SIHH Debut: TOURBOGRAPH PERPETUAL 

・・・ “Pour le Mérite” (3/4) The TOURBOGRAPH PERPETUAL “Pour le Mérite” follows traditional design and construction principles.
 Arabic numerals, the peripheral minute scale, blue steel hands and diamond endstones are characteristics of the traditional 1815 family. They pay tribute to the famous A. Lange & Söhne pocket watches.
