Moritz Grossmann BENU 10th Anniversary Collection – Platinum and White Gold Models with Dark Enamel Dials and Model ‘Lost in Space’

Celebrating 10th anniversary of revival of the great watch making legacy, the German luxury watch manufacture Moritz Grossmann launches limited editions of their original BENU, the new manufacture’s very first watch. There are three new limited edition BENUs :  the BENU ‘Anniversary’ – two luxurious enamel pieces with a limitation of ten pieces in platinum and a further ten in white gold; and the BENU ‘Lost in Space’ – an imaginative, eccentric hybrid piece, limited to 26 pieces.

Platinum and White Gold Models with Dark Enamel Dials
Both of these anniversary specials have unusual dark-coloured, grand-feu enamel dials. Platinum model features a deep blue dial and the white gold version has a powerful black dial.  The rare surface gloss will make any watch enthusiast’s heart skip a beat, whilst the clean white numerals and polished stainless steel hands make each watch clean to read.

Both models have a display back that showcases the calibre 100.1 with its usual High-Artistic finish – but with an eye-catching twist. The hand-engraved balance cock is crafted in yellow gold instead of the usual German silver, providing a special complement to the raised gold chatons.

BENU ‘Lost in Space’
The third anniversary watch is an adventure in proportions. It is a hybrid of the small calibre 102.0 with a diameter of merely 26.0 mm and the case from the rose gold BENU Tourbillon, diameter 44.5 mm.

The movement sits behind a hand-crafted dial which resembles a moon, floating off-centre within the case.It is rendered in hand-cut relief engraving with an intriguing 3-D curved surface. Two sub-dials in contrasting grand-feu enamels sit on the moon’s surface.  The hour and minute display is placed centrally in radiant white enamel. A small seconds dial in contrasting black enamel face sits at seven o’clock.

The movement and the dial sit within holder ring, which contacts the case at the winding crown and is fixed elsewhere to the case by four architectural struts.  The struts and the ring are made from a specially treated alloy that looks like it might have fallen from space itself.

BENU ‘Lost in Space ’is available in a 26-piece limited edition, commemorating the passage of time since Moritz Grossmann’s birth in 1826.
