A repeater is a complication in a mechanical A. Lange & Sohne Zeitwerk Striking Time replica watch that audibly chimes the hours and often minutes at the press of a button. Minute Repetition remains one of the major technical challenges in the art of haute horlogerie. Over 400 individual parts of the clockwork movement are put together in excess of more than 140 hours of meticulous work by highly reputed watchmakers.For Milus, this marks a significant milestone in its quest to attain high precision in this iconic timepiece. Pureness of tone and fullness of sound are the challenges faced by the experts. This complication has traditionally been valued as a novelty by A. Lange & Sohne copy watch connoisseurs and aficionados, attracted by the sonorous reporting of time. Minute repeaters have now acquired a character of their own thanks to great advances in sound and horological technology.The Minute Repeater chimes the time down to the minute, using separate tones for hours, quarter hours and minutes.
The attributes of the Milus Tirion Repetition Minutes Retrograde, unveiled at Baselworld 2010 in a limited edition of 50 pieces with its own calibre, is a good case in point. The uniquely curved minute-rack of the calibre has also been turned around and enlarged to achieve greater precision and pureness of tone.
To ensure a pure sound, the gongs must not touch one another. The major challenge for the experienced experts is the adjustment. The length of the gongs as well as the securing of the base to the bottom plate must be adjusted to the desired “a” and “c sharp” notes in several steps.They are produced from a special steel alloy and connected to the same base.
This gives the harmonious major-third unspoiled sound perfection. As every Milus Tirion Repetition Minutes TriRetrograde is manufactured by hand, minimum tone variations can occur here, thus giving each watch a very individual sound. Instead of the classic slide to activate the fascinating mechanism of the minute repetition, the Milus Tirion Repetition Minutes TriRetrograde is equipped with push-piece at 9 o’clock with engraved clef.
