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.
