Johannes Czapp Danzig Chronometer Maker Kriegsmarine
Share
Johannes Czap was a German watchmaker from Danzig who founded the brand in the late 1800s.
The workshop mainly produced pocket watches, which were known for their high precision and fine workmanship.
The Czap watchmaking family was also connected with the later founding of Patek Philippe, as François Czap (Johannes' relative) was one of the brand's co-founders.
Typical clock movements:
Hand-wound pocket watches:
Caliber: Mostly with German or Swiss hand-wound movements (e.g., from A. Schild, Felsa, Unitas).
Time period: These works typically date from the 1880s to the 1920s.
Earlier works: Some Czap watches (especially from the early days of the brand) used in-house calibers or very fine handcrafted calibers.
High-quality pocket watches from this period (around 1900) often had decorated movements.
Other watch types:
-
Pocket watches (late 1800s to early 1900s)
-
Wristwatches (from the 1920s, but rarely until the 1940s)
-
Chronometers (highest precision watches), especially in the 19th century.
Housing technology & housing materials
Gold case (585, 750) → often 1890–1930
Silver case → common from 1880 onwards, especially very typical from 1870–1910
Chrome-plated brass (on lower-quality models) → from around 1900
Dial design and engravings
Earlier dials (1880–1910):
Elegant, classic fonts, often with capital letters or very fine engraving.
Manual painting and decoration was common.
1900–1930:
Dial faces tend towards simpler designs.
Applied indices and more frequent dial engravings.
“Johannes Czap Danzig” often appears as clear lettering, without the distinctive logo.
1920–1940:
More modern dial designs.
Greater technical precision through new manufacturing processes.
Style and shape of the watch
Pocket watches: Very typical until the 1920s.
Shape: Round cases, bulbous cases (for pocket watches).
Wristwatches: Less common, but increasing after World War I.
Transition from pocket watch to wristwatch.
Flat case shapes with a thinner diameter (during the 1920s–1930s).
Luminescent material and materials
Radium luminous material (on numerals and hands) was particularly typical from the 1920s to the 1950s.
Tritium (from about 1955 onwards), less likely in older Czap watches.
The most common periods for "Johannes Czap" watches
1880s to 1910s:
The first phase of Johannes Czap's work was characterized by high-quality pocket watches and precise movements.
These watches are rare, but extremely valuable to collectors.
1910 to 1930:
This period was the pinnacle for many manufacturers. Johannes Czap produced ornate pocket watches with precisely engraved dials during this time.
1930 to 1950:
Rarely, but still some wristwatches with high-quality Swiss movements.
The transition to the wristwatch could be observed from the 1920s onwards.
Conclusion
Johannes Czap was a respected watchmaker in Danzig who offered high quality and precision.
Age determination is carried out via:
Type of work
Housing material
Dial design
Movement type (hand-wound, in-house caliber, or Swiss movements)
Typical time periods for Czap watches:
1880–1910 (pocket watches)
1910–1930 (pocket watches, transition to wristwatches)
1930–1950 (rare wristwatches, precision mechanical works)
Johannes Czapp Danzig
In 1900, Johannes Czapp was still a watchmaker's assistant in Danzig, residing at Baumgartch Gasse 28. He was not listed in the Danzig address book in 1903 , but in 1904 he was still a watchmaker's assistant, this time at Breitgasse 60. In 1905, he established his watchmaking business at Heilige-Geist-Gasse 31. By 1907 , his shop was located at Kohlengasse 5. His residence was at Holzmarkt 2. In 1922, he was recorded at Heilige-Geist-Gasse 130 with telephone number 3794. In 1933 , Czapp was listed at Jopengasse 69, but a year later his business was located at Heilige-Geist-Gasse 132. In 1935 , his business at Heilige-Geist-Gasse 132 was taken over by Otto Schartner , who lived at Hirschgasse 21. The company's telephone number at the time was 259 91. A year later, Schartner was living in Schwarzsee.
Czapp manufactured ship's clocks for the Imperial German Navy. These clocks were assembled exclusively for the navy by several watchmakers, including A. Schuchmann in Wilhelmshaven (owned by Fritz Schuchmann) , Fritz Tietz , and Franz Happe in Kiel. Several ship's clocks were fitted with high-quality movements by Gustav Becker . Wilhelmshaven, Kiel, and Danzig (now Gdansk) were also the German ports with Imperial naval shipyards during World War I, providing access to the North Sea, the Scandinavian Belt, and the open Baltic Sea. Near Danzig, the watchmaker Theodor Staebe worked in Elbing. He, too, assembled ship's clocks for the Imperial German Navy.
According to a genealogical source, this could possibly be Johann Czapp, who was born in Putzig in 1886. He was the son of Franz Carl Czapp and Maria Elisabeth (Louise) Kollek. Putzig, now Puck in Poland, is about 30 kilometers from Gdansk.
