The marine observation clock in the picture is an example of a clock whose body was manufactured by A. Lange & Söhne. You can identify these clocks by the GUB company logo embossed in a cartouche-like, milled, semicircular recess. The location where the A. Lange & Söhne company logo was previously milled out.

It was only in 1956 after these clocks were completed and switched on, that GUB began producing their own clocks.
