Small Porthole Clock (Polished Chrome over Brass)

The Royal Mariner Porthole range of instruments are based on a traditional porthole design, with hinge and two dog screws for latching.

These instruments are manufactured from solid unlacquered brass, which has been over plated with a polished chrome finish.

Batteries can be easily replaced on these instruments as they are accessible by opening the front opening porthole mechanism.

Clocks are available as either a standard timepiece, or tide clocks, which have an additional hand to indicate lunar time.

Lunar time covers a period of 24 Hours and 50 minutes, which approximates the cycle of high and low tides.
