Moritz Grossmann, reconstituted in 2008 under the stewardship of Christine Hutter in the original Glashütte atelier of its nineteenth-century predecessor, represents a deliberate resurrection of Saxon finishing doctrine applied to contemporary architecture. The Benu Power Reserve in stainless steel, reference MG-004123, is an iteration within a family defined by the hand-finished Grossmann balance wheel and the proprietary three-quarter plate construction visible through the exhibition caseback — a lineage that prioritizes the movement as the primary aesthetic argument. Concordantly, the dial of this reference merits analytical attention: the sector-style power reserve subdial and the graduated finishing achieve a restrained legibility that positions this piece firmly within the upper stratum of its category. The caliber 100.2, manually wound across a 42-hour reserve, is where Grossmann's case is most persuasive — the Nabla-shaped regulator, in-house lever, and hand-beveled bridges represent finishing decisions that compress favorably against far more celebrated Genevan predecessors. The 41-millimeter stainless steel case, at 11.65 millimeters thickness, presents a proportion somewhat in tension with the dress classification; as you undoubtedly gather, the category demands a discipline the case only partially delivers. The kudu leather strap is adequate without distinction. The value axis is where the probability of friction with the prospective acquirer is highest: at $42,840, the reference occupies contested territory against established manufacture alternatives with superior secondary market liquidity. Ergo, the investment is one of conviction rather than calculation.
