Charging the battery
■ How to charge the battery
Expose the dial to light to charge the watch.
To ensure optimal performance of the watch, make sure that the watch is kept sufficiently charged at all times.
text_image
Diagram showing a hand gesture with an 'X' mark and a close-up of a hand holding a wrist, next to a device with a cross symbol.Under the following situations, the energy of the watch is likely to be depleted, resulting in stoppage of the watch:
• The watch is concealed under a sleeve.
• The watch is used or stored under conditions where it cannot be exposed to light for a long time.
* Be careful to make sure that the watch does not get hot when it is charging. (The operating temperature range is -10°C to +60°C.)
* When you first start using the watch or starting it after it stopped due to a lack of charge, charge the watch sufficiently using the table on P. 34 as a guide.
EN 33
■ Guide to charging times
Charge the watch using the times below as a guide.
| Illuminance lx (LUX) | Light source | Condition (Example) | Time required for fully charging the watch | Time required to get the small seconds hand moving at one-second intervals | Time required for charging the watch to last for 1 day |
| 700 | Fluorescent light | General offices - | 60 hours 2.5 hours | ||
| 3,000 | Fluorescent light | 30W 20cm 110 | hours 13 hours | 33 minutes | |
| 10,000 | Fluorescent light | 30W 5cm | 30 hours | 3.5 hours | 9 minutes |
| 10,000 | Sunlight | Cloudy day | 30 hours | 3.5 hours | 9 minutes |
| 100,000 | Sunlight | Sunny day (Under the direct sunlight on a summer day) | 5 hours | 36 minutes | 2 minutes |
The figures of "Time required for charging the watch to start moving at one-second intervals" are estimations of time required to charge the stopped watch by exposing it to light until it moves at steady one-second intervals. Even if the watch is partially charged for a shorter period, the watch will resume one-second-interval movement. However, it may shortly return to two-second-interval movement. Use the charging time in this column as a rough guide for sufficient charging time.
* The required charging time slightly varies depending on the model of the watch.
EN 34
About energy
■ How to display the energy level
On the "charge level display", the energy level hand indicates the energy level. "Toggling between displays" → P. 19
| Display | |||
| Energy level | Full Approximately half-full | Low | |
| Approximate length of continuous operation | At least 100 days | 2 days to 100 days | Less than 2 days |
| Solutions | Continue to use in current state | Use while paying attention to recharging | The small seconds hand will start “2-second movement” in which it moves every 2 seconds. Please charge until fully charged.* If the stopwatch is used, it will automatically reset and the display will change to the ‘charge level display’. |
* Please be aware that immediately after charging, the energy level display may show a level one higher than the actual level.
EN 35
Daily care
● The watch requires good daily care
- Do not wash the watch when its crown is in the extended position.
- Wipe away moisture, sweat or dirt with a soft cloth.
• After soaking the watch in seawater, be sure to wash the watch in clean pure water and wipe it dry
carefully
Do not pour running water directly from a faucet onto the watch. Put some water into a bowl first, and
then soak the watch in the water to wash it
* If your watch is rated as "Non-water resistant" or "water resistant for everyday life", do not wash the watch.
*Performance and type* → P. 37
● Turn the crown from time to time
• In order to prevent corrosion of the crown, turn the crown from time to time.
• The same practice should be applied to a screw down crown.
"Screw down crown" → P. 17
- Press the buttons once in a while
- Press the buttons once in a while to prevent corrosion of the buttons
• The same applies to the screw-locked buttons.
"Screw lock type button" → P. 18
Lumibrite
If your watch has Lumibrite
Lumibrite is a luminous paint that absorbs the light energy of sunlight and lighting apparatuses in a short time and stores it to emit light in the dark. For example, if exposed to a light of more than 500 lux for approximately 10 minutes, Lumibrite can emit light for 3 to 5 hours. Please note, however, that, as Lumibrite emits the light it stores, the luminance level of the light decreases gradually over time. The duration of the emitted light may also differ slightly depending on such factors as the brightness of the place where the watch is exposed to light and the distance from the light source to the watch.
In general, when coming from a place that is bright to a place that is dark, it takes human eyes some time to adapt
to the darkness making it difficult to see objects initially. [Dark adaptation]
Lumibrile is luminous paint that stores and emits light, which is harmless to human beings and the environment,
containing no toxic materials such as radioactive substances.
| Condition Illumination | |
| Sunlight | Fine weather 100,000 lux |
| Cloudy weather 10,000 lux | |
| Indoor (Window-side during daytime) | Fine weather more than 3,000 lux |
| Cloudy weather 1,000 to 3,000 lux | |
| Rainy weather less than 1,000 lux | |
| Lighting apparatus (40-watt daylight fluorescent light) | Distance to the watch: 1 m 1,000 lux |

When the secondary battery is fully charged, the overcharge prevention function is automatically activated to avoid further charging.
There is no need to worry about damage caused by overcharging no matter how much the secondary battery is charged in excess of the "time required for fully charging the watch."
* For the required time to fully charge the battery, see 'Guide to charging times' → P. 34.
WARNING
■ Notes on charging the watch
- When charging the watch, do not place the watch in close proximity to an intense light source such as lighting equipment for photography, spotlights or incandescent lights, as the watch may be excessively heated resulting in damage to its internal parts.
- When charging the watch by exposure to direct sunlight, avoid places that easily reach high temperatures, such as a car dashboard.
• Always keep the watch temperature under 60°C.

Magnetic resistant performance
Affected by nearby magnetism.
a watch may temporarily gain or lose time or stop operating.
Diver's watches feature magnetic resistant performance which is equivalent to or above JIS Class 1.
DANGER
| Indication on the case back | Condition of use |
| No indication | Keep the watch more than 5 cm away from magnetic products.(JIS level-1 standard) |
| Keep the watch more than 1 cm away from magnetic products.(JIS level-2 standard) |
If the watch becomes magnetized and its accuracy deteriorates to an extent exceeding the specified rate under normal use, the watch needs to be demagnetized. In this case, you will be charged for demagnetization and accuracy readjustment even if it happens within the guarantee period.
The reason why a watch is affected by magnetism
The built-in motor is provided with a magnet, which may be influenced by a strong external magnetic field.
EN 41
Band
The band touches the skin directly and becomes dirty with sweat or dust. Therefore, lack of care may accelerate deterioration of the band or cause skin irritation or stain on the sleeve edge. The watch requires a lot of attention for long usage.
● Metallic band
- Moisture, sweat or soil will cause rust even on a stainless steel band if they are left for a long time.
- Lack of care may result in a rash or cause a yellowish or gold stain on the lower sleeve edge of shirts.
- Wipe on moisture, sweat or soil with a soil cloth as soon as possible.
- To sign the soil around the joint zone of the hand, wing it out in water and then brush it off with a soil
- To clean the soil around the joint gaps of the band, wipe it out in water and then brush it off with a solid toothbrush.
(Protect the watch body from water splashes by wrapping it up in plastic wrap etc.)
Clean it off with a soft cloth - Because some titan bands use pins made of stainless steel, which has outstanding strength, rust may
form in the stainless steel parts. - If rust advances, pins may poke out or drop out, and the watch case may fall off the band, or the clasp may not open.
- If a pin is poking out, personal injury may result. In such a case, refrain from using the watch and request repair.
EN 43
● Polyurethane band
- A polyurethane band is susceptible to discoloration from light, and may be deteriorated by solvent or
• Especially a translucent, white. or pale colored band easily adsorbs other colors, resulting in color smears or discoloration. - Wash out dirt in water and clean it off with a dry cloth.
(Protect the watch body from water splashes by wrapping it up in plastic wrap etc.) - When the band becomes less flexible, have the band replaced with a new one. If you continue to use the band as it is, the band may develop cracks or become brittle over time.
Silicone band
- As for material characteristics, the band is easily dirtied, and may be stained and discolored.
- Wipe off dirt with a wet cloth or cleaning tissue.
- Unlike bands of other materials, cracks may result in the band being cut. Take care not to damage the band with an edged tool.
| Notes on skin irritation and allergy | Skin irritation caused by a band may result from various factors such as allergy to metals or leathers, or skin reactions against friction on dust or the band itself. | |
| Notes on the length of the band | Adjust the band to allow a little clearance with your wrist to ensure proper airflow.When wearing the watch, leave enough room to insert a finger between the band and your wrist. | [TRYTK] |
