\-Casio oceanus s100b. now this one is tricky and might not sell. ill be fully transparent i just bought this and i thought it would be a good idea to do a hydro mod on it. i was HORRIBLY mistaken. i took the watch apart and got it working again as it still receives the atomic time sync every night but only in the CHICAGO time zone. the crown is broken and you can not move the time zone unless you take the back plate off and use something very fine and pointed to minuplate the internals to get the seconds had to move. the case and bracelet and sapphire are free of marks and i understand if no one wants it. ill just keep it as a work watch. 100$ shipped
