Feature: Strong Compatibility: This high-quality watch winder features unique rotation modes that are compatible with most mechanical watches. The automatic watch winder supports watches with an elastic strap length range, up to a maximum of 200mm (7.87 inches), and a maximum dial size of 50mm in width and 65mm in length (1.96x2.55 inches). This means it's suitable for most men's and women's watches. Precise Knob Adjustments: Different watch brands and models have different winding requirements. To accommodate a wide range of mechanical watches, we've designed multiple winding modes, including clockwise, counterclockwise, alternating, and intermittent rotations. Combined with independent speed control, the dedicated knobs ensure both reliability and precise timing for your watches. Durable Mabuchi Motor: To enhance stability and durability, we've incorporated a Japanese Mabuchi motor known for its high torque, compact size, precise control, low power consumption, and long lifespan. Plus, two knobs control two watch dials, allowing one dial to accommodate two watches, meeting the needs of different watch models. Practical Details: Our watch box winder features elastic watch pillows, accommodating watches with various strap lengths. The user-friendly open-lid stop function prevents unnecessary wear on the mechanism while allowing easy access to your watches. The blue light adds a touch of luxury, perfect for display and nighttime illumination. With two power supply modes, it's convenient for both home use and portability. Effective Protection: The outer box of the watch turner is crafted with thickened solid wood and a lacquer finish, combined with a high-transparency acrylic clasp door, enhancing texture and aesthetics. The PU interior protects your watches from scratches and impacts and is easy to clean. It is suitable for long-term use by watch enthusiasts and business professionals or as a thoughtful gift for friends and family.
