Moritz Grossmann gives the Benu Power Reserve a darker Glashütte edge

Moritz Grossmann has a particular way of making restraint feel deliberate rather than plain.

Its latest Benu Power Reserve editions lean into that character with a darker, more contemporary treatment of one of the Glashütte manufacture’s defining watches.

Created to mark the bicentennial of the founder’s birth, the pair brings together brushed steel cases, anthracite sector dials and the brand’s quietly distinctive linear power reserve display.

At a glance

A darker Benu with sharper sector-dial architecture

The Benu carries unusual weight within Moritz Grossmann’s modern history, as it was the watch that marked the brand’s revival in 2010.

The Power Reserve followed in 2013, adding a more functional layer to the clean three-hand layout without disturbing the watch’s formal Glashütte character.

For these new editions, Moritz Grossmann keeps the familiar 41mm three-part case and gives it a more modern attitude through brushed matte stainless steel or dark grey DLC-coated stainless steel.

The proportions remain elegant at 11.65mm thick, with tapering lugs and a slim bezel that leaves the dial to do most of the visual work.

That dial is where the watch feels most changed.

Instead of a traditional dress-watch surface, the anthracite sector layout is built from contrasting textures and levels, with a smooth outer minute track, a snailed chapter ring and a grained central field.

Applied Arabic numerals appear at 12, 2, 4, 8 and 10 o’clock, paired with indices to keep the geometry crisp without making the composition busy.

The linear reserve remains the quiet signature

Power reserve displays often announce themselves with a sweeping arc, but the Benu Power Reserve has always taken a more discreet route.

Here, the 42-hour reserve is shown through an elongated trapezoid aperture positioned between noon and the central axis of the hands.

The display uses dark grey and white bars to suit the new dial treatment.

When the movement is fully wound, the white bar is visible, then gradually gives way to dark grey as the available running time drops.

A recessed small seconds sub-dial at 6 o’clock adds balance to the upper display, while its smooth finish sets it apart from the grained centre.

The hands are another detail worth slowing down for.

They are manually crafted in tempered steel, slightly wider and more domed than those found on other Benu Power Reserve models, with polished bevels, wafer-thin tips and a closed rhomboid counterweight on the minute hand.

Calibre 100.2 keeps the Glashütte craft in view

Inside is the in-house calibre 100.2, a manual-winding pillar movement derived from the calibre 100.1 and fitted with an additional differential gear for the power reserve display.

It runs at a slow 18,000 vibrations per hour and stores 42 hours of power when fully wound.

The movement is visible through the sapphire caseback, where Moritz Grossmann’s traditional hand finishing is part of the appeal.

The two-thirds plate carries Glashütte ribbing, while the balance cock is hand-engraved and holds the Grossmann balance wheel.

The watch also uses the brand’s patented winder-and-pusher system, pairing the crown with a pusher at 4 o’clock.

The system is designed to reduce the chance of dust entering the case when the crown is pulled, while also allowing the movement to be restarted through the pusher.

Details & Specifications

These Benu Power Reserve editions won’t be the loudest watches in the room, and that’s largely the point.

They suit collectors who appreciate Glashütte watchmaking when it’s precise, quietly technical and finished with the kind of human detail that rewards close inspection.
