Dornblueth & Sohn’s timepieces are renowned for their classical appearance, precise, in-house movements, and exquisite craftsmanship. The calibre 99 collections epitomise these traits and present various complications with Dornblueth’s DNA and signature finish.
The 99.3 forms part of the classic collection with centred hour & minute hand, a power reserve gauge at 12 o’clock, an enlarged small second sub dial set at 9 o’clock and a date wheel at 3 o’clock. Whether you opt for a light or dark dial in a polished steel or massive rose gold case, with or without applied indices or bespoke finishes, Dornblueth’s 99.3 calibre presents a lot of information in an uncluttered fashion in order to retain the Classic style for which Dornblueth & Sohn is renowned.
The Caliber • The birth of the idea behind the 99.3 complication was born whilst finalising the development of the in-house Caliber 99.2. Even at that time, Master Watchmkers Dieter and Dirk Dornblueth dreamt of integrating an additional complication – the date. Both masters knew this would require time to develop and call for a special dial treatment to ensure balance and legibility – so it was back to the drawing board. The result of their development is the Caliber 99.3 which unites the large eccentric second of the Caliber 99.1, the 99.2 power reserve complcaition and the new inclusion of the date display.
