The Story about Walther Chronometerwerke

- The marine chronometer wristwatch -

In the tradition of old marine chronometer, this watch was designed as a maritime watch and is built on a small scale, in small numbers, in Germany.

Features of the watch:

- Dial-manufacturing: complex in-house production
- Hand-polished and blue-tempered pointer: in-house production
- Mechanical, historical movement Unitas 6325
- Watchmaking craftsmanship in Germany

History of the watch:
When visiting a marine chronometer exhibition in the German Maritime Museum in Bremerhaven, Juergen Walther had a strong desire to revisit the design of this historic maritime clocks in the form of a wristwatch.


His partner for the implementation of the idea, he quickly found in the person of Rainer Nienaber, master watchmaker and AHCI member, whom he had met several years earlier and had come to appreciate. Initially planned as a watch only for personal use, it quickly got a great acceptance of the project at other watch lovers significantly and the two decided to make the watch in small series.


In addition to the design-fidelity, the watch should be distinguished by a historic hand-wound caliber and the artisanal production of the whole watch:

The marine chronometer wristwatch, produced in small series in Germany.



The watch is built by master watchmaker and AHCI member
(Académie Horlogère Créateurs Des Independants)
Rainer Nienaber, Bünde / Westphalia.
