50th Anniversary Watch With In-House Movement
Dornblueth & Sohn watches have always been very difficult for us to keep in stock.
One of the very factors that makes Dornblueth & Sohn watches so collectible is the same cause of the stocking issue - extremely low production with wait times of up to 18 months.
And the Dornblueth & Sohn Quintus Power Reserve with Dirk's in-house movement is currently the most difficult to obtain.
This watch celebrates Dirk's father 50th anniversary in the watchmaking craft, and more importantly is the culmination of years of research, testing and effort to design and build a new in-house calibre.
The Quintus Power Reserve Design
The Quintus design is smaller than other Dornblueth & Sohn watches, with a case diameter of 38.5 mm rather than the 42 mm case size used on other models.This size makes this watch a perfect fit for those with medium (average) to small wrist sizes.
This watch features the Dornblueth & Sohn Calibre 2010.2 which was both developed and created in-house from Dirk's workshops in Kalbe, Germany.
Among the many amazing features of this new movement is the patent pending double barrel Maltese cross spring providing a linear torque of power to the movement.
In most mechanical watches, the run rate and timekeeping are different when the movement is fully wound in comparison to when it runs down.
Dirk's solution is a 52 hour power reserve system that stabilizes the consumption of power by the watch resulting in more consistent timekeeping regardless of the tension on the main spring.
A Power Reserve Indicator That Really Works
This watch features one of the most accurate power reserve indicators designed for a mechanical watch.
Dirk obsesses over the accuracy of the power reserve display, whose accuracy in most mechanical watches decreases as the main spring releases tension. Dirk has used a different gearing system to design his power reserve indicator and his tests show that the rate of decrease is indeed more linear to the release of tension on the main spring.
Translation: a more accurate way to tell when your watch should be wound.
The movement is beautifully finished and decorated by hand.
The Dornblueth & Sohn Quintus Power Reserve incorporates a Glucydur screw balance with Nivarox-1-Breguet spring along with Swan-neck fine adjustment on hand-engraved balance cock.
As is traditional for watches made in the Glashutte region of Germany, this watch features a 3/4 plate, screwed gold chatons and elaborate hand decoration and finish.
The movement is finished with applied rose gold, while yellow gold is used to indicate the manufactory name and serial number. The front of the watch is fitted with a slightly domed sapphire crystal with interior anti-reflective coating, while the back uses a screwed sapphire back display.
Hand Engraved Dial
The dial is created in-house using the same engraving techniques used to produce old pendulum clocks. The dial surface is finished with a silky matte surface (this finish was applied in historical ship chronometers).
After the dial is engraved, Dirk applies black to the engraved areas for a clear high contrast display. The hour and minute hands are centrally mounted with the seconds display at 6 and power reserve (Auf & Ab) at 12.
In Summary, An Amazing and Rare Watch
This watch represents the very best of Dornblueth & Sohn.
As in all of his watches, Dirk has no CNC computer machines on premises to make his watches. His watches are among the very highest in the industry to use hand workmanship rather than computer code.
And his new in-house calibre 2010.2 is not only an engineering feat but also a beautifully designed, finished and decorated component of the new Quintus Power Reserve.
This watch ships on a black calf leather Dornblueth strap with Dornblueth stamped tang buckle.
