The Mechanical Heart
At our heart is a hand-wound movement of rare pedigree – the L43.1 Calibre based on a 1960s Marvin 700 movement.
It has a diameter of 29.4mm and a thickness of just 3.2mm which contributes to our elegantly thin case profile. It‘s large balance wheel beats at 21,600 vibrations per hour and has a power reserve of 46 hours when fully wound.
The L43.1 Calibre
In honour of Gerd-Rüdiger Lang’s decision to reveal the mechanics through transparent display casebacks, the outline and finishings of the L43.1 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.
