Frequently Asked Questions
Is IP68 waterproofing good enough for open‑water swimming?
IP68 indicates strong protection against dust and immersion in water and is fine for surface and open‑water swims. It’s not the same as a high ATM dive rating — avoid deep dives or high‑pressure underwater activities, and always rinse the watch with fresh water after saltwater swims to preserve seals and band materials.
How tight should my band be to get accurate heart‑rate readings while swimming?
Aim for snug contact without restricting circulation. The band should sit firmly so the optical sensor stays flush to skin when your arm moves through the water; micro‑adjustable holes or fine buckles help dial in that balance for both comfort and consistent readings.
What’s the best way to care for a band after an ocean swim?
Rinse the band and watch thoroughly with fresh water as soon as possible, dry with a soft cloth, and allow the band to air dry completely before storage. For silicone/TPU bands, avoid strong detergents and prolonged sun exposure. Swapping to a fresh spare band between sessions extends the life of both band and device.
