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 daily use”, please do not wash the watch.

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)
* Lumibrite 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.
