Hitting the world of horology can often seem like an intricate maze of elegance, craftsmanship and innovation – yet when something like A. Lange & Sohne’s 1815 Rattrapante Perpetual Calendar makes an appearance, its worth becomes abundantly clear!

Recently launched on July 14th 2023, this isn’t your average timepiece: it’s a boutique exclusive limited edition of only 100 pieces, making it one of the rarest pieces in mainstream luxury watchmaking. For watch enthusiasts who appreciate complex complications, this piece serves as an exceptional showcase; three sophisticated watchmaking complications come together seamlessly in an incredible display that truly is captivating.

This watch’s masterpiece lies in its ability to combine a rattrapante chronograph – more commonly known as a split-seconds chronograph – and perpetual calendar seamlessly, no small feat! Completing this intricate machinery is a newly designed 18kt white gold case whose rose gold dial stands out beautifully against it, exuding classic charm that is unmistakably Lange.

As for tech enthusiasts, let’s go deeper. The case in pristine 18kt white gold measures 41.9mm by 14.7mm and features double sapphire crystals for protection. Furthermore, this watch boasts impressive functionality by housing separate correctors for date, weekday/month/moonphase functions.

At the core of this masterpiece beats the German manual-wind Lange caliber L101.1 movement containing 43 jewels, ticking at 21,600 vph, and boasting an ample power reserve of 42 hours. This movement stands as testimony to Lange’s commitment to perfection; meticulous hand decoration and assembly by master craftspeople as well as in-house manufactured balance spring, precision adjustment with five positions adjustment capability and hand engraved balance cock are hallmarks of craftsmanship!

The dial, crafted of solid rose gold, seamlessly coordinates with its rhodiumed gold hands and appliques, while its blued steel hour, minute, and other hands add further sophistication. A rhodiumed steel chronograph hand adds yet another mark of excellence.

Hand-stitched dark brown alligator leather strap with an 18kt white gold deployant buckle adorn this magnificent timepiece and ensure it remains safely on your wrist.

A. Lange & Sohne’s 1815 Rattrapante Perpetual Calendar stands as more than just another timepiece; it represents their tribute to watchmaking’s timeless art, pushing boundaries forward while commemorating their unrivaled legacy within luxury timepieces.

Due to the unpredictable and volatile market on certain Rolex, Patek Philippe and Audemars Piguet watches, prices are subject to change.
