Lange's fourth anniversary edition

A. Lange & Sohne presents the fourth part of their anniversary collection, the Lange 1 Tourbillon Perpetual Calendar “25th anniversary.”

The year 2019 marks the 25thanniversary of the Lange 1 collection by A. Lange & Sohne. To celebrate this momentous occasion, the german luxury watch brand has introduced a ten-part series of new launches of the Lange 1 collection. Today the brand unveiled its fourth model, the Lange 1 Tourbillon Perpetual Calendar “25thAnniversary.”

Presented first in October 1994, the Lange 1 has always been iconic to the brand's legacy. The new 41.9mm comes with a rotating peripheral ring to indicate the month – similar to how it was in the first 2012-edition of the Lange 1 Tourbillon Perpetual Calendar.

The argenté-coloured dial features blued-steel hands, an outsized-date display, and a retrograde day-of-the week display which takes the place of the power reserve indicator. The leap year is displayed in a small aperture at the 6 o'clock position, while the moonphase display can be seen through an aperture on the seconds subdial at the 7 o'clock position.

Equipped with the automatic calibre L082.1, the caseback of the 25thanniversary edition showcases an epigraph at the 12 o'clock position. The 69-part tourbillon comes with the patented stop-seconds mechanism which can be stoped at any time by pulling the crown. The tourbillon cock also comes with a blue engraving of the number 25. This symbolises not only the anniversary, but also points to the fact when the date displays of the debut watches were set to the 25thon the 24thOctober, 1994, so they would be current when showcased in the following day's newspapers.

Limited to 25 pieces, the Lange 1 Tourbillon Perpetual Calendar “25thanniversary” sits comfortably on a hand-stitched blue alligator leather strap with a contrasting grey seam.
