As if Lange did not already offer enough split-seconds chronograph variations — not happy resting on its laurels — they’ve introduced yet another.

The 1815 Rattrapante Honeygold is the latest high-tech chronograph with old school craftsmanship and finishing from one of the world’s foremost chronograph makers, Glashütte-based A. Lange & Söhne. Whether it’s the 1815 Flyback, the Datograph Flyback, the Double Split Flyback, or the Triple-Split — Lange produces some of the most immaculately finished chronographs on the planet.

Presented in a 41.2 mm diameter 18K honey-colored gold case with a black dial in solid silver with gilt markings and gold-plated hands — the A. Lange & Söhne 1815 Rattrapante Honeygold is the company’s sixth split-seconds chronograph and its first watch to offer the combination of a chronograph and rattrapante. This new split-seconds chronograph does not offer a flyback function and is a single split, not a double or triple — but less is sometimes more and it’s to use and read than the more complicated models.

A rattrapante (split-seconds chronograph) features two chronograph seconds hands which make it possible to time one event and then to time a second event (or laps) simultaneously without stopping the timing of the first event.

The chronograph seconds hand (the lower hand within the stack) is made of pink-gold-plated steel. Superimposed above it is the split-seconds chronograph hand, made of rhodium-plated steel. Both hands start together when the pusher at two o’clock is actuated. The rattrapante sweep-seconds hand can be stopped independently of the chronograph sweep-seconds hand and then resynchronized with it, using the extra pusher at 10 o’clock (not found on standard chronographs). If actuated during an ongoing measurement, the rattrapante sweep-seconds hand stops and displays the lap time while the chronograph sweep-seconds hand keeps running. A second actuation of the pusher causes the rattrapante sweep-seconds hand to catch up and then synchronize with the chronograph sweep seconds hand. This lap-time measurement procedure can be repeated as many times as needed.

Lange caliber L101.2

To bring the new rattrapante chronograph to fruition watchmakers at Lange created the new manually wound in-house caliber L101.2. As with the company’s abovementioned split-second offerings, this too requires two column-wheels. And like with the rattrapante clamp that blocks the rattrapante hand in the lap-time display mode, it’s all visible through the sapphire-crystal caseback.

Consisting of 365 total components, 4 gold chatons, and 36 jewels, when fully wound this 3Hz movement can run for up to 58-hours and is regulated by a screwed balance system and lever escapement.

From screwed gold chatons to the hand-engraved balance cock to the chamfered and polished components and the intricately decorated levers, springs, jumpers — every surface is finished to perfection.

The A. Lange & Söhne 1815 Rattrapante Honeygold “Homage to F. A. Lange” is limited to 100 pieces. (Ref. 425.050) Retail is $134,100.
