The Moritz Grossmann Benu | family history
The Benu is the most attainable Moritz Grossmann. It carries the hand-finish DNA of the Atum (hand-engraved balance cock, three-quarter plate movement architecture) in a slightly simplified execution. For buyers entering the German independent watchmaking conversation, the Benu Pure is the correct starting point.
Grossmann's contemporary dress collection: cleaner silhouette than the Atum, still showcasing the house's in-house caliber and distinctive German finishing.
2008-2015 · Grossmann's revival and the Atum
The Moritz Grossmann manufacture was revived in 2008 in Glashutte, drawing on the workshop traditions of the original Moritz Grossmann (1826-1885). The brand's flagship, the Atum, carries a hand-wound movement with a hand-engraved balance cock, a three-quarter plate, and beveled steel components finished by hand to a standard that places it in direct comparison with A. Lange and Sohne. The Atum established the Grossmann standard; the Benu followed as the more accessible interpretation.

2016-present · The Benu as gateway reference
The Benu Pure carries the same hand-engraving and three-quarter plate architecture as the Atum but in a simpler overall movement execution and a thinner case. The result is a watch that genuinely represents Grossmann's craft philosophy at a lower entry price. Production quantities are small; the brand produces a few hundred watches per year total across all references. The Benu is the most-produced Grossmann reference by that standard.
How to read this family
Two questions for Benu buyers:
- How does Grossmann finishing compare to A. Lange and Sohne? Lange is the more established name in Glashutte fine watchmaking and carries a corresponding premium. Grossmann is a genuine peer in terms of movement finishing quality; the hand-engraved balance cock on the Benu and Atum is executed at a level that holds comparison with Lange's equivalent. Grossmann trades at a lower price, which represents genuine value for buyers who evaluate finishing directly.
- Is the Benu the right Grossmann to start with? Yes, unless your budget reaches Atum territory. The Benu Pure communicates the brand's movement architecture, finishing philosophy, and dial sensibility. It is produced in sufficient quantity to be findable. And it is the watch that Grossmann collectors most often point to when they are explaining the brand to someone encountering it for the first time.

- 1Open
Benu Pure: open-worked dial showing the three-quarter plate movement, Grossmann caliber 100, hand-finished Glashütte manufacture.
- The case for it:
- The Benu Pure is what German watchmaking looks like when freed from the volume constraints of Nomos or Lange. The three-quarter plate architecture is visually beautiful, the hand-chamfering is done correctly, and the Grossmann double-click winding prevents crown damage. This is the correct buy for anyone who loves German horology and finds Lange too expensive and Nomos too simple.
- Consider instead if:
- Lange dominates the Glashütte market for collector attention and secondary market strength. The Grossmann is the better value at current prices but requires more patience to sell.
