I have a mechanical wall clock in storage which shows the day of the week as well as the date --- it was made in Japan --- it's in storage 'cause it was over-tightened and the main spring broken, and rather than being repaired, it was just re-fastened, so now it runs fast and gains a couple of minutes each month (the chime is also rather loud for a 1,200 sq. ft. home).
