Mechanical Ship's Clocks
Choosing a mechanical ship's clock
Selecting the right mechanical instrument requires matching the size, finish, and dial style to your interior space. Mechanical ship's clocks rely on precision internal craftsmanship, featuring an 8-day mechanical movement with 11 jewels that requires periodic winding with a key. Unlike quartz alternatives, these traditional mechanisms produce the authentic maritime chime, striking watch bells every half hour to mark sea watches on board.
When deciding on proportions, consider the diameter of the casing and dial visibility. Smaller cabins or compact offices benefit from the 155 mm case size, such as the Schatz 1881 Midi Mechanical Ship's Bell Clock Roman Polished Brass - 155 mm or its counterpart, the Schatz 1881 Midi Mechanical Ship's Bell Clock Roman Chrome-Plated Brass - ø155 mm. For larger saloons, vessel bulkheads, or spacious living rooms, the 180 mm series offers commanding presence and clear legibility at a distance.
Material and dial design also shape the aesthetic on board or at home:
- Polished Brass: Warm and traditional, ideal for classic wooden interiors, exemplified by the Schatz 1881 Royal 180 Mechanical Bell Clock Roman Brass.
- Matt Brass: Understated and refined, perfect if you prefer a subtle sheen, such as the Schatz 1881 Royal 180 Mechanical Bell Clock Arabic Matt Brass.
- Chrome-Plated Brass: Modern and bright, matching stainless steel fittings, seen in the Schatz 1881 Royal 180 Mechanical Bell Clock Arabic Chrome Brass.
- Dial Options: Choose Roman numerals for classical heritage or Arabic numerals for rapid, clear readability.

Care, delivery and warranty
To maintain your mechanical clock, wind the movement carefully once a week using the provided key, taking care not to over-wind the mainspring. Clean brass or chrome casings with a soft, dry microfibre cloth to prevent tarnish, avoiding abrasive polishes on lacquered surfaces. Ensure secure mounting to a sturdy bulkhead or wall to absorb vibration.

Frequently asked questions about Mechanical Ship's Clocks
How do I choose between the Midi and Royal mechanical ship's clock sizes?
Choose based on your available wall space and viewing distance. The Midi series, measuring 155 mm, is ideal for smaller vessel saloons, compact cabins, or home studies. The larger Royal series, at 180 mm, provides enhanced dial legibility across spacious rooms or larger bulkheads.
How should I securely mount a mechanical ship's clock on board a boat?
Mount the instrument securely to a vertical, flat wooden bulkhead or structural wall using suitable screws through its base plate. Ensure the location is free from extreme vibrations and moisture to maintain accurate mechanical timekeeping while underway.
How often do I need to wind and maintain a key-wound ship's clock?
Wind your clock once every seven days using the included key, turning gently until you feel firm resistance without forcing the spring. Wipe the casing occasionally with a dry microfibre cloth to maintain its shine, avoiding liquid chemical polishes on lacquered brass.
What are the shipping times, return policies, and warranty conditions for mechanical clocks?
In-stock orders placed before 12:30 on working days ship the same day via insured PostNL or DHL delivery. You benefit from free shipping in the Netherlands over € 75, a 14-day return right, and full manufacturer warranty support managed directly by our store.
How does the mechanical ship's bell movement chime the traditional sea watches?
The internal 11-jewel movement strikes traditional half-hour bell sequences marking four-hour watch periods on board. At the end of a four-hour watch, eight bells strike, signaling the crew shift change, creating an authentic nautical atmosphere in your room.
