A. Lange & Söhne, Glashütte i/SA, "LANGE 1 TOURBILLON PERPETUAL CALENDAR", Movement No. 98846, Case No. 202131, Ref. 720.025F, Lange automatic manufacture calibre L082.1, 41,9 mm, circa 2013
An important automatic Glashuette wristwatch in new condition, with tourbillon with patented stop-seconds mechanism visible on the back side, perpetual calendar with outsize date, retrograde day-of-week display, peripheral month ring and leap-year display, day/night indicator and moon phase - limited platinum edition no. 25 of 100 - with original box and integrated watch winder, Lange-booklet, Lange- guarantee seal dated July 9, 2013, operating instructions, setting pin, loupe, cleaning cloth and original sales tag
Case: platinum, screwed on sapphire glazed back, recessed pushers for adjusting all of the calendar indications or for individual corrections of month, weekday and moon phase, Lange platinum deployant clasp. Dial: solid silver, argenté, eccentric Roman hours, auxiliary seconds, large double window for date, white gold leaf hands. Movm.: one-way winding 21k gold and platinum microrotor winding, 5 adj., 75 rubies and 1 diamond, screwed gold chatons, balance with in-house balance spring, hand-engraved balance cock.
To prevent any impairment of the good legibility of the dial, the tourbillon mechanism with the patented stop-seconds function is visible only from the caseback side of the "LANGE 1 TOURBILLON PERPETUAL CALENDAR". The relief-engraved tourbillon and intermediate wheel cocks frame the tourbillon ensemble that is composed of 69 individual parts. The large central rotor in 21-carat gold with a platinum centrifugal mass generates a fully-wound power reserve of 50 hours. Each of the three train bridges is embellished with solarisation. On the front the calendar displays with the patented peripheral month ring are harmoniously embedded in the dial. It delivers at-a-glance readings of the date, day of week, month, leap year and moon phases. All indications of the perpetual calendar - oversized date, retrograde weekday, month ring, leap year and moon phase indication - switch instantaneously and therefore always delivers a doubt-free reading.
