used in very good condition brand new battery this watch is about 20 years old ....it is made in Japan ....I cannot find a brand name on the watch ....the black watch band broke on a dive trip I took it on so I got a new watch band ....it is green ...it no longer comes with the black band ....it comes with the green band now.....the black part/body appears to be plastic .......it will come with the green watch band.
