In 1966, Seiko introduced their most expensive addition to their already diverse line watch line, the Bell-Matic - like this just serviced 27-jewel 1968 example here - a more expensive than Seiko’s previous models due to a newly-implemented complication – the novel and unique added mechanical alarm. 

The Seiko Bell-Matic was produced from late 1966 to 1978. They were made using "4006" automatic movements with 17, 21 or 27 jewels and while most featured the day and date there were a few models that featured the date only.  These were identified as a "4005" movement and were only manufactured before 1970.

 

The most outstanding feature on these watches is the mechanical watches?  The alarm of course!  The alarm is wound and set using the crown and engaged using the alarm button. In addition to these functions the crown also serves to set the time and the alarm button can quick-set the date.

INSTRUCTIONS: To use the alarm, pull the crown out to the first position and rotate counter clockwise until the red marker is pointing towards the time you want it to go off.  Press the crown in, manually wind, then pull the button at the 2 o’clock position.  When the hour hand points to the time, a little bell rings, much like an old fashioned alarm clock.  Separately, to set the date, depress the same 2 o’clock button in (much like on the Seiko 6139 helmet) repeatedly until the correct date is reached.  Finally, to set the day, pull the crown to the second position and turn the hands to the 1 o’clock position; reverse hands counter clockwise to 9:30 pm and then turn clockwise to 1 am once again – the day will advance, repeat until desired day of the week is reached.

 

This Bell Matic comes with a leather strap, NATO strap, springbar tool, and Pelican travel case.
