This Plastimo ship's clock with radio silence is designed in the familiar porthole model and combines classic shipbuilding logic with practical daily use. The casing is made of solid brass and is available in two finishes: warm brass or matte chrome-plated brass. Both versions have the same solid dimensions with a 120 mm casing, an 80 mm dial, and an approximate height of 50 mm, keeping the clock compact yet clearly visible on a wall, bulkhead, or dashboard.

What makes this model special are the four silent zones on the dial. These refer to the traditional periods of radio silence, intended to keep emergency calls more audible. This gives the clock not only a functional nautical detail but also more character than a standard quartz ship's clock. The front features bevelled glass and can be opened from the front. This makes maintenance, battery replacement, and time correction noticeably easier, especially when permanently mounted on board or in interior projects with a maritime signature.
