What to know
The Friedrich III Power Reserve adds an upper reserve scale to Lang & Heyne’s classical dial. Ceramic, engraved Roman numerals and broad spade hands retain the family’s character, while the prominent small-seconds display balances the new indication. The 39.2mm case preserves the maker’s distinctive triple-lug construction.
The hand-wound Calibre VI-II uses a differential to combine information from the barrel and winding train for the reserve display. It provides 55 hours of running time, with traditional finishing visible through the sapphire back. September 2026 coverage described a 25-piece edition available in rose gold or platinum. The photographs show the rose-gold execution.
