A historic engraving technique is being given a new lease of life to mark the manufactory’s anniversary on 11 November 2021. Finished using the eponymous tremblage engraving technique, the TREMBLAGE anniversary model elegantly combines vintage style with the finest mechanics. The timepiece is available in rose gold and stainless steel

Christine Hutter, founder and CEO of the young manufacture, states: “The TREMBLAGE is yet another outstanding innovation in our BENU Heritage collection line. We have revived the historic engraving technique of tremblage in our anniversary model and are delighted to have an engraver with exceptionally long experience and an artistic sensibility to craft a unique work of art from each of our dials.

The dial

Material and surface form a fascinating liaison. German silver is an alloy of copper, nickel and zinc, among others, which is frequently used in historical watches and movements. Thanks to the surface treatment, this alloy produces a silver-like hue with an aesthetic vintage look. The three-dimensional appearance of the dial underscores the effect: The numerals of the hours and circular small seconds rise above the surface, as does the historic “M. Grossmann” logo from 1875, which goes back to Moritz Grossmann, the famous watchmaking pioneer who gave his name to the Glasshütte manufactory.

These are not mounted appliqués. On the contrary, the base of the dial has been cut out and removed so that the logo, numerals and seconds circle remain. A task that also requires meticulous care to create clean edges. The top of the numerals, logo and seconds circle were also given a flat polish finish.

Only then did the dial undergo the painstaking tremblage process in Glashütte, a method that takes numerous hours. A single dial can take an engraver several days to complete. The whole is complemented by the meticulous craftsmanship of the finishers.

The result is exquisite – a uniquely crafted work of art with an even, fine grain that softens the effect of incident light and lends a wonderfully matt appearance to the tremblage surface. The lavishly flat polished raised elements create a lustrous contrast.

The winding crown and the pusher

The gently curved form and the tapered chamfer of the strap lugs enhances the eloquent silhouette of the case.

Aesthetic and functional — the circumferential groove makes it easy to pull out the crown. The pusher for the new handsetting train is set directly below the winding crown.

The butterfly clasp

Centred on the inside of the wrist when worn, the optional available butterfly clasp makes it easy to put on and take off the watch.
