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.

What is claimed is: 1. A marine instrument comprising: a face having indicia associated therewith; an electrical, mechanical, electronic, or electro-mechanical instrument movement; at least one hand operatively connected to said movement and positioned to move with respect to said face; a casing water tight to at least about 12 inches of water, said movement, face and at least one hand disposed within said water-tight casing; and a first portion of said casing which facilitates fixing of said casing directly on a surface, and a second portion of said casing which is readily movably mounted with respect to said first portion to allow access to said movement when said first and second portions are in a first position, and precluding access to said movement when said first and second portions are in a second position, wherein a substantially water-tight volume is defined between said first and second portions when in said second position, and further comprising a vent substantially continuously allowing passage of air in and out of said volume but precluding passage of water into said volume under a pressure of at least 12 inches of water. 2. A marine instrument as recited in claim 1 wherein said vent comprises at least one plug of porous plastic. 3. An instrument as recited in claim 1 wherein said movement comprises a battery powered movement, and wherein said face comprises a clock face having clock indicia thereon, and wherein at least two hands are operatively connected to said movement and positioned to move with respect to said face. 4. An instrument as recited in claim 1 wherein said movement comprises a barometer movement, and wherein said face comprises a barometer face having barometer indicia thereon; and further comprising a manually movable indicator cooperable with said barometer face. 5. An instrument as recited in claim 1 further comprising an inclination indicator mounted in said casing adjacent said face and visible from exterior of said casing when viewing said face. 6. A marine instrument comprising: a face having indicia associated therewith; an electrical, mechanical, electronic, or electro-mechanical instrument movement; at least one hand operatively connected to said movement and positioned to move with respect to said face; a casing water tight to at least about 12 inches of water, said movement, face and at least one hand disposed within said water-tight casing; and a first portion of said casing which facilitates fixing of said casing directly on a surface, and a second portion of said casing which is readily movably mounted with respect to said first portion to allow access to said movement when said first and second portions are in a first position, and precluding access to said movement when said first and second portions are in a second position, wherein said first and second portions of said casing are movably mounted with respect to each other by a plurality of flange and groove connections, and further comprising at least one seal mounted on at least one of said first and second portions for providing a substantially water-tight seal between said first and second portion in said second position. 7. An instrument as recited in claim 6 wherein said at least one seal comprises at least one O-ring radially outward of said flange and groove connections. 8. A marine instrument comprising: a face having indicia associated therewith; an electrical, mechanical, electronic, or electro-mechanical instrument movement; at least one hand operatively connected to said movement and positioned to move with respect to said face; a casing water tight to at least about 12 inches of water, said movement, face and at least one hand disposed within said water-tight casing; and a first portion of said casing which facilitates fixing of said casing directly on a surface, and a second portion of said casing which is readily movably mounted with respect to said first portion to allow access to said movement when said first and second portions are in a first position, and precluding access to said movement when said first and second portions are in a second position, wherein said casing further comprises a third portion on the opposite side of said second portion from said first portion, and a lens, said lens covering said face and being held in substantially water-tight relationship with at least one of said face and said second portion by said third portion; and wherein said third portion is mounted by a plurality of releasable mechanical fasteners to said second portion. 9. An instrument as recited in claim 8 wherein said first, second, and third casing portions are of aluminum, and wherein said lens is of transparent glass or plastic. 10. A marine instrument comprising: a face having a display; an electrical, mechanical, electronic, or electro-mechanical instrument movement, operatively connected to said display; a casing water tight to at least about 12 inches of water, said movement and face disposed within a substantially water-tight volume of said water-tight casing; and a vent substantially continuously allowing passage of air in and out of said volume but precluding passage of moisture into said volume under a pressure of at least 12 inches of water. 11. An instrument as recited in claim 10 wherein said vent comprises at least one plug of porous plastic. 12. An instrument as recited in claim 10 wherein said casing is water-tight, and said vent precludes passage of water into said volume, to at least a pressure of about 30 feet of water. 13. An instrument as recited in claim 10 wherein said casing comprises first, second, and third portions, said portions sealed to each other by O-ring seals, with said second portion between said first and third portions, and wherein said second portion is substantially tubular. 14. An instrument as recited in claim 13 wherein said first and second portions are readily releasably held together by a plurality of flanges and grooves, and wherein said second and third portions are held together by releasable mechanical fasteners. 15. A marine instrument comprising: a face having a display; an electrical, mechanical, electronic, or electro-mechanical instrument movement; a casing water tight to at least about 12 inches of water and comprising a body portion, a cover portion, and a lens portion; said casing body portion containing therein or mounting thereon said movement and face; and said casing body portion covered by said lens portion and said cover portion, and said cover portion holding said lens portion in contact with said body portion making a substantially water-tight seal with said body portion, and said face and display visible from outside said casing through said lens, wherein said substantially water-tight seal between said body portion and said cover and lens portions is provided by at least one O-ring seal. 16. An instrument as recited in claim 15 wherein said movement comprises a barometer movement, and wherein at least one of said face and said display comprises barometer indicia. 17. An instrument as recited in claim 15 further comprising an inclination indicator mounted in said casing adjacent said face and visible from exterior of said casing when viewing said face. 18. An instrument as recited in claim 15 wherein said movement comprises a battery powered clock movement, and wherein said face comprises a clock face having clock indicia thereon, and further comprising at least two hands movable with respect to said face clock indicia.
