Cal. 7K52A
CAUTION
The SEIKO SCUBA Cal. 7K52A is intended for use in diving, an inherently hazardous
form of recreation. Therefore, it is absolutely essential that you strictly observe all
instructions for the repairing and checking of the SEIKO SCUBA watch described in
this guide.
Take the greatest possible care when repairing and checking the depth measurement
function as well as the water resistant quality of this watch, because the depth meas-
urement serves as a guideline when the user is making a dive.
In addition, you must fully understand the following:
•
This watch is for use in recreational scuba diving (no-decompression diving), and
is not for decompression diving, saturation diving or diving at altitudes.
•
It is for use in water having a temperature range of 0
°
C to 40
°
C.
•
It can measure the depth of sea water correctly, whose specific gravity is 1.025,
but not that of fresh water.
It is recommended that you explain to users the specifications of the watch, limits of
use and cautions on improper use as required. In doing so, refer to the “CAUTION”
included at the beginning of the instruction booklet of the watch.
