Please see photos for condition and measurements of the watch.  In fantastic vintage condition. Watch is nice with time, day and date functions working well. Please note this is a vintage watch so I cannot guarantee accuracy. 

To set the date and day.. First use pull the crown to the 2nd position to adjust the time so the day function changes. Stop once it is set to the day before desired day.  Push crown in and pull to the 1st position and set the date to the date before the desired date. Then pull the crown to the 2nd position again and set time forward to the correct time, day and date.
