The stainless-steel case of the Zeppelin 84662 watch is nicely complimented by a leather band. A Japanese mechanical Miyota 8205 movement with automated winding is housed inside the casing. The glass case back allows one to see the watch's 21 bearing stones and 21, 600 semi-frequencies of ticking every hour. The function at 3 o'clock that indicates the date and day of the week is quite useful.
