Classic design, contemporary style The striking combination of stainless steel and a dark dial gives the BENU Power Reserve a clean, elegant look. In the second version, the stainless steel case takes on an anthracite hue. This is achieved with a coating technique known as DLC. The abbreviation ‘DLC’ stands for ‘diamond-like carbon’. In this technologically advanced process, an ultra-thin, carbon-based layer is vapour-deposited onto the stainless steel in a vacuum. What makes this layer special is its molecular structure, which combines the properties of graphite and diamond. This not only gives the case a sophisticated, dark appearance, but also makes it exceptionally scratch-resistant, robust and durable. Here, Moritz Grossmann brings traditional craftsmanship together with state-of-the-art surface technology. Experience the mechanism: the power-reserve indicator At the mechanical heart of the BENU Power Reserve sits the very complication the watch is named after: the indicator showing how much energy the movement still has in reserve – information of real consequence to anyone wearing a mechanical timepiece. With a hand-wound calibre in particular, the wearer has to step in before it runs down and rewind the movement via the crown. That is what the power-reserve indicator tells you, and it is a charming detail in its own right: it brings the mechanism to life and serves as a constant reminder that what sits on your wrist is a piece of fine craftsmanship. At Moritz Grossmann, the power-reserve indicator is perfectly attuned to the manufactory’s understated, classic design: It is displayed linearly in a small aperture in the dial below the ‘12’, where a bar appears that is controlled by a differential gear. When the movement is fully wound, a completely white bar is visible; as the power reserve decreases, the bar gradually turns black. In keeping with the design of the new BENU Power Reserve, the power-reserve indicator too is held strictly to black and white. The dial: interplay of light and texture The dark anthracite shade lends the dial a fascinating depth, which is further emphasised by the high-contrast finishes. The outer ring, which features the applied numerals and hour markers, stands out from the centre thanks to a delicate circular pattern known as ‘azurage’. The centre has been given a subtle matt finish. Sweeping above it are steel hands, shaped by hand in the manufactory. Their gently rounded, domed form and wafer-thin tips are quietly captivating. The movement: a calibre 100.2 Working beneath the dial of the BENU Power Reserve is calibre 100.2. It is based on the 100.1 movement, with an additional differential gear added to drive the power-reserve display. The movement uses the Grossmann manual winder with pusher, a cantilevered balance cock with Grossmann micrometer screw, a separately removable clutch winder and the mass-optimised Grossmann balance. The sapphire crystal caseback reveals the intricately finished components of the movement – the finest German craftsmanship from the Moritz Grossmann manufactory. The special '1826' engraving on the balance cock marks the year the manufactory’s namesake was born.
