A marine instrument, such as a clock, barometer, or thermometer, has a face having indicia associated with the face, an instrument movement, and at least one hand having a direct or indirect connection to the movement and positioned to move with respect to the face, or a display connected to an electronic movement. The components are encased within a casing that is water tight to at least 12 inches (e.g. about 30 feet) of water. A vent, such as a porous plastic plug, allows the passage of air in and out of a substantially water-tight volume containing the movement, but precludes water passage up to the rated pressure. The casing may be formed by first and second aluminum portions which have flange and groove (bayonet) readily releasable connections, and an O-ring seal, and a third aluminum portion opposite the first portion and making a seal, including with a lens, and at least one O-ring, with the second portion and releasable fasteners holding the third portion to the second portion with the lens covering the face.
