We recommend that you use natural outdoor light, or an incandescant light source 20" from the watch for charging a watch in this state. However, office light is sufficient for keeping your watch continually charged.

Please Note:

After a full recharge from a low or no charge state, it will be necessary to perform an all reset and in some cases a 0-positioning. If this is not done, your watch may not operate correctly.

For simple analog models, pull the crown out the time setting position, leave there for 30 seconds, return the crown to the closed position next to the case, then set the time. For other than simple analog models (perpetual calendar, multi-function and specialty pieces), please refer to your instruction manual or the instruction sets on our web site for the all reset and 0-positioning procedures.
