33

Movement

The

Model

33

movement

is

a 13 ligne serf-winding movement with

day

and

date

features. The

Model

33 utilizes the same basic construction

as

the

Model

31

except

that

a

day

and

date

mechanism has been added. A plane-

tary

gear

winding

system located on the Front Frame provides a compact

method

of

obtaining

the necessary

gear

reduction between the self-winding

weight

and

the mainspring.

The reserve

power

of

the mainspring when the watch

is

worn

by

a

normally

active person

is

sufficient

to

run the watch

for

a full

day.

The

day

and

date

mechanism

is

similar

to

that

used

in

the

Model

27.

CAUTION:

Any

attempt

to
