With A. Lange & Söhne Proof of Origin dated 7 March 2014 confirming manufacture of the watch and original fitted wooden presentation box no. 100/100 and outer packaging.
Purchased by the actual owner and hardly ever used if at all, the present watch is preserved in close to new overall condition.
A timepiece of extraordinary quality, the Lange 1A pays tribute to A. Lange & Söhne's historic pocketwatches bearing the distinction "1A" for their ultimate craftsmanship.
The present watch, no. 100/100, is the very last example made of the strictly limited edition of only 100 watches of ref. 112.021. Exclusively available in yellow gold and distinguished by the hand engine-turned solid 18K gold dials, the "Lange 1A" commemorates the inauguration of the second Lange manufactory building in 1998. The model was in production between 1998 and 1999 and was immediately sold out.
Of superb workmanship, the movement of the Lange 1A is fitted with a gold escape lever and gold escape wheel for which specially hardened white gold is used as it is much more wear-resistant than yellow gold. The pallet, escape wheel and balance bridges are also in gold and individually engraved by hand. The two tandem-wound mainspring barrels provide a power reserve of at least three days and allow a progressive power reserve indication.
