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.
