NOTE: If your watch stops, it must be wound by turning the crown clockwise approximately 25 full
turns. Although the watch is automatic, the mainspring may not have enough reserve to keep it running
accurately. Once wound, the normal movement of wearing the watch will provide enough power to
keep accurate time.

minute hands*
Date changes each
time hour hand passes
midnight (24:00 hours)
*Note - For precise setting of time, it is recommended to adjust
the minute hand past the required time and turn backwards to
the desired minute.
Setting crown in position Stops the Second Hand to allow synchronizing with a time signal.
There are many accurate sources for this time signal including shortwave radio frequencies that
continuously announce GMT (UTC) and the internet.
Setting Date and GMT
3.
GMT (Greenwich Median Time) is an international time standard originally established to facilitate oceanic navigation
and is based on the time in Greenwich, England from which the remaining 23 global time zones are derived.
GMT is 5 hours ahead of Eastern Standard Time (EST) and 4 hours ahead of Eastern Daylight Time (EDT) during
Daylight Savings Time. So if the time is 0900 GMT, it is 4:00AM in New York City and 1:00AM in Los Angeles during
Eastern Standard Time (EST), but during Eastern Daylight Time (EDT) it is 5:00AM in New York City and 2:00AM in
Los Angeles. GMT is also referred to as Coordinated Universal Time (UTC) or Zulu Time (Z).

- Important Note When setting Date and GMT, the minute and hour hands must not be positioned between
8PM (20:00) and 3AM (03:00). During this time the date mechanism is engaged and
adjusting it may cause damage to the gear.
Setting Second Time Zone
4.
The rotating bidirectional bezel allows for the setting of a second time zone in
addition to the GMT 24 hour markers on the dial. The GMT hour hand indicates
the second time zone on the bezel in 24 hour format also. Minutes and seconds
are read on the dial’s minute and second hands.

At 32°F (0°C), sound travels at 332m or 363yds /

NOTE:

Alternately, you can divide the measured time at
68°F by 4.68 to get miles (10s / 4.68 = 2.14miles),
or 2.66 for thousand yard distance, or by 2.91 for
kilometers.

For example the measured lightning to thunder
time at 68°F is 10 seconds. 10 x 344m or
376yds / 1,129ft would produce 3,440m or
3,760yds / 11,290ft. (2.14miles)
I 6 I 8

To estimate the distance to an event (such as an
explosion, muzzle flash, lightning, etc.), measure
the time from the visual flash to the sound and
multiply the seconds by the per second speed.

1 mile (1,760 yards / 5,280 feet) in 4.68 seconds
2.66 seconds
1,000 yards in

1 kilometer in
Example: Sea level temp is 68°F and
lightning to thunder measured time is 18
seconds. Distance of lightning strike point
is:
18s x 1,129ft = 20,322ft
18s x 376yds = 6,768yds
18s x 344m = 6,192meters
OR:
18s / 4.68s
= 3.85 miles
18s / 2.66s
= 6.77 thousand yards
18s / 2.91s
= 6.18 kilometers
