Moritz Grossmann - BENU Collection Edition



















Moritz Grossmann - BENU Collection Limited Edition NEW

Glashütte based Moritz Grossmann watch brand is presenting its new model Benu, an extraordinary timepiece featuring a distinctive personality and discreet elegance. It has a delicate rose-gold bezel frames the solid-silver dial with its crisp Arabic numerals and the fine-tipped brown-violet hands. They have the same hue as the annealed screws that are visible on the surface of the calibre. The upper half of the dial beneath the “12” displays the traditional “MORITZ GROSSMANN GLASHÜTTE i/SA” signature. The small arc above the maker’s name and the horizontal lines on either side of the provenance symbolise the brand-typical cutout of the plate above the movement that exposes the screw balance, its beating heart, when viewed through the sapphire-crystal back.

Following an old tradition, the subsidiary seconds dial stands above the “6” and is slightly recessed to allow the hour and minute hands to hover as closely as possible over the dial. The precision scale graduations and the slender hands are reminders that a watch is meant to accurately keep the time. The aesthetic clarity of its face is reminiscent of a Glashütte precision instrument from the 19th century. Shaped in the form of stretched rhombuses, the steel hands consist of two parts (hand and bushing), which are manually crafted, hardened and ground by Grossmann’s watchmakers. This sequence of time-consuming processes is the only way to impart three-dimensionality to the hands and achieve the daintiness of the tips. The shape of the hands and their remarkable length assure precise readings of time. Brown-violet was chosen as the annealing colour – it is the darkest hue of steel obtainable with thermal hardening.

As a prominent contrast, the eyes of the hands are mirror-polished. The antireflective sapphire-crystal back reveals the inner life of the watch with seductive depth. The curved, milled cutout of the German silver 2/3 plate, a typical Grossmann hallmark, puts the spotlight on the large screw balance and its breathing hairspring. The plate itself bears the hand-engraved brand signature: “MORITZ GROSSMANN GLASHÜTTE i/SA”. The three screwed gold chatons that secure the jewel bearings are eyecatching plate accents just like the white sapphire bearing jewels and the brown-violet screws that were naturally annealed over an open fire. Three-band snailing on the ratchet wheel complements the sublime harmony of the movement. The watch is unique in its orchestration.

The construction of the calibre 100.0 movement is a functional work of art and a feast for the eyes of every connoisseur. The German silver 2/3 plate replaces a number of bridges and improves the mechanical stability of the movement. Polishes, graining, snailing, and wide Glashütte ribbing embellish the parts, and the inscriptions are always engraved by hand as well. German silver, steel, the brown-violet tint of the screws, as well as the gold of the chatons and of the large balance wheel rim constitute a classically discreet composition of natural material colours. A loupe allows the observer to delight in the superb finissage of the surfaces and the bevelled, mirrorpolished edges on a visual excursion across the individual levels of the movement.

A classic lever escapement establishes the link between the going train and the oscillation system of the calibre. Found in almost all mechanical watches, this escapement was modified according to considerations proposed by Hugo Müller (1863 to 1943), a well-known Glashütte regleur. The classic screw balance breathes with a Nivarox hairspring featuring a terminal curve that was first calculated by regleur and chronometer maker Gustav Gerstenberger (1886 to 1983) in Glashütte. It performs 18,000 semi-oscillations per hour, which is equivalent to a frequency of 2.5 hertz.

The Benu incorporates a number of innovations and traditional features that reflect the heritage of Moritz Grossmann:
• The oscillation system and the escapement are mounted on two hand-engraved cocks:
The large one, for the balance wheel and the hairspring, is cantilevered according to Moritz Grossmann’s design for his lever chronometers. It also carries the Grossmann micrometer screw. The escape wheel sits on the smaller, adjacent cock. At a lower level, a third, snailed cock holds the lever. Its size was deliberately reduced to showcase the escapement.

• The Benu features an index adjuster that allows the watch to be regulated to onesecond accuracy without disrupting the equilibrium of the oscillation system. The Grossmann micrometer screw enables accurate, tension-free adjustments of the index tail in both directions.

• On the inside, the balance spring is overcoiled with a quarter arc and pinned to the classic roller.

• When the crown is pulled, the seconds hand is stopped to allow precise timesetting. The stop-seconds device relies on a spring that advances a pin onto the circumference of the double roller and temporarily halts the oscillation system.

• A modified Glashütte stopwork secures the tension of the mainspring. After winding, it allows the ratchet wheel to reverse somewhat and slightly relax the mainspring. Grossmann’s watchmakers implement this controlled backlash with a slotted hole in which the pin on the stop click can slide.

• Two beautifully contoured pillars – evocative of Grossmann’s pocket watches of old – and the separately removable winder – a refinement of the Glashütte clutch winding mechanism – support the plates.

• The winding wheels have polished bevel faces in the toothing and sparkle with exceptional brilliance. The largest one, the ratchet wheel, is also decorated with traditional three-band snailing, accentuating a harmonious match with the wide ribbing and the freehand engravings on the cocks and the 2/3 plate.

• As in old Grossmann pocket watches, the jewels – white sapphire – are set in prominent gold chatons. Together with their brown-violet annealed steel screws, they stand out over the surface of the plate.







































The name of Grossmann’s first revival watch is Benu. It comes from ancient Egyptian mythology: Bennu (as spelled in English), the divine heron, settled into its nest one evening and was consumed by fire there. It left an egg from which another Bennu bird hatched the next morning.

Moritz Grossmann was an ingenious watchmaker who lived from 1826 to 1885. In the Saxon town of Glashütte, he crafted numerous pocket watches, various chronometers, and a few precision pendulum clocks that are still coveted collectors’ items at international auctions. Now, 125 years after the death of this eminent German master of superior watchmaking, watches that bear his name are once again available. The Benu radiates understated beauty; its gestalt flatters the eye and the wrist. It gives Moritz Grossmann’s horological accomplishments a new life in the 21st century: graceful in design, innovative and premeditated in its mechanical finesse, and immaculate in its traditional artisanship. The Benu is much more than the sum of its 188 parts. Every single element is crafted with the same precision and perfection. As always, details are what manifest the utmost in quality.

This also applies to the carefully hand-stitched brown alligator strap secured with a butterfly clasp that makes it easy to put on and take off the watch. It, too, is crafted from 750 rose gold, and features a dependable pushbutton catch. The Benu, Ref. 100.1010, is limited to 100 watches worldwide and is available from 2011.
The price in Germany is 16.800 Euro

Hublot - Masterpiece “MP-02 Key of Time”


Hublot's MASTERPIECE collection is dedicated to complication watches and extraordinary movements, which are the fruit of cutting-edge research in the field of mechanics and engineering. The appearance of this new collection was made possible by Hublot reinforcing its manufacture's workforce in 2010 with a team of 30 staff of the highest level, entirely dedicated to Grand Complications. The first piece in this collection, the MP-01, was presented in January 2011. It was a barrel-shaped titanium watch with a shaped chronograph movement offering a 10-day power reserve thanks to its three barrels working in series, and produced in a series of just 100 pieces. Now Hublot introduces the second member of the MASTERPIECE collection: the MP-02 Key of Time.

The MASTERPIECE MP-02 is an innovative timepiece that gives you the ability to manage the passing of time as you wish. The mechanism driving the MP-02 Key of Time, thanks to a three-position crown, enables you to “modulate” the speed at which the hours and minutes pass, according to your wishes.

Position 1: If you want to savour every second of the passing of time: you can slow down the speed of the watch hands, dividing time by 4, whereby 1 conventional hour is represented as quarter of an hour on the MP-02 Key of Time display.

Position 2: If you want “real” time: select normal hand speed, to retain “standard” time, whereby one conventional hour equates to one hour on the MP-02 Key of Time.

Position 3: If you want time to pass quicker: you can accelerate the hand speed, multiplying time by four, whereby a conventional quarter of an hour is represented as one hour on the MP-02 Key of Time Key of Time display.

Hence with Key of Time, the wearer can make happy moments last four times longer or make difficult moments four times shorter, while retaining the option to “return” to real time at any moment. Three different indicators in a star arrangement on the dial each indicate the current speed of time, to avoid any confusion. You can leave this complex mechanism in position 1 or 3 indefinitely, and then, simply by returning it to position 2, watch the hands readjust to conventional time display. This performance is made possible by a genuine “mechanical memory” built into the movement. In addition to this exceptional complication, the MP-02 Key of Time boasts a vertical flying tourbillon cage, with the particularity of a seconds indicator on its edge.
