Elegant Design: Dual Watch Winder with Transparent Acrylic Window to protect your timepiece from scratches while ensuring continuous operation. Its elegant design not only enhances functionality but also serves as a stylish accessory. Premium Adjustable Cushions: The winder accommodates watches with case diameters under 58mm, thicknesses under 28mm, and strap lengths between 180mm and 210mm. Power Requirements: The dual watch winder operates using any standard phone charger (output: 3V–9V, 0.5A). The power adapter is not included. Do not use adapters from other devices. Two Operating Modes:Mode B (Short-Term Run): Winds clockwise for 2 minutes, pauses for 6 minutes, then winds counterclockwise for 2 minutes, repeating this cycle.Mode L (Long-Term Run): Winds counterclockwise for 2 minutes, pauses for 18 minutes, then winds clockwise for 2 minutes, repeating the cycle. The device can be turned off when not in use. Important Note: To prevent your watch from stopping after using the winder, manually wind the crown 20–40 times before placing it inside. This ensures sufficient power reserve. Once fully wound, the watch can be stored in the winder to avoid power depletion. Speed & Compatibility: The winder rotates approximately 970–2,430 turns per day and is exclusively for mechanical watches (not suitable for quartz watches). Please check the TPD (Torsions-Per-Tag) and the rotation direction of the winder according to your watch's instruction manual to ensure correct winding. Description:
