Important!
Auto Light may not operate properly
●
when the watch is at a horizontal angle
of 15 degrees or greater from

Electro-static charge or magnetism

can interfere with proper auto light
operation. If this happens, try lowering
your arm and then angle it towards
your face again.
When moving the watch you may note

a slight rattling sound. This is due to
operation of the auto light switch,
which determines the current
orientation of the watch. It does not
indicate malfunction.
