Plastimo matt chrome clock set 4 inch - clock, barometer, thermo-hygrometer
This Plastimo 130mm (4 inch) set brings together a clock, barometer, and thermo-hygrometer in matt chrome, each with a bevelled glass edge and a front opening for easy access. You can choose the clock in the standard version or with radio silence zones, which are sectors where marine radio traffic takes precedence. The barometer uses a highly sensitive aneroid mechanism in a solid brass housing for accurate atmospheric pressure readings. The thermo-hygrometer displays temperature and humidity, providing a complete picture of the indoor climate. All three instruments measure 130mm on the outside and 88 mm (3.46 inches) on the dial.
Plastimo matt chrome clock set 3 inch - Clock, Barometer, Thermo-Hygrometer
This Plastimo set combines a clock, barometer, and thermo/hygrometer in matte chrome-plated brass, all three 120mm (3 inches) in diameter. The clock can be chosen with four radio silence zones, the periods when marine radio traffic takes precedence, or without zones for a clearer dial. The barometer reads atmospheric pressure on two scales, mbar and mmHg, through a porthole design with bevelled glass. The hygro-thermometer displays humidity and temperature, providing a complete picture of the indoor climate on board or at home.
This Plastimo set of 140mm (4.5 inch) brings together three reliable instruments in brass: a clock, a barometer, and a thermo-hygrometer, all three with a Roman dial and a bevelled glass edge. Choose the clock in the standard version or as a tide clock, which indicates not only the time but also the ebb and flow. The barometer measures air pressure with an aneroid mechanism and a full metal chain, measuring range 960–1060 hPa, accuracy ±3 hPa between 990–1030 hPa. The thermo-hygrometer, in a brass housing with a porthole design, displays temperature and humidity for a complete picture of the indoor climate. And a porthole opening is very convenient if you want to change the settings of your instrument. Easy to hang with a screw opening on the front. The dial measures 100mm, the outer dimension of the housing 140mm, for each instrument.
This 120mm Plastimo clock set brings together three instruments in solid brass: a clock, a barometer, and a thermo/hygrometer. The clock is available with a Roman numeral dial, with silent zones in blue and red for on-board radio use, or with a built-in alarm function. Convenient for those who sail in shifts and always sleep through their alarm. The barometer reads the atmospheric pressure, the thermo/hygrometer displays temperature and humidity, together providing a complete picture of the indoor climate on board or at home. All three instruments measure 120mm (3 inches) and are finished in brass, with a Roman numeral dial as a consistent style throughout the set.
A barograph records the story of the weather, but only with the correct chart paper will this remain visible. This set of 100 sheets is specifically suitable for the Plastimo barograph and provides almost two years of continuous recording with weekly changes.
Each line records the course of the air pressure: from calm changes to the arrival of a depression. The paper is therefore an essential part of the instrument. Without a sheet, no recording; without a recording, no valuable weather archive.
Replacement fiber pen for the Plastimo barograph. A barograph is only as good as its pen: if the line becomes faint or jagged, it is not a defect but a worn tip, and this is the solution. This fiber scriber is suitable for the traditional Plastimo barograph.
The Plastimo barograph does what no barometer can: it remembers. With an accurate aneroid mechanism, a stylus continuously records the atmospheric pressure on a rotating paper drum. This allows you to see not only the current atmospheric pressure, but also how the weather has developed over the past few days. A classic maritime instrument that has been used for generations on board, at home and in weather stations.
Several brass measuring instruments together on a 350 mm teak holder: the complete weather picture as one wall object. Teak and brass are shipbuilding's oldest friends - here they hang together on your wall.
The large pair in one order: the 220mm ship's clock with Roman numerals and the matching aneroid barometer, both in brass. For a wall that demands a statement, on the bridge, in the office, above the fireplace, or in the hall of a harbour pavilion. But this is also a nautical statement on board. Due to its size, the porthole has two openings, which also gives it its extra charm.
The barometer in the large 220 mm format: aneroid measurement, brass housing, a scale that can be read from a distance.

A good captain not only looks ahead but also at the air pressure. This compact Plastimo barometer combines accurate measurements with a stylish maritime look. The matte chrome finish gives the instrument a modern and calm appearance, while the classic design fits perfectly in a wheelhouse, cabin, office, or interior with a nautical atmosphere.
The barometer works with a highly sensitive aneroid mechanism, measuring changes in atmospheric pressure without using liquids. Ideal for anyone who wants to detect weather changes early, both on the water and at home. Thanks to the clear white dial with black markings, the air pressure is easy to read.
The sturdy chrome-plated brass casing feels solid and is designed for long-term use in marine conditions. Compact in size, yet strikingly stylish on a wall, dashboard, or in a wheelhouse. A beautiful nautical instrument for enthusiasts of water sports, classic ship instruments, and timeless maritime design.
This Plastimo ship's clock with radio silence is designed in the familiar porthole model and combines classic shipbuilding logic with practical everyday 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 120mm casing, an 80mm dial, and an approximate build height of 50mm, keeping the clock compact yet clearly present on a wall, bulkhead, or dashboard. It displays time in a 24-hour format with large numerals from 0 to 12 and smaller Arabic numerals from 13 to 24. The dial features the traditional red and green radio silence zones, a classic maritime detail that refers to historical emergency and safety communication at sea.
What makes this model special are the four silent zones on the dial. These refer to the traditional periods of radio silence, intended to make 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 changes, and time correction noticeably easier, especially when permanently mounted on board or in interior projects with a maritime signature.
The Plastimo 3-inch is designed according to the trusted porthole principle, with a substantial brass casing and a variant in a matte chrome finish or glossy brass color. This makes this ship's clock particularly suitable for installation in a wheelhouse, cabin, dashboard, or any maritime interior where lighting varies. The 80mm white dial keeps the time display clear and calm, while the quartz mechanism requires little maintenance and runs reliably.
What strongly distinguishes this model within the range is the front opening. For a battery change or resetting the time, you don't first have to unscrew the clock. This is practical on board, but also pleasant at home, in the office, or in a hospitality environment. With its construction height of approximately 50 mm and base diameter of 120 mm, this clock has visible weight and presence. It is a classic Plastimo model that has been appreciated for years for its solid construction, recognizable shape, and durable usability.
Frequently asked questions
That mainly depends on the available space and the aesthetic you are looking for. The 3-inch series is compact and subtle, while the 4 and 4.5-inch series have a bit more presence. With its large size, the 6-inch series is designed to be seen and is a real eye-catcher on the wall.
No. Of course, they are designed with water sports in mind, but it is precisely the classic nautical design that makes them exceptionally suitable for an office, restaurant, holiday home or living room. Especially the heavier brass versions are beautiful interior pieces
A barometer measures air pressure. A weather station combines multiple meteorological functions in one instrument. A barograph goes a step further and records air pressure changes over a longer period. Which one is best suited thus mainly depends on what you want to do with it and how you intend to use the instrument.
Over the years, Plastimo has built a strong reputation in water sports. Their instruments are robust, easy to read, and have a classic nautical design. Furthermore, Plastimo offers an attractive price for a truly marine instrument.
That is precisely one of the most appealing aspects of the collection. For example, by combining a ship's clock with a barometer, or by placing multiple instruments from the same series next to each other, a beautiful and cohesive whole is created. Pay particular attention to the same series and diameter if you want to create a truly uniform set.
