For 2009 Lange’s classic 1815 is enlarged to 40mm and fitted with a new manual winding movement that fills the case. Though updated for modern tastes, the 1815 remains a classic three-hand watch. The 1815’s name reflects the birth year of company founder Ferdinand Adolph Lange. The solid silver dial features Lange’s traditional railway-track minute scale, Arabic numerals, and small seconds at 6 o’clock, reminiscent of Lange pocket watches of days gone by.
The new caliber L051.1 measures 30.6 x 4.6 mm in and consists of 188 parts, many of which are hand-decorated. The movement’s features include a three-quarter plate made of untreated German silver, a hand-engraved balance cock (of which no two are exactly the same), a whiplash precision index adjuster, 5 screwed gold chatons, and thermally blued screws. The movement runs in 21 jewels at 21,600 semi-oscillations per hour with a 55 hour power reserve.
The new 1815 is available in yellow, white and pink gold, and in a limited edition of 500 pieces in platinum.
