This bracelet is not made by Seiko
The bracelet is delivered without end-pieces, the original end pieces are the best fit to the watch case and can be combined with this bracelet.
The SNXS-models are produced by Seiko with a kind of Presidential bracelet that has very tiny folded links. It is difficult to adjust the length because of this. This folded links also feal a bit cheap and the length is only suitable for 20cm wrist at the most.
This solid oyster bracelet is suitable for wrists up to 22cm! The links are screwed, a 1.4mm screw driver is perfect to unscrew these small screws (I use something like loc-tite on the thread to keep these screwes from unscrewing too easily). It is to be used together with the original end pieces.
You can choose the standard clasp, to be opened with you nail. It has a little tab that facilitates this). The clasp has 6 adjustment holes, one more than the original clasp, it is attached to the bracelet on one side, so it cannot be changed. the connecting parts are made of flat steel.
I also have a solid clasp, newly developed. This clasp is very solid and opens by pressing the tabs on the sides. It also has 6 adjustment holes. This clasp is made of thick steel, with a brused finish, and the connecting pieces are made of thick steel too.
