Dornblueth & Sohn Calibre 99.5 Black Dial

This is one of our favorite watches from Dornblueth & Sohn as it features his most interesting complications - an in-house power reserve indicator, central seconds and date display.

---

To create the Calibre 99.5, Dirk created an elevated central seconds bridge to house the necessary gears for the sweep second function. He also built a hack feature into the movement (the second hand stops when the crown is engaged).

The power reserve indicator is located at 9 with the date at 3 providing balance to the dial.

As is typical in a Dornblueth watch, Dirk includes all the "good stuff" - 3/4 plate, beveled edges, screw balance wheel, swan neck regulation, engraved balance cock, screwed gold chatons, and blued screws (by flame of course, including the slots).

And now the extras. The name "D. Dornblueth & Sohn, Kalbe i./S.A." is hand engraved and not machine engraved, a virtually rarity on any watch. And all of the decoration (Côtes de Genève and the sunray finish on the crown wheel and ratchet) are all done in-house, by hand.

You'll notice that the movement is rose gold in appearance - this process itself is elaborate. After cutting and polishing the plate, Dirk treats the surface to turn the metal a copper color. After all of the drilling and milling operations are complete, the movement itself is treated with rose gold to enhance the deep color.

The dial is black with white printed numerals and markers.

This watch features a brushed and polished nickel-free steel case and the crown is signed D. Dornblueth, as is the tang buckle.

Power reserve is 50 hours.
