Movements in Standard Electric Time Company Clocks
Detail of circa 1930
motor-wound, 6-day, double weight driven master clock movement with separate
winch mechanism mounted on common steel plate. One of the first electrically
wound master clocks built to run thru prolonged power outages without
the need for battery back-up. Bell included to indicate need for manual
resetting of secondary equipment following a power failure.
Specially constructed “salesman’s
sample” master clock movement. Made in response to competition from
E. Howard & Co. of Boston. Plates approximately twice the normal thickness
and certain gears even thicker than Howard’s. Lacks, however, the
fine-tooth train characteristic of the Howard master clock movement; tooth
counts same as regular production. This movement was shown as a sample
of what Standard was capable of making and not necessarily what the customer
would be getting unless an additional amount was paid. Few chose this
option and as a result, production probably did not exceed 100 units.
Later, a salesman’s demonstrator for the AR3 system was built using
Standard's regular master clock movement.

master clock movement; kick-off spring removed to reveal difference in
winding lever construction.
Master clock movement designed by Herbert H. Hammond
for the Dey Time Register Co. of Endicott, NY. Embodies all “Standard”
design features, copied following the expiration of key patents in the
early 1900’s. Hammond had previously worked for Standard!
Early 1920's master clock movement by
Electric Clock Co., badly in need of cleaning.
This circa 1950 motor-wound spring-driven master
clock movement was made for the Simplex Time Recorder Co. of Gardner,
MA. It is identical to the equivalent "Standard" master clock
movement except for certain parts of the automatic reset portion.
Later version of 6 or 8-day 2-weight master.
Factory method of mounting master movement in
grandfather cases of normal depth without rigid back board.
Movement and relays of a master clock capable of
running up to 800 secondary clocks without additional equipment other
than that supplying electric power. Heavy duty wiring throughout. The
master relay above the movement powers the coils of the 8 other relays,
each of which in turn supplies current to a corresponding group of secondary
clock circuits represented by one of 8 pilot clocks below. Customarily,
each circuit group would have its own power supply, the failure of which
would be indicated here by a stopped pilot clock. The cast iron relay
covers are rarely found in a master clock case; more often they are used
to protect relays on an electrical panel located elsewhere.
No. 2 secondary clock movement, straight impulse
(non-resetting), circa 1930's. Used mostly in clocks having dials 18 or
24 inches in diameter, and with longer handshaft, for marble dials in
this size range.

Pacific Electric Clock Co., San Francisco, Cal.

Jeffrey R. Wood, creator of the Standard Electric Time Co. (SETCO) pages of clockhistory.com, passed away in August of 2018. I will maintain the SETCO web pages in honor of Jeff, but will not be making any additions or changes, or answering any questions. It is hard to express how much I miss Jeff, his friendship, and his wonderful contributions to Standard Electric and Westclox research.
