just received gmt ll batman from andiot watch. watch looks great but was told by andiot not to use for swimming. took to local high end watch repair shop for pressure testing. good for everday use but not swimming. they will open watch and check, replace gaskets, approx. $100. watch is supposed from clean factory with dd3285 movement. question why factories won't go a step further and install $1 worth of gaskets for waterproofing
