Our Neptune range instruments have chunky cast brass casings, 5" in diameter and either lacquered or chrome plated, with bevelled glass fronts. They can either be screwed to a wall or bulkhead or mounted on a choice of mahogany or black-stained hardwood plinths for desktop use. Clocks are quartz movement, requiring 1xAA battery. Barometers have aneroid movements and show pressure in inches and millibars. Single display plinths are 6" wide, double display plinths are 12" wide, and overall height is 7"
Brass - an alloy of copper and zinc - is easy to work with, can be polished to a gleaming shine, and it has a high degree of corrosion resistance, making it the traditional choice of metal for use in harsh marine environments.
