• How do I charge my Citizen Eco-Drive watch?

  Eco-Drive watches charge via exposure to any light source. For a full charge, expose the watch dial to direct sunlight for several hours. Indoor lighting also charges the watch but takes significantly longer.

• What does it mean if my Citizen watch second hand skips two seconds?

  If the second hand jumps in 2-second intervals, it indicates the low-charge warning mode. Expose your watch to bright light immediately to recharge it completely.

• How do I set the time on my Citizen watch?

  For most analog models, pull the crown out to the second click (position 2), rotate it to adjust the hands, and push it back in. For radio-controlled or complex digital models, refer to the specific movement caliber manual.

• Where can I find the movement caliber number on my watch?

  The movement caliber number is typically engraved on the case back. It consists of four alphanumeric characters (e.g., E870, U830) often followed by a hyphen and case number.

• Is my Citizen watch water-resistant?

  Water resistance depends on the model. 'Water Resist' typically handles splashes; 'WR 50/100' is suitable for swimming; 'VR 200' or 'Diver's' models are suitable for diving. Check the case back inscription for your specific rating.
