Christian Lass

Christian Lass grew up in Copenhagen and trained at the Danish watchmaking school Den Danske Urmagerskole, including an apprenticeship under Søren Andersen — where he helped maintain timepieces for the Danish royal family.

He then met Vianney Halter and spent several years at Halter's Sainte-Croix workshop, where Halter taught him to make a watch from the ground up. In those same years he spent evenings in the workshop of Philippe Dufour, who told him of a rare opening at Patek Philippe. He became the sole master watchmaker responsible for the entire Patek Philippe Museum collection in Geneva — spending nearly a decade taking historically significant watches apart, restoring Jacques-Frédéric Houriet marine chronometers, Albert Potter pocket chronometers, and many other extraordinary objects. 'That is the best experience I had, working in the museum.' In 2018, with his wife and partner Hannelore, he returned home to Denmark — settling on the island of Fyn — and set up his workshop. Hannelore, who had spent eight years as an engraver at Olivier Vaucher's atelier in Switzerland (engraving early Vianney Halter Classic, Trio, and Antiqua Perpetual dials), is the hand engraver for all Christian Lass timepieces. Together they form one of the most quietly exceptional watchmaking partnerships in the world. Debut: the 30CP (2020) — a time-only watch in 18k gold (38mm, 11.5mm, 42-hour power reserve, 18,000vph) modelled on 1940s gentleman's wristwatches. Christian makes the case, dial, and most of the movement himself, using only the going-train wheels from a Girard-Perregaux cal. 27. German silver bridges and dial, all hand-engraved and lacquered in black by Hannelore. The innovative hairspring adjuster — an arm pivoting on a ruby ball, a miniaturised version of Breguet's marine chronometer regulator — gives precision adjustment with extraordinary delicacy. One-year delivery time, CHF 50,000.

The workshop's philosophy is to use only techniques the couple have mastered with their own hands, and the scope of that mastery keeps widening — Lass even turns his own cases on the lathe, a skill rare enough among independents to be remarked upon. The 30CP is quietly customisable: the standard 38 mm case can be ordered in rose, white, or yellow gold (or enlarged to 40 mm on special request), with dial materials and engraving open to discussion, and the borrowed going-train wheels carry their own history — the Girard-Perregaux cal. 27 donor is based on the AS 1130, the robust mid-century 'Wehrmachtswerk' ébauche that fellow Danish independent Svend Andersen also favoured for its reliability. Hannelore's engraving practice operates under its own name, Gravalance, and her hand-engraved, black-lacquered German silver work has become as much a signature of the watches as the movement architecture itself. The next chapter arrived in 2026, when Lass unveiled the 30CT at Watches and Wonders: years in development, it adapts an entirely new in-house tourbillon calibre — mounted as a 'rear tourbillon' visible through the caseback — to the classical style established by the 30CP, an ambitious step up in complication for a workshop of two, and one that accompanied his candidacy for the AHCI, the academy of independent creative watchmakers. With production holding at roughly ten watches a year from an island workshop that the couple describe simply as somewhere on Fyn, Christian Lass remains one of the purest expressions of the artisan ideal in Northern Europe: museum-trained restoration expertise, Halter and Dufour mentorship, and a family atelier where every watch passes through just four hands.
