Four years ago, with the Odysseus, the A. Lange & Söhne watchmakers launched their first sporty-elegant timepiece, showcasing a unique design and a customised, exquisitely finished movement. Now, the Odysseus Chronograph is the sequel to the success story of this watch family. The newly developed L156.1 calibre encased in stainless steel premieres: it is the first A. Lange & Söhne self-winding chronograph movement. Thanks to its innovative and dynamic function that resets the chronograph hands to zero, this timepiece is proof that the Saxon manufactory dauntlessly explores new avenues and advances the development of precision watchmaking. Given its horological intricacy, the Odysseus Chronograph comes in a limited edition of 100 watches.
The challenge of a manufacture movement
To retain the characteristic dial design of the Odysseus, the manufactory developed a customised movement that positions both chronograph hands in the centre, the minute counter with a lozenge-shaped tip as well as the red chrono seconds hand. As a consequence, the totalisers, which are conventionally arranged at 3 and 9 o’clock, could be dispensed with, and the style-defining positions of the outsize date and day of the week could be maintained.
Owing to the expansion of the measuring range from 30 to 60 minutes, the Lange developers succeeded in introducing new fields of application for the chronograph. Additionally, it is endowed with an innovative, dynamic reset-to-zero function. When the reset-to-zero button at 4 o’clock is actuated after a time measurement, a short but impressive spectacle ensues: while the minute counter jumps back to its starting position in the conventional way, the red chrono seconds hand covers the entire distance travelled beforehand within a fraction of a second ‒ one full revolution for each measured minute. If the minute counter has not reached the 30- minute mark yet, the two hands move anti-clockwise. If the minute counter has passed the 30- minute mark, both hands will advance to zero clockwise. At high speed, the chrono seconds hand performs a full revolution for every minute required to reach the full hour.
Dual-function button
To assure safe and easy operation of the chronograph, the Lange product developers equipped the specially sealed, tapered buttons with a novel dual function. In the normal position of the screw-down crown, the buttons at 2 and 4 o’clock are used to operate the chronograph functions: start, stop and reset to zero. When the crown is pulled, the date and day of the week can be corrected with a newly developed mechanism.
A distinctive design
The Odysseus Chronograph takes centre stage in a three-part stainless-steel case with a diameter of 42.5 millimetres that withstands a test pressure of 12 bar and is robust enough to accompany its wearer even during sports and leisure activities. As with the other members of the watch family, the surfaces are matted and the edges are accentuated with a chamfer: the combination of brushed surfaces and chamfered edges creates an impressive play of light and is echoed on the lugs and links of the solid stainless-steel bracelet.
The proprietary path to perfection
The L156.1 DATOMATIC calibre ‒ the manufactory’s first self-winding chronograph movement ‒ powers the Odysseus Chronograph. The attribute DATOMATIC is derived from the words “date” and “automatic”. A skeletonised and partially black-rhodiumed central rotor with a centrifugal mass in 950 platinum assures efficient winding. When fully wound, the mainspring barrel delivers a maximum power reserve of 50 hours. The oscillation system is designed to ensure optimum rate accuracy. To this end, the balance, which beats at a frequency of 28,800 semi-oscillations per hour (4 hertz), was suspended beneath the balance bridge; it is hand-engraved with a stylised wave pattern alluding to the water resistance of the watch and the possible applications in sports settings.
