6MR-11MR
The MR synchronous versions keep time using the 60Hz power line. The synchronized motor provides smooth continuous movement of the hands. A National Time transmission advances the clock at 10 times speed with a single motor. A remote manual switch can be used to adjust the clock. A master clock or clock controller can be used to automatically correct the time for power outages or daylight savings adjustments.

6MI-11MI
The MI minute impulse advances incrementally each minute utilizing a single direction motor. An MC3 Master Clock Controller is required for operation and provides automatic correction. The MI series will not drift when employed in countries that do not regulate power line frequency or installations that may have generator backup power. An MC3 Master Clock with the 4 circuit expansion switches allows user to remotely adjust up to 4 clocks independently during installation or repair.
