A. Lange & Söhne represents the pinnacle of German high watchmaking, where every case, dial, and movement component reflects an uncompromising approach to precision and finishing. Most Lange watches are crafted in precious metals such as rose gold, white gold, or platinum—materials chosen for their beauty rather than hardness. Designed for refined daily wear, these watches invite close inspection, making surface condition an essential part of their overall value and presence.
Unlike steel, gold and platinum are inherently soft. Even careful daily wear can result in hairline scratches on bezels, case sides, and lugs. Because Lange cases are defined by subtle curves and crisp transitions, polishing removes not just scratches but also original geometry. Once altered, these fine proportions cannot be fully restored, which is why collectors place such importance on unpolished examples.
From a long-term collector’s standpoint, preventive protection offers an alternative to future refinishing. By creating a physical barrier between daily friction and the case surface, owners can preserve the original metal volume, finishing contrasts, and factory lines—maintaining both aesthetic integrity and long-term collectability.
