SIHH 2010: A. Lange & Sohne Lange 1 Tourbillon with stop secondsAlong with the new 1815 Moonphase model, the A. Lange & Sohne Lange 1 Tourbillon watch belongs to the gorgeous Homage to F.A.Lange collection.Perfectly executed and decorated, the watch also features a unique L961.2 manufacture caliber with a one minute tourbillon with stop seconds function.As you probably know, all tourbillon watches have a serious disadvantage: due to their nature, these little pieces of technical marvel could not be stopped, making it impossible to set the watch to the second. Lange’s new invention, a stop seconds mechanism, successfully overcomes this flaw.Made in honey-colored hard-to-scratch gold, the watch will be available only in a limited lot of 150 pieces. Recommended street price and delivery date are yet to be announced.

Among other amazing creations unveiled by A. Lange & Sohne at this year’s SIHH watch exhibition in Geneva was this beautiful Saxonia Annual Calendar.A. Lange & Sohne Saxonia Annual CalendarAvailable in either pink or white gold 38.5mm case, this piece is certainly easy on the eye, due to the unfussy layout of the solid silver dial and the use of oxidized blued steel hands (or rhodiumized pink gold on the pink gold version). It features the familiar outsize date windows at the 12 o’clock positon with month and weekday displayed at the 3 and 9 respectively. The subsidiary seconds share the subdial at the 6 with the moonphase display, which according to the manufacture will require no correction for 122 years! Must make a date in my diary….A.
