The 1815 Rattrapante Honeygold was released in 2020 as one of three commemorative “Homage to F. A. Lange” watches. Limited to 100 pieces, the split-seconds chronograph featured a black dial with the Honeygold case.
Now, Lange have launched a new variant. Also in a limited edition (this time of 200 pieces), the new 1815 Rattrapante is a boutique-only edition in a 41.2mm platinum case (thickness of 12.6mm) with a silvered dial.
The movement in this new timepiece is the same as in the Honeygold model – the manually-wound in-house L101.2 beating at 21,600 VPH with a power reserve of 58 hours. It features a lever escapement, shock-resistant screw balance, in-house balance spring, precision beat adjustment system with lateral setscrew, and a whiplash spring. Again, the plates are made of untreated German silver, with both the balance cock and chronograph bridge engraved by hand.
This time, the dial is solid silver argenté. The hours, minutes, and small seconds are in blued steel, the 30-minute counter is also in blued steel, the central chronograph hand in rhodiumed steel, and the central rattrapante hand is in blued steel.
For those unfamiliar with split-seconds (rattrapante) chronographs, both chronograph hands start together when you activate the pusher at 2 o’clock. The centre rattrapante hand can be stopped independently of the central chronograph hand, and then re-synchronised with it, to measure elapsed and lap, time. The chronograph movement in this watch has two column wheels.
Coming on a black alligator leather strap with a 950 platinum buckle, the 1815 Rattrapante platinum is boutique-only, with the POA.
