A Lange & Sohne
Richard Lange Jumping Seconds In Pink Gold
The Richard Lange Jumping Seconds made its debut last year in a platinum case, which proved to be an instant hit. This year, German luxury watchmaker A. Lange & Sohne has followed up with a version in pink gold with matching accents on the dial and buckle, also limited to 100 pieces.
The clean, minimalist timepiece boasts an exceptionally complex movement, which pays tribute to watches for scientific observation. It is driven by a one-second constant-force escapement with an integrated jumping mechanism, which ensures accuracy and precision.
The largest sub-dial showcases the blued steel seconds hand. A “zero-reset” mechanism with a multi-disc clutch propels the seconds hand to jump to the zero position when the crown is pulled.
The 39.9mm watch is powered by the manually wound L094.1 manufacture caliber. A small triangular indicator on the dial turns red 10 hours before the 42-hour power reserve runs out, serving as a reminder to rewind the watch.
The intricate constant-force escapement and zero-reset mechanism can be observed through the sapphire-crystal caseback. The aperture reveals how the remontoir spring of the constant-force escapement receives fresh energy from the mainspring barrel every second to power the escapement at the same rate. Just below it, under a transparent jewel bearing, a star connects to the fourth-wheel arbor that controls the jumping seconds sequence.
