This beauty is one of four new watches that A. Lange will be unveiling at Watches & Wonders which starts one week from today in Hong Kong. Since 2010, the 1815 Chronograph has been a member of the Lange family, with two references now on offer (402.032 pink gold & 402.026 white gold). This particular 1815 Chronograph (Ref 414.026) pays tribute to the 200th birthday of F. A. Lange with an exclusive case-and-dial combination. The special white gold model features blue numerals and a pulsometer scale, along with flyback chronograph. It will be available exclusively in any one of that 15 A. Lange & Söhne Boutiques worldwide.
