If you do not wear the same automatic watch everyday, especially
the one with a screw down crown, a watch winder is a wonderful
tool for keeping your watch running.
Unfortunately, a watch winder is very expensive, a single
watch watch winder can cost you no less than US$ 30, a twin
watch watch winder cost you no less than US$40.
Although most manufacturers of the watch winders claim that
their products are professional, high quality, special designed
for the automatic watch, there is no lab test report on their
web sites or the Internet.
After making our own DIY Automatic Watch Winder, we can confirm
that there are really something a high end watch winder costs
us a lot:
- A good motor, it should be quiet and robust because a
watch winder may be running whole night, whole week, whole
year long although there are rest time for the watches and
the watch winder.
- A good motor, it should be small; therefore the motor
can be placed far from the watches in a small space. This
is critical because the motor is the main source of magnetism
which harms your watches.
- Magnetic Shield, the best way to protect your watches
from magnetism is wrapping your watches by the magnetic
shielding materials; however, these materials are not cheap,
so many manufacturers only use the "soft iron"
to confine the motors. Therefore, ask for "opening
/ disassembling" the case of the watch winder before
buying an expensive watch winder.
On the other hand, we confirmed that a watch winder can be
made at home with zero magnetism !

In our DIY Watch Winder Project, we try to use as little
money as possible, we would like to change the "rubbish"
to the useful watch winder.
Our target is to make a watch winder which is zero
magnetism inside the watch cage and can really wind
a automatic watch. After searching and thinking for
about 1 week, we decided to use the CD-R container to
construct the watch winder.
One CD-R container is for holding the watches, another
one is the motor room.
We cut the lid of one of the CD-R containers as the
photo shows.

An axle is needed, the diameter depends on the size
of the universal joint mentioned later.
When we chose the material as the axle, we tested it
with the compass.
If the compass rotates when you put the
material near the compass, the material is magnetized
- Do not use.
