Notes

A three-arm polished steel tourbillon of early Swiss design, which appears to have influenced Lange’s inaugural model, driven by the third wheel. This exceptional piece represents a direct precursor to the renowned Lange 1 tourbillon cage, illustrating the early mastery of precision and craftsmanship that would define Lange’s legacy.
