Moritz Grossmann BENU Power Reserve Vintage Rose Gold
Reference: MG-002269
Unmistakably BENU, vintage timepiece in honour of Moritz Grossmann
Presenting the first model of the newly founded independent Glashütte watch manufactory Moritz Grossmann in 2010, Christine Hutter saw a 125-year-old dream come true. The dream of manufacturing mechanical watches to the highest standards of craftsmanship in the spirit of the visionary and watchmaking genius Moritz Grossmann in Glashütte again.
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.
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.
The calibre 100.2 of the POWER RESERVE Vintage uses Grossmann’s manual winding with a pusher, a cantilevered balance cock with Grossmann micrometre screw, a separately removable winding module and the mass optimised Grossmann balance. The calibre 100.2 is an extension of the calibre 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 centre of the calibre drives the output of the gearbox, creating a two-coloured 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.
