Important Notes

While the watch is designed for diving and water exposure, it should not be used for high-velocity water sports such as jet skiing or water skiing without confirming specific manufacturer guidelines. Regular maintenance, including pressure testing every 1–2 years, is recommended to preserve water resistance. Avoid exposing the crown or pushers to water unless confirmed to be sealed. The product comes with a manufacturer’s warranty; for details, customers should refer to the official Spinnaker warranty policy. Packaging includes the watch, instruction manual, and warranty card. Always ensure the watch is properly secured with the clasp to prevent loss during activity.
