INTRODUCING: A. Lange & Söhne 1815 Rattrapante Perpetual Calendar and Lange 1 Time Zone

The A. Lange & Söhne 1815 Rattrapante Perpetual Calendar in white gold with rose gold dial.

The watchmaker presents two special editions for this summer.

At Watches and Wonders Geneva earlier this year, A. Lange & Söhne presented just one watch – the Odysseus Chronograph with the brand’s first self-winding chronograph movement. We all knew that would not be the only release of the year, and sure enough, the Glashütte-based watchmaker has introduced two new editions of existing watches for the summer. Granted, these are new dial variations of existing watches, but they are stunning executions in highly precious materials.

The Lange 1 Time Zone

A. Lange & Söhne has offered customers a world time watch since 2005. Housed in its iconic Lange 1 line, the Lange 1 Time Zone displays the second time zone on a sub-dial at 5 o’clock, with a large date window above it and a world time ring encircling the dial. In 2020, a revision of the watch offered new improvements with a simple day and night indication on both the main time and city time indicators. Turning at a different rate than the hour hand, telling daytime and nighttime is simply seeing if the blue arc and hour hand are aligned.

The new Calibre L141.1 also features an arrow segment pointing to the selected city with a colour aperture that indicates if the time zone uses daylight savings. In addition, an easy synchronisation solution allows the main time to be set independently of the zone-time by uncoupling the wheels when you hold down the time zone adjustment button at 8 o’clock.

The A. Lange & Söhne Lange 1 Time Zone is powered by the L141.1 calibre with an engraved bridge and balance cock.

Existing Lange 1 Time Zone models are in white gold with a black dial or rose gold with an argenté dial. The new model is in 950 platinum, a first for the Lange 1 Time Zone with a rhodium dial. The monochromatic silver-coloured watch has a polished case with curved lugs and is paired with a black alligator leather strap with platinum buckle.

The 1815 Rattrapante Perpetual Calendar

It’s been 10 years since the first 1815 Rattrapante Perpetual Calendar was released. The first version of this great complication was housed in a pink gold case with an argenté dial. What’s always impressive about Anthony de Haas’ creations for A. Lange & Söhne’s high-complication timepieces is the legibility of the dial designs, displaying information in an easy-to-read manner.

The analogue perpetual calendar’s information is shown on just two counters, with day and date at 9 o’clock and month with leap year indication at 3 o’clock. The additional moonphase display is positioned at 6 o’clock with the small seconds counter. It’s a highly accurate lunar display, up to 1 day every 122.6 years. The perpetual calendar function is accurate to 2100, when a leap day adjustment will need to be made.

The caseback of the watch shows the split-seconds chronograph function of the 1815 Rattrapante Perpetual Calendar.

The split-seconds chronograph is displayed on the main dial with two chronograph seconds hands in rose gold and blue. The elapsed minutes display is at 12 o’clock with a power reserve indication in the same sub-dial. Last year, A. Lange & Söhne offered the same watch in platinum, with a rhodium dial and in 2023, a white gold version with rose gold (not salmon) dial is available in a limited production of 100 pieces.

This is just the third Lange watch with a rose gold dial. Other models include the Datograph Perpetual Tourbillon and Lange 1 Perpetual Calendar, which were limited to 100 and 150 pieces, respectively. It’s an incredible timepiece that looks even more handsome with a rose gold display. The watch is powered by the same L101.1 calibre, which can be viewed through the exhibition caseback, with the split-seconds chronograph’s functions fully visible – activating a chronograph watch on the reverse has never been more captivating than this.   

Both watches can be ordered through A. Lange & Söhne’s boutiques in Southeast Asia; visit one today to discover them yourself.
