Apparently Apple has been receiving some complaints from people with very large wrists. Why am I saying this? Well, today the company started selling two accessories for the Watch which can be used by people with wrists up to 245mm!

The first one is the L / XL sports bracelet (for wrists ranging from 195mm to 245mm); this larger size, however, is only available in black or white and costs the same $ 49 as the others.

If you have a 42mm Link Bracelet, you can now buy a kit (US $ 49) that has six additional pieces, making the bracelet suitable for people with wrists between 205mm and 245mm.
No special tool is needed to remove / place these extra parts on the bracelet as they have a mechanism very similar to what the Watch itself has to exchange bracelets. In the case of Link Bracelet, instead of squeezing a button and sliding it to the side, you squeeze a button and fit the link over it.
See the list of bracelets and sizes currently available:

It is worth noting that those who need these larger bracelets have to purchase everything separately. It is not possible to buy a watch with an L / XL sports band or the Apple Watch.

On a related note, the modern buckle bracelets (Modern Buckle) are now available for purchase individually ($ 249) before, it was only possible to purchase one of these by buying the watch. All of this, of course, in countries where the Apple Watch is already being marketed.
