Compatibility Note

For WD7922 / WD1969PRO / WD0003 Series / WD16570 / WD16570B / WD1993 / WD0014, the last bracelet link on one side is 8mm wide.

If this 8mm end link is connected directly to the OTF adjustable clasp, there may be a small visible gap. For the best fit, we recommend removing the last bracelet link and attaching the second-to-last bracelet link to the clasp instead.

If you’re not sure about compatibility, please contact our customer service for confirmation.
