TigerShark Classic Dive Watches
Why a classic dive watch design? Because they work... and look great,
above or underneath the water. Let's look at the elements of a good dive
watch design:
High contrast
easy-to-read display Water resistance Corrosion resistance Durability and
dependability
The same elements make for a wonderful watch on dry
land as well! The TigerShark Classic Dive Watch is equipped with a face that's easy to read at a glance, a magnified date
display and a 90 -click uni-directional countdown bezel. With it's screw-down case-back and double O-ring
threaded crown, the TigerShark Classic Dive Watch offers water resistance to 300 meters. The watch case and band
are made of high quality stainless steel. The movement is a fine Swiss ETA 2824-2, 25 jewel self-winding
mechanical workhorse. We didn't stop there - the crystal is sapphire and the band has adjustable links
attached with screws (not push-pins) as well as solid end links and milled clasp pivots. Of course there is a dive-suit
extension on the band for added functionality.


The TigerShark Classic Dive Watch is a rugged timepiece. It weighs 162
grams, or just under
six ounces. The watch is 39.5mm wide without the crown and 43mm wide with
the crown.
The lug width is 20mm and bracelet is 3.5mm thick. The watch case 12mm
thick.
The TigerShark Classic Dive Watch comes with a high quality stainless
steel bracelet
the can accommodate a wrist circumference of up to 20.5cm or 8 inches.


The
"Heart" of a TigerShark Watch
You're looking at one of the key elements that make mechanical watches
so appealing - the machinery of timekeeping. No battery-powered
quartz-regulated stuff here, just mechanical ingenuity, expert design, and top quality
manufacturing. All watch movements depend on
dividing increments of time into small, constant periods determined by the
operating frequency of the watch’s vibrating system. The “time divider”
must receive power from a “power source.” This power must be transmitted
from the source to the divider, so there must be a system for “power
transmission.” Only sundials work on a system different than described above,
and they just don’t wear well on the wrist.

Automatic Mechanical Movement
In a TigerShark watch, a rotor is used to wind the mainspring; as the
spring unwinds, the toothed rim of its casing sets the wheels of the
power transmission (train) in motion, which acts on the
hands to show the time. In order to create a time divider, the balance wheel
rotates a half-turn in one direction before being pulled up by the hairspring at
its center, turning it in the opposite direction. This oscillation breaks the
action down into equal parts. These half-turns (or oscillations) are
called vibrations and are known as the “beat” of a watch. A normal movement
beats at 18,000 vibrations per hour. The rotor that winds the
mainspring is activated by normal movement while wearing the TigerShark
watch.
The picture to the left shows the internal workings of a TigerShark
watch. The movement is a Swiss ETA, 2824-2 with 25-jewels. This fine Swiss
movement is a real workhorse and is used in a wide range of well-known
watch brands including Tudor by Rolex. The half-circular rotor can be
clearly seen in the top part of the image and the manufacturer's markings
are shown in the lower part of the image.
The ETA 2824-2 movement "hacks". That is to say that the seconds hand
stops running when the crown is pulled out. It will start up again when
the crown is pushed in. This feature facilitates synchronizing the watch
with another watch or time display. The ETA 2824-2 can also be manually
wound.
Getting to Know Your TigerShark Watch
Starting Out
TigerShark Classic Dive Watches come with a high quality stainless
steel band that will likely need to be sized in order to correctly fit
your wrist. There are several removable links near the clasp. These links
are held by double threaded retainers. While these can be taken out by
using two very small screwdrivers, it is recommended that you have your
dealer or a qualified watch service technician perform this task. There
are further small adjustment points on the side of the clasp that the dive
extension attaches to.
As it is mechanically powered, your TigerShark watch may not be running
when you first receive it. The watch gets its power from the normal motion
of being worn. To "start" the movement carefully unscrew the crown,
when free of the threads the crown will turn with some mild resistance.
Turn the crown clockwise for 20 full rotations, this will give some power
to the mainspring. Gently pull the crown out a little more until you feel
the first "click" or detent. In this position, the date can be set
by turning the crown clockwise. Set the watch to date before today. Now
pull the crown out a little further to the second (last) click or
detent. From this position you will notice that the second hand has
stopped and you can turn the crown to set the current time. Turning
"through" midnight will roll the date display over to the current date.
Now you can gently push the crown in and carefully thread it to the closed
position. The crown is threaded to help ensure water resistance. Please be
sure to loosen and tighten the crown carefully. A Word About Accuracy
TigerShark Classic Dive Watches utilize a Swiss automatic mechanical
movement. This type of movement is often preferred in situations when the
"risk" of a dead battery stopping a watch is a concern. There are 86,400
seconds in a day and a good mechanical movement can be accurate to plus or
minus 15 seconds per day (even better accuracy is sometimes possible).
That's 99.983% accurate. Having said that, a good quartz movement is going
to be more accurate than a mechanical movement - as long as the power
supply is there.
Caring For Your TigerShark Watch
TigerShark Classic Dive Watches are constructed of high quality
components designed to give you many years of service. The mechanical
movement will require routine cleaning, service and lubrication. This
should only be performed by skilled service technician or master
watchmaker. The frequency of service will depend on many circumstances
including the environment the watch is worn in. Typical service
requirements can vary from once per year under harsh conditions to as
infrequently as every five years.
