Unfortunately, we do not have global coverage for online shopping (yet!). Since you are on the international website, please double check if your country is in the country list, and it is marked with a shopping bag icon. If it is, switch to it, and you will be able to purchase products here.
Alternatively, you can try finding a store nearby.
To give it a long life, wipe off moisture, sweat or dirt with a soft cloth when convenient. To wash the band when stains on the surface are noticeable, apply neutral detergent (mixed with some water). For heavy stains, use a tooth brush and remove the stain that has accumulated in the gaps of the band / bracelet segments. After washing, take special care to wipe the gaps of the band/bracelet segments with a towel and dry the entire watch throughly.
