The handsome Weems and Plath Nautilus Clock is waterproof and so it can function extremely well in the punishing saltwater environment let alone if it is used to give a nautical flavour in a home or in an office.

The low-glare, satin black case is constructed of solid aluminium that is colour-anodised and sealed so that the finish will not peel, bubble or tarnish.

The glass crystal of the Weems and Plath Nautilus Clock sits in a double O-ring seat for protection from vibration, impact and thermal expansion. The anodised aluminium dial is laser engraved.

The durable moveable markers are made of UV-stabilized polycarbonate outside the crystal for marking time or pressure and all fasteners are stainless steel.

To calibrate the movement, twist the case 1/8th of a turn to remove the case and leave the back plate on the bulkhead or wall to which it has been attached. This feature is also convenient should you want to remove your clock for storage or anti-theft reasons.

The clock contains a precision quartz movement which is accurate to ±15 seconds a month and its waterproofing in water extends to a depth of 100 feet.
