Eco-Drive watches do not need batteries replaced.

It is speculated that initial capacities may wane up to 20 per cent over 20 years however, we do not expect this to interfere with the use of the watch. What are the life spans of solar cells and rechargeable cells?Īccording to our data, both solar and rechargeable cells will last more than 10 years. We recommend you expose your Eco-Drive to the sunlight from time to time. Also, in winter, watches tend to be kept under sleeves of overcoats or thick jackets that hinder the absorption of light energy. Recharging varies according to the illuminance from the source of light: in winter the required time for recharging is longer than summer, because the illuminance of the sun is weaker.

Does recharging time vary with the seasons? As long as the dial is exposed to light regularly, the watch rarely stops. Can Eco-Drive watches be recharged under fluorescent lamps? Once exposed to light, the hands move very quickly to catch up to the correct time, which has been tracked internally by the watch. Why?Įco-Drive watches with the Power Saving feature stop the second hand to save energy when away from light (in the dark, a drawer or under sleeves, for example). The second hand runs very quickly, then resume normal operation. After recharging and adjusting your watch, the second hand will resume normal operation. The irregular interval movement indicates that the time shown is incorrect because the watch stopped once then started again. This is the Time Setting Warning feature. The second hand moves at irregular intervals, such as 1-second, 1-second and 2-second. Once the battery is fully charged, the second hand will resume normal operation. This is the Insufficient Charge Warning feature, and indicates the battery is not yet charged enough. The second hand jumps in 2-second intervals. Estimates are detailed in your instruction book. The amount of charging time required varies depending on model and light conditions. Your Eco-Drive watch will charge in one third of the time if you pull out the crown while charging under normal charging conditions. When the Eco-Drive watch stops, what should be done to restart it?Įxpose the Eco-Drive to the light.
