LANG 1943 timepieces are powered by a movement with a rare pedigree, the hand-wound LANG 1943 calibre based on a 1960s Marvin 700 ebauche. 

It has a diameter of 29mm and a thickness of just 3.2mm which contributes to the elegantly thin watch profile. Its large balance wheel beats at 21,600 vibrations per hour and has a power reserve of 46 hours when fully wound. 


In honour of Gerd-Rüdiger Lang’s decision to reveal the mechanics through transparent display casebacks, the outline and finishings of the LANG 1943 calibre had to live up to his passion for beautiful and visible mechanics and his uncompromising commitment to quality. 

The decoration of the calibre includes polished screws, polished jewel sinks, straight Côtes de Genève decoration and superb anglage on the beautifully shaped bridges. The crown and ratchet wheels feature sunray brushing.
