PLEA for HELP:
We are always
searching for
copies of original
instruction sheets
and booklets for ANY
old clock to add to
these pages. If you
have one lying at
the back of a drawer,
gathering dust, could
we ask that you
consider letting us
scan it to include
on our site?

400 Day Instruction Sheet

This Instruction sheet was part of the original packaging when purchasing a Kundo, (Kieninger & Obergfell, Germany), 400-day clock during the late 1940's to mid/late-1950's.
It describes how to lock, and unlock, the pendulum when transporting; and also how to start, set and regulate the clock.

NOTE: The Schatz instructions appearing elsewhere on this site, even went so far as to advise upon how to replace the suspension spring.
Obviously, we do NOT recommend users try this at home!
The suspension spring and crutch setting of these clocks is the most critical of elements.
We suggest that ... IF you want your clock ever to work again afterwards; that you should not be tempted to 'have a go'.
In short ... don't!

CAUTION: To wind this (and all other 400-day style) clocks you should exercise caution.
The mainsprings used in these clocks are very strong.
Wind the clock by turning the key for no more than 1/2 a turn at a time, slowly but firmly releasing the key after each half-turn.
Never let let it snap back suddenly. To do so will run the risk of injury to yourself (due to the key hitting your fingers with force) and the clock (by potentially breaking the movement)
