TEFNUT “Twist” Gent White Gold
TEFNUT “Twist” – design innovation
Moritz Grossmann’s stunning TEFNUT collection combines watchmaking excellence with innovation and design.
The innovative “Twist” collection introduces a unique winding system that is cleverly incorporated into the watch design to add functionality without compromising the elegance of the design.
Moritz Grossmann’s master watchmakers met a long-standing challenge when they developed the innovative winding mechanism for the TEFNUT “Twist”. The quest to develop a robust alternative to the conventional crown winder resulted in the exceptional and original solution: The Grossmann strap winder (patent pending) makes it possible to wind the watch hands with just a few turns of the lug/strap attachment at 6 o’clock.
To enable this remarkable development, it was necessary to extensively rework the calibre 102.2 and modify the exterior silhouette of the lugs without detracting from the overall elegance and simplicity of the timepiece. The open lugs and lowered crown setting, that appear to be simply individual design touches, are actually integral technical developments that make the “Twist” model so unique and collectable.
TEFNUT “Twist” is available in 3 distinctive collections: Gent, Classic and Fancy to suit the taste and passion of lovers of fine watches.
The TEFNUT Gent’s collection epitomises streamlined elegance and the reduction of timekeeping to its essence. Its svelte case, available in massive rose or white gold, clear, classical dial design with Arabic numerals, manually-crafted hands, annealed to a brown-violet hue and offset small second dial will appeal to those who appreciate fine watchmaking and understated elegance.
The inclusion of Moritz Grossmann’s unique winding mechanism makes this piece stand out from contemporary designs by adding integrity and watchmaking substance to a very desirable timepiece. This is a watch that will be valued for generations to come.
The TEFNUT Classic collection projects a balanced combination of classical beauty and superb functionality. The case is available in either massive rose or white gold and the lug ends and crown are adorned with precious stone cabochons.
The dial is decorated with a recessed guilloche pattern allowing prominence to the raised hour circle with its crisp numerals. Similarly the small second sub dial, positioned at 7 o’clock, facilitates exact time measurement without cluttering the dial. Hand formed and annealed hands to brown-violet hue set off the off white tone of the argente dial.
The TEFNUT Classic is a perfectly balanced timepiece with all the charm and value of a heritage investment piece.
The crowning glory in the TEFNUT “Twist” collection is the Fancy collection with its strikingly beautiful dial in Mother-of-pearl with diamond highlights.
This piece can be described as a multi-faceted jewellery watch, available in either massive rose gold or white gold. The slender case silhouette, magnificently finished dial and expertly set white brilliant-cut diamonds afford a feminine air to this unique timepiece.
The iridescence of the white mother-of-pearl is finely worked in areas to enhance legibility and design. A radially guilloched passepartout adds prominence to the off-centre second display. The scythe-shaped mother-of-pearl inlay towards the top of the dial showcases 5 prominent Roman Numerals adding a dramatic element to balance the lower half of the dial without complicating the overall design.
TEFNUT “Twist” Fancy ranks among the most exquisite and superbly functional ladies’ wristwatches available today.
