SwiftLink Compatibility: Grand Seiko Models

Initially, we're launching the GS Extension Link for bracelets with removable links of 18mm width and a central unit width of 9.9mm. We'll offer three finish versions: the 5-bead style with two mirror-polished accents, the 5-bead with two brushed accents, and the 3-bead all-brushed version.

These are designed to cater to the most popular GS models and fit the most common sizes. While our link is compatible with a wide range of models, we encourage customers to verify compatibility for their specific watch. 

For a quick check, a ruler can be used, but for precision and assurance, calipers are recommended.
