
