BEFORE STARTING REPAIR WORK ON CAL. 5D88A
SEIKO Kinetic Direct Drive Cal. 5D88 is an embodiment of the SEIKO's 'emotional technology'.
The watch features new functions but the knowledge of repairing the existing KINETIC series
will be helpful.
To repair the Cal. 5D88, therefore, you are requested to have the full knowledge of its functions
and strictly observe the repairing and checking instructions provided in this guide so that the
watch will be correctly repaired.
FEATURES
The Cal. 5D88 is a KINETIC watch equipped with two winding functions and two indicator
functions.
l Two winding functions
As in all existing Kinetic calibers, the wearer automatically generates the electrical
energy by her/his wrist movement. With Kinetic Direct Drive, however, the wearer can
also generate energy by winding the crown.
l Two indicator functions
Kinetic Direct Drive shows not only the power held in reserve but also the level of power
generation when the wearer hand-winds the crown. The wearer can see and feel, in real
time, the direct transfer of power from his or her winding of the crown to the reserve.
