The 1815 Chronograph “Hampton Court Edition” comes in a solid white-gold case with a diameter of 39.5 mm. The black dial features, for the first time, sandstone-coloured numerals and scales.

The tachometer scale on the peripheral – which enables the calculation of average speeds – emphasizes the historic connection between motorsport and time measurement.

The contrasting rhodié-colored subsidiary dials for the small seconds and the minute counter improve readability, also assured by the rhodium case-matched gold hands for the hours and minutes as well as by the rhodium steel hands for the chrono seconds, the subsidiary seconds, and the minute counter.

Behind the solid-gold hinged cuvette with the hand-engraved logo of the Concours of Elegance ticks a manufactory-designed and -produced chronograph movement with a flyback function and column-wheel control. Beating at a frequency of 18,000 vibrations per hour (2.5 Hz), the watch displays stopped times to an accuracy of one-fifth of a second. The power reserve is 60 hours.

As with every Lange movement, the hand-wound caliber L951.5 is assembled twice and finished at the highest quality standards.

The A. Lange & Söhne 1815 Chronograph “Hampton Court Edition” (ref. 414.047) is completed by a black hand-stitched alligator leather strap with a prong buckle in solid white gold.
