Description
Dornblüth & Sohn 99.9 Power Reserve (GR) ST
Dornblueth & Sohn’s much-loved Centre Second timepiece has been enhanced with a power reserve gauge to add another level of functionality to this elegant classic.
By positioning the gauge in the lower part of the dial, clarity and legibility are retained. Two options for the indication system are available: a bar indicator creates a bolder statement or an arrow indicator delivers a more understated finish. The chance to further individualise your watch is possible by selecting from either a white or black dial.
Upgrades such as bespoke colour-matched ceramic dials and solid gold cases open the design options for you to fully customise your 99.9 Power Reserve to your exact requirements.
Dornblueth & Sohn’s 99.9 Power Reserve is a classic-looking, functional timepiece with the potential for you to make it your own or take it as it is, in all its German perfection.
