A further jewellery watch for the TEFNUT family was the result of a joint venture between two worlds: an imaginative motif created by award-winning designer Michael Koh from Singapore paired with the pure watchmaking artistry of the Grossmann manufacture in Glashütte. Michael Koh‘s passion is exceptional precious stones that he showcases in unique ways. His creations tell mystical stories – the TEFNUT Sleeping Beauty leads us to the secretive world of the moon.

Despite its grace and compact size with a diameter of 26 mm and a height of merely 4 mm, the modified calibre 102.0 sets the stage for a fairy-tale scene. The classic pillar movement with the 3/5 plate embodies characteristic Grossmann calibre elements such as the cantilevered balance cock, the Grossmann poising screws, the raised chatons, the separately removable winder module, and the mass-optimised Grossmann balance.

The Case

The Case

The case of the TEFNUT Sleeping Beauty was artistically modified to accommodate the asymmetric dial architecture. From the crown to the 9 o‘clock side, the case height rises to form a sculpted point of departure for the lugs that end in gently rounded
tips. On the right-hand side, the lugs are freely suspended and like the crown are graced with an iolite or garnet cabochon.

The bezel is set with precious stones that orchestrate in interplay of colours of the case, strap, and dial. The case versions in white gold are set with white, yellow or ocean blue brilliantcut diamonds. White brilliant-cut diamonds deliver the sparking contrast in the rose-gold version.

A gently shimmering satin strap is coordinated with the dial, rounding out the exquisiteness and feminine grace of this jewellery watch.

THE DIAL

THE DIAL

A glance at the TEFNUT SleepingBeauty is an invitation to dream. The four-part dial symbolises the earth‘s companion. The Roman numerals atthe periphery are already halfway coveredby a radiant guilloche pattern. Matching the bezel, the off-centre eclipse is set with an array of sparkling gems.

As a crowning touch, Michael Koh signs the dial with a storybook portrait of the moon, naming his creation „Sleeping Beauty“ as a reference to the nocturnal hour of its completion.

The Hands

The Hands

Specially developed for the TEFNUT family, the hands harmonise in their finesse with the multi-faceted face of the watch. A node that tapers toward the eye of the hand and narrows to a fine point at the tip characterises their shape. The hour hand of the TEFNUT Sleeping Beauty features its very own romantically curved form with an aperture.

This set of hands is the result of many process steps in the manufacture; when complete, they are annealed to the characteristic brown-violet hue. The unique hands crown this timekeeping gem that deserves a place on the wrist of the night owl and the avowed romanticist alike.

The Artist

The Artist

Michael Koh is a painter, a sculptor, and one of Singapore‘s leading jewellery designers. He transforms art into jewellery, and jewellery into art. Exceptional precious stones are his big passion. On trips to mines all over the world, he collects the rarest and most beautiful stones that make the hearts of enthusiasts skip a beat. Michael Koh‘s creations are poetry turned into
jewellery. He names them „In Europe with Love“, „Gardens by the Bay“ or „TEFNUT Sleeping Beauty“.

When he was just 18, Michael Koh was the youngest jewellery designer to receive the Diamond of Distinction Award 1990 and the Young Designer Award. These distinctions were followed by the Hong Kong Diamond Design Award, the Diamond International Design Competition Award and many more. In 2004, Michael Koh established his manufacture and began to market his own brand: In 2016, Caratell was picked as a Top Ten Luxury Jewellery Brand in Singapore.
