Important Notes
- The 20mm version is not compatible with the Samsung Gear S2 or Samsung Galaxy Watch (2019, 46mm model).
- Before purchasing, measure the distance between your watch lugs (the space where the band attaches) to confirm the correct width.
- Leather is a natural material and may develop slight variations in texture and color over time—this is normal and adds to its character.
- To maintain appearance, avoid prolonged exposure to water, sweat, or direct sunlight. Clean gently with a dry cloth when needed.
- Package includes one leather band, one spring bar tool for installation assistance, and a quality control card for product verification.
