A. Lange & Söhne presents a special edition LANGE 1 TOURBILLON timepiece as the final piece of the ten-part special series that celebrates the 25th anniversary of the iconic LANGE 1 timepiece.
The LANGE 1 TOURBILLON had its debut in 2000. It is the world’s first wristwatch with the unusual combination of a tourbillon, an outsize date, a three day movement and a power-reserve indicator. Celebrating the 25th anniversary of the LANGE 1 family, the new LANGE 1 TOURBILLON comes in a 25-watch limited edition in white gold.
Introduced in 2010, as part of the “165 Years – Homage to F.A. Lange” anniversary collection, the LANGE 1 TOURBILLON was one of the first three watches of the manufactory with a case in honey gold, a material used exclusively by Lange. When the LANGE 1 celebrated its 20th birthday in 2014, it was introduced as the fourth model of the HANDWERKSKUNST series in a limited edition of 20 platinum-cased watches with rare movement decorations and a black enamel dial.
Like all ten special editions of the anniversary collection, the 2019 version of the LANGE 1 TOURBILLON is presented in silver and blue. The 38.5-millimetre white-gold case sets the stage for a solid-silver, argenté- coloured dial that contrasts with the blued steel hands.
The inscriptions are printed in blue, including the numerals of the outsize date. Suspended between two diamond endstones, the one-minute tourbillon features a stopseconds mechanism. The patented system allows the balance inside the rotating tourbillon cage to be stopped instantaneously. It is clearly visible in a generous aperture in the dial and through the glass units disc of the outsize date.
The tourbillon cock, prominently integrated in the dial, is decorated with the black polishing technique. On the movement side, the tourbillon bridge and the intermediate wheel cock are engraved by hand. The colour concept is echoed in the blue-filled recesses of the engraving.
The unifying anniversary collection signature, a reliefed depiction of the outsize date, is located on the intermediate wheel cock.
