Non-invasive testing apparatus for submersible timepieces

Non-invasive, portable, modular testing apparatus for non-invasively testing timepieces for fluid integrity without damaging or dismantling the timepiece and without interrupting the timekeeping function or operation thereof, comprising:

• a transparent tubular container member capable of providing a high pressure, fluid sealed environment for said timepiece, said container member being open at one end and provided with an enlarged, integral rim portion,
• a plurality of equidistantly spaced apertures disposed around said rim portion,
• the opposite integral end of said tubular container member including an enlarged integral rim portion equal in diameter to the rim portion of said open end providing a rigid, non rockable base for said container, a circular, rigid, transparent closure member for said container having equidistantly spaced apertures alignable with the apertures in the rim portion of said open end,
• attachment means receivable in said apertures, for securing said closure member to said tubular container member,
• means interposed between said closure member and said tubular container member for sealing said container member from the ambient atmosphere, and
• pressure applicator means integral with said tubular container member, including means for mounting and dismounting pressure producing means so as to automatically pressurize the internal volume of said tubular container member.
