It says Henri Viatte Design and Chrono Quartz on it . The band is unbranded and the back says SMSA 2091 . I can't find any info on this watch anywhere . I almost passed it up at first glance because the case was really corroded and it looked like an inexpensive generic watch . The nice band was what made me look closer . The seller claimed that it had a Swiss module and that it did not work . I decided to take a chance on it and to my surprise it did indeed have a Swiss module . It also came to life after a little clean up . It has time ,date with day of the week and a chronograph . Seems to have been a nice watch in it's day . I did not think to get any inside shots when I had it opened .
