German silver Special alloy composed of copper and zinc, with a nickel concentration of about 10%. German silver is stronger than brass and has been traditionally used by Lange for the manufacture of plates and bridges. The addition of nickel minimises the oxidation of German silver and thus eliminates the need to electroplate the alloy - it can remain "untreated".

Balance cock Small metal plate screwed to the visible side of the movement. It carries the balance wheel shaft bearing.

Blued steel, blued screws Steel parts are slowly and cautiously heated (annealed) to about 300°C. This process coats the metal with an extremely thin, shimmering film of cornflower-blue magnetite (Fe3O4).

Gold chaton The gold setting of a bearing jewel - in Lange watches, chatons are often secured to the three-quarter plate with two or three screws.

Three-quarter plate The three-quarter plate was introduced in Glashütte by Adolph Lange in 1864. Since then, it has been a typical feature of Lange watches. It accommodates the counter-bearings of the going train and enhances the stability of the movement.

Whiplash precision index adjuster An adjusting device composed of a steel spring in the shape of a swan's neck, a pointer, and a setscrew. The screw is used to adjust the beat, or the timing, of the watch in very small increments.

Glashütte ribbing A linear decoration. It is produced by a rotating grinding wheel that is slightly inclined and moved along the surface of the workpiece in parallel lines.

Chamfering Also: angling, bevelling. The breaking and polishing of sharp edges on bridges and levers. The inclined surface has the same width along its entire circumference or length.

Perlage Also: circular graining. Cloud-like decoration on plates and bridges. It is produced by stippling the surface with a small rotating grinding wheel.

Screw balance A balance wheel that has adjustable screws and tiny washers along its rim.

Semi-oscillation Also: vibration. Half of the path travelled by the balance wheel from end point to end point.

Stop seconds Mechanism that stops the balance wheel and thus the movement of the seconds hand when the crown is pulled. This allows a watch to be precisely synchronised with an external time signal.

The movement of the SAXONIA unites nearly all of the elements that stand for the ultimate in quality as interpreted by Lange. One of the most striking typical features is the | three-quarter plate crafted from untreated, cross-laminated | German silver. The | blued screws, the deep red jewels, and the four screwed | gold chatons create noble accents. The | whiplash precision index adjuster is mounted on the small | balance cock; it is hand-engraved, making each SAXONIA a one-of-a-kind treasure. Without exception, all parts of the movement are lavishly decorated by hand, even those that normally remain concealed. No fewer than five decoration techniques are involved. The three-quarter plate is finished with | Glashütte ribbing. Small levers and jumpers are decorated with | straight graining, wheels with | circular graining. The undersides of the plates feature a | perlage pattern, and the spring barrel is finished with solarisation on both sides. Additionally, all the edges in the movement are | chamfered and polished. The manually wound movement with | stop seconds has a power reserve of 45 hours when fully wound. The precious, shock-resistant | screw balance beats at a frequency of 21,600 | semi-oscillations per hour and is adjusted in five | positions.
