| The surface of every single part of a Lange movement is painstakingly finished. Lange's master watchmakers decorate even those surfaces that are never visible to the human eye when the movement is completely assembled. Thus, all movement | plates are circular-grained on both sides. On its exposed side, the | three-quarter plate is decorated with several engravings that are subsequently gold-plated. But the finishing touches take place later, in many separate steps. |

Master engravers use free-hand techniques to embellish the small | balance cocks of Lange watches, transforming them into one-of-a-kind timepieces. Lange's engravers all have their personal styles, not unlike an individual signature. That is why they also craft their tools themselves, customising them to the size of their hand and to their preferred engraving technique. |

In addition to these time-consuming finishing and engraving processes, the edges of the movement are | chamfered and polished. It takes up to two hours of highly concentrated work to make an endpiece of the escape wheel, a whiplash spring, and other tiny parts shine like mirrors. Steel levers and wheels are artistically adorned with decorative ground patterns. And specialists with a particularly sensitive feel solarise the remaining untreated surfaces. |
