SIHH 2019: A. Lange & Söhne Refines Classic Complications

In addition to the commemorative 25th Anniversary Edition Lange 1 we showed you last week prior to the start of SIHH 2019, A. Lange & Söhne this week debuts a white gold edition of its Richard Lange Jumping Seconds, a Zeitwerk Date with a new date function, a Langematik Perpetual with a new proprietary Honeygold case and a Datograph Perpetual Tourbillon with a sexy new pink gold dial and white gold case.

Richard Lange Jumping Seconds

Now boasting a white-gold case and a black dial, this jumping seconds watch (which debuted in 2016) now adds a set of red color accents that do more than simply please the eye. The regulator dial here, with a large seconds circle at the top and the smaller hour and minute circles arranged beneath it, now also focuses the eye on a red triangle, but only when the watch needs to be rewound.

The new display in the lower zone (where the hour and minute indications intersect) will switch from white to red ten hours before the watch will run out of power to subtly remind the wearer that the watch needs to be rewound soon.

The watch, designed with the firm’s historic observatory watches in mind, retains its 39.9mm diameter and all the technical proficiency of the earlier model, notably its stop-seconds and zero reset function.

Zeitwerk Date

Ten years after first debuting Zeitwerk, its first mechanical wristwatch with jumping digital display, A. Lange & Söhne in 2019 presents a new version of the watch, now endowed with a new manufacture caliber featuring an extra function. On this latest model, the date is displayed via a round disc that circles the dial, magically highlighting the current date in red.

To perform this technical feat, A.Lange & Söhne watchmakers first realized that the Zeitwerk’s large numeral discs and bridges made it impossible to integrate a conventional date indicator. So, the watchmakers arrived at a totally new design to reach this goal. Here’s how it works: The circumferential date ring consists of glass with printed numerals from 1 to 31. To reach the date display in red, a small color segment beneath the date ring moves exactly at midnight. In each month it rotates around the dial once.

The current date always appears red on the new Zeitwerk Date.

The date display can be adjusted with the corrector at 8 o'clock. Also new: the hour indicator can be advanced using a newly developed mechanism, which is activated using the pusher at 4 o’clock.

The new Zeitwerk Date comes in a 44.2-millimeter white-gold case with a grey dial and the aforementioned red date.

All 516 components of the new A. Lange & Söhne Zeitwerk Date are beautifully finished, with many of them (including the engraved ratchet wheel and the filigreed remontoir bridge) visible through the sapphire-crystal caseback.

Langematik Perpetual Honeygold

Each watch in this 100-piece limited edition is being cased in A. Lange & Söhne’s own gold alloy called Honeygold, a metal the company reserves for select models. The alloy is more resistant to wear than other gold alloys, according to the company. The watch’s bezel and prominent strap lugs are polished to create a mirror effect while the middle segment of the contoured case is finished with straight graining.

The new Langmatik Perpetual Honeygold

The Langematik Perpetual Honeygold performs its timekeeping duties by displaying the correct date every day until the year 2100.

You may recall that when the first Langematik Perpetual was introduced in 2001, it was the world’s first self-winding wristwatch that combined an outsize-date display and a perpetual calendar. This latest iteration includes those same features, and also notably the zero-reset mechanism patented in 2000. When the crown is pulled out, this stops the balance and advances the seconds hand to the zero position, which simplifies time setting.

Despite its complexity, the 38.5mm-wide watch is a comfortable 10.2mm thick. The solid-silver dial contrasts highly with the luminous hands as well as the applied Roman numerals, also in honey gold.

Datograph Perpetual Tourbillon

Launched in 2016, the Datograph Perpetual Tourbillon combined a flyback chronograph, a perpetual calendar with moonphases, a tourbillon with stop seconds, and a power-reserve indicator into one handsome package.

Debuted in platinum at that time, this year A. Lange & Söhne presents the watch with a white gold case for the first time, and enhances the offering with an alluring pink gold dial.

You might recall that A. Lange & Söhne uses the term ‘Datograph’ to refer to a flyback chronograph with a precisely jumping minute counter and the well-known Lange outsize date. This new model also features that perpetual calendar, boasting jumping displays combined with a moon-phase indication calculated to remain accurate for 122.6 years.

The tourbillon here refers to the one-minute tourbillon with patented stop seconds that is visible, unusually, only on the caseback side.

Directly on the dial you’ll see time, calendar and chronograph displays is rounded off with a power-reserve indicator at the end of the tachymeter scale. As with its platinum-cased forebear, this is a limited edition of 100 watches.
