【Selection Guide】This watch band is available in three widths: 18mm, 20mm, and 22mm. Each width comes in both "Regular Length" and "Extension Length" options (💡18 mm/20 mm extension models come with 2 extra links compared to the standard version, while the 22 mm extension model comes with 3 extra links). To ensure a perfect fit for your watch, please accurately measure the lug-to-lug distance (in millimeters) and select the strap with the corresponding width.

【One-Piece Expansion Watch Bands】The strap features an elastic, expandable design for easy and effortless wearing, making it particularly suitable for the elderly. 💡Please note: due to the one-piece molded construction, the strap length is not adjustable. Please refer to the compatible wrist circumference indicated in the product images before ordering (this data is based on actual measurements using a Hearkent watch case paired with the strap).

【Compatibility】Compatible with most smartwatches and traditional watches. To ensure the expansion band fits your watch precisely and wears comfortably, 💕it is recommended that you measure two key specifications in advance: your watch's inner lug width (mm) and your personal wrist circumference.

【Material & Packaging】Each strap is individually packaged and includes one elastic, expandable stainless steel strap, suitable for both men and women. Made from high-quality, smooth-touch matte stainless steel, it is waterproof and sweatproof, offering greater convenience for daily wear.
