Lot Essay
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 is no. 66 of the strictly limited edition of only 100 watches of ref. 112.021, furthermore preserved in excellent overall condition. 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.
