AUTONAUTIC clocks, stopwatches and weather instruments combine traditional marine design and the elegance of classic nautical clocks and weather instruments. The brass binnacles have been "Flash" plated with 18-carat gold using an advanced brass plating technology that makes our instrument binnacles maintenance-free. The binnacles are highly resistant to salt spray and will not rust or darken in marine environments. The appearance of the brass will always remain the same, even if it is exposed to the marine environment for a long time.
