CAUTION
The SEIKO SCUBA DIVER’S Cal. 7K52 is intended for use in an
inherently hazardous form of recreation. Therefore, it is
absolutely essential that you observe strictly all instructions
for the use and maintenance of the watch set forth in this
booklet.
First of all, this watch is for use by adults only in recreational
(no-decompression) diving in water having a specific gravity
of 1.025 (sea water), having a temperature range of 0°C to 40°
C, and is not for decompression diving, saturation diving or
diving at altitudes (diving in a high mountain lake, etc.). Unless
you have undergone scuba training with a qualified instructor,
you can neither fully appreciate the concept of no-
decompression limits nor properly employ the watch.

DO NOT ATTEMPT TO DIVE USING THE WATCH UNLESS YOU
HAVE BEEN PROPERLY TRAINED IN SCUBA DIVING, POSSESS
THE REQUISITE EXPERIENCE AND SKILL TO DIVE SAFELY,
HAVE THOROUGHLY FAMILIARIZED YOURSELF WITH THE
OPERATION AND MAINTENANCE OF THE WATCH, AND HAVE
TESTED ALL WATCH FUNCTIONS PRIOR TO EACH DIVE.
In addition, sharp fluctuations in atmospheric pressure and
aquatic environments may affect the performance of the watch.
When making a dive, use other diving instruments such as dive
computers together with this watch for safety’s sake.
Finally, all of the diving measurements made by the watch and
warning functions of the watch, outlined herein, are to serve as
general guidelines only, and individual reactions will differ
from person to person.
