TRADITIONAL DECORATIONS OF AN A. LANGE & SÖHNE WATCH.

The artistic finesse of watch movements has an impressive role model: Lange’s classic pocket watches. Their balanced design appeals to the timeless human penchant for harmony and elegance. Lange’s master watchmakers reinterpret this paragon of beauty in the manufactory’s wristwatches. And indeed, they radiate the same splendour as their historic forebears.

GLASHÜTTE RIBBING.

The uniform stripes of the Glashütte ribbing pattern decorate the three-quarter plate and the caseback sides of the bridges of a Lange calibre. They are produced by a slightly inclined, rotating grinding wheel that is guided along the component in straight, parallel lines.

The spiral arms of Glashütte solarisation

GLASHÜTTE SOLARISATION.

The spiral arms of Glashütte solarisation constitute a decorative finish applied principally to mainspring barrels and other larger round sur-faces or wheels. The pattern is produced by rotating the part and the grinding wheel in opposite directions.

Perlage

PERLAGE.

Perlage is applied to the inside surfaces of plates and bridges as well as on the invisible dial side of the main plate. The cloudlike decoration is generated with a rotating abrasive peg that only briefly stipples the component. Perlage progresses from the outside to the inside of a part, and each stipple overlaps the previous one.

Straight graining

STRAIGHT GRAINING.

Straight graining is a finish applied especially to steel clicks, springs, and yokes. This type of decoration is produced with abrasive paper across which the part is drawn in a longitudinal direction. The tech-nique calls for straight but cautious movements to assure that the delicate linear pattern is applied even to the furthermost corners of
the component.

Circular graining

CIRCULAR GRAINING.

Smaller wheels are finished with circular graining. The regular circular contours are produced when the part is rotated on abrasive paper.

Circumferential polishing

CIRCUMFERENTIAL POLISHING.

This technique is used to embellish the vertical edges of the frame elements of a Lange movement. The finish is applied with a rotating abrasive peg. The part is manually pressed against the side of the abrasive peg.
