NAUTICA watches have been developed with the highest attention to quality, function and detail, as befits the NAUTICA tradition. Please read the following instructions carefully to fully understand all of the functions of your finely crafted timepiece.

WATER-RESISTANCE

If your watch is water-resistant, it will be indicated on the watch face or on the caseback.

  • 50 Meter Water-Resistant watch withstands water pressure to 86p.s.i.a. (equals immersion to 164 feet or 50 meters below sea level) and dust as long as crystal, crown and case remain intact.
  • 100 Meter Water-Resistant watch withstands water pressure to 160p.s.i.a. (equals immersion to 328 feet or 100 meters below sea level) and dust as long as crystal, crown and case remain intact.
  • 200 Meter Water-Resistant watch withstands water pressure to 320p.s.i.a. (equals immersion to 656 feet or 200 meters below sea level) and dust as long as crystal, crown and case remain intact.

NOTE: CROWN MUST BE SCREWED INTO THE CASE PROTRUSION TO ASSURE WATER RESISTANCE. WATCH IS NOT AN ISO 6425 CERTIFIED DIVE WATCH.

If your watch has "INDIGLO" on the dial, your watch is equipped with the INDIGLO Night-Light. To activate this feature, depress the crown or the pusher on the left side of the watch to illuminate the entire dial for easy reading during nighttime or low light conditions. Light will appear immediately.

Your NAUTICA watch featuring INDIGLO Night-Light contains a patented electroluminescent technology (U.S. Patent Number 4,527,96 and 4,775,964). The INDIGLO Night-Light illuminates the entire watch lens with a uniform bright light that offers superior readability in all low light and nighttime conditions. Simply press the appropriate button to activate.

WARNING: DO NOT PRESS THE BUTTON UNDER WATER AS THE WATCH WILL NOT RETAIN WATER RESISTANCE

INDIGLO is a registered trademark of Indiglo Corporation.

BATTERY

Please recycle or dispose of battery properly. Do not dispose of battery in the fire. Do not recharge battery. Keep loose batteries away from children.

SCREW-IN SETTING CROWN

Nautica BFD 105 Chrono - SCREW-IN SETTING CROWN - 1

text_image ATTENTION This is a screw down crown Do not pull Please read instruction booklet before operation

SCREW-IN SETTING CROWN STICKER

Some deep-depth water-resistant watches require the setting crown to be screwed in to ensure water-resistancy. If your Nautica watch has a transparent sticker at back of the case back (diagram above) please unscrew the crown before setting your watch, and the crown must be screwed in after setting the watch.

To screw in, push in the crown firmly against the thread protrusion and hold it in while turning the crown clockwise. Continue to screw in the crown light until it is tight.

ELAPSED TIME RING

If your watch is equipped with a rotating outer dial with numbers and indicators, this Elapsed Time Ring may be used to indicate the length of time remaining for an activity or the starting time of an activity.

TIME REMAINING - set the outer ring so that the triangle is pointing to the time the activity is to end.

STARTING TIME - set the triangle on the time the activity is to begin.

TACHYMETER

A tachymeter measures the speed at which the wearer has traveled over a measured distance, i.e., a measured mile on the highway. For example, start the chronograph when you pass the starting point and stop it when you pass the finish point. You can then read your speed in units per hour off the tachymeter scale.

BAND ADJUSTMENT

Nautica BFD 105 Chrono - BAND ADJUSTMENT - 1

To reassemble band to clasp, place spring bar in band and place end of spring bar into desired hole in clasp. Press opposite end of spring bar in and slide into clasp and position so tip snaps into corresponding hole.

TIDE CLOCK

Indicator hand always rotates clockwise, so tide is rising when hand is pointing left and falling when pointing right. The tide cycle takes place over one revolution of the dial in 12 hours 25 minutes and 14 seconds. High tide corresponds to the "12 o'clock" position and low tide corresponds to the opposite position, hence "6 o'clock".

Tides are influenced by moon and sun and shape of shoreline, so tide clock cannot precisely give times of high and low tides. Periodic adjustment may be necessary.

To set the Tide Function – Indicator Hand

  1. Pull crown to position "B".
  2. Press B (TIDE) push button to set the state of the local tide.
  3. Push crown to position "A".

THERMOMETER

When worn on wrist, thermometer reading is affected by body heat. For more accurate readings, remove watch and put in shade for at least several minutes. Watch can measure water temperature also, if submerged. Be sure to select temperature display before placing watch in water, as buttons should not be pressed when watch is underwater. Thermometer readings are taken every minute, and more frequently, if temperature is changing.

COMPASS CALIBRATION

The compass must be calibrated before use. Since a compass uses the earth's magnetic field, you must be aware of large metallic objects, such as vehicles or bridges, or objects that give off electromagnetic radiation, such as televisions or computers, which could affect the

magnetic field around the watch. Do not store the watch near any source of magnetism, such as a computer, appliance, or television, as the watch can take on a magnetic charge, yielding inaccurate headings. Typical accuracy of wrist-worn instruments is within +/- 10 degrees.

To calibrate the compass:

  1. Pull the crown to position "B" and wait for the indicator hands to stop moving.
  2. Keep the watch in horizontal position and dial facing upward.
  3. Press C (COMPASS) to begin. The indicator hand rotates two revolutions to remind you to rotate the watch. While level, SLOWLY rotate the watch two revolutions, taking at least 15 seconds per revolution.

  4. When done, press C (Compass), keeping the watch level. The indicator hand moves back and forth to acknowledge

Nautica BFD 105 Chrono - To calibrate the compass: - 1

the end of calibration and then moves to the current magnetic declination setting.

  1. If you do not wish to set the magnetic declination, push the crown in. Otherwise, to have watch automatically compensate for the

declination angle, turn the compass ring until north is at 12 o'clock. 6. Press A or B pusher to move the indicator hand west (-) or east (+), respectively, to point to your location's declination angle using the declination scale. Hold a button to move the hand quickly.

Nautica BFD 105 Chrono - To calibrate the compass: - 2
MAGNETIC DECLINATION SET TO -14° (14°W)

  1. Push the crown to position "A" when done.

COMPASS OPERATION

Normally, the compass is inactive. While holding the watch level, press C (COMPASS) to activate the compass. The indicator hand moves to point north. If the watch is turned, the indicator hand will continue to move, always pointing north. After 20 seconds, the compass will automatically turn off and the indicator hand will return to the previous function indicator. This conserves battery life. Press C (COMPASS) at any time to keep the compass on for another 20 seconds.

Note: During compass operation, the second hand moves in two-second increments.
