Suunto Ocean lost in Bali — strap detached while surfing
-
Hi everyone,My name is Alexey Chepik. I am a yacht professional and a long-time Suunto user. I am posting this to share a specific engineering vulnerability regarding the Suunto Ocean original silicone strap architecture, which recently resulted in the total loss of my device while surfing in Bali.As a professional working at sea, I want to analyze this incident strictly from a mechanical and hydrodynamic standpoint, rather than attributing it to basic “user negligence.” There was no high-impact crash, wipeout, or contact with the reef. The failure occurred during standard swimming strokes in shallow water.The Failure Mechanism (Technical Breakdown):Keeper Instability (Strap Loops): During repetitive high-velocity water movement (paddling/swimming strokes), the loose end of the original silicone strap frequently slips out of the two retaining loops (keepers). This is a known issue where the friction coefficient of the silicone isn’t sufficient to hold the tail under water turbulence.Hydrodynamic Lever Effect: Once the strap tail is free, the water flow gets underneath the strap, creating massive lateral hydrodynamic drag. Because the silicone material is highly flexible, this drag forces the strap to twist at an angle near the watch lugs.Accidental Quick-Release Engagement: The Suunto Ocean uses standard 22mm Quick-Release spring bars with an exposed integrated lever pin. When the strap flexes laterally under water pressure, the compressed silicone edge deforms and pushes directly against the quick-release micro-lever. This mechanically retracts the spring bar pin out of the lug socket, causing immediate chassis detachment.For a certified diving instrument (conforming to EN 13319 standards), the primary retention system must be bulletproof against natural water resistance. The combination of loose strap keepers and an easily reachable quick-release mechanism creates a structural risk during high-drag water sports like surfing or fast surface swimming.I have already contacted global support (support@suunto.com), services, and legal departments. However, I highly recommend that the Suunto engineering team reviews the tolerance of the 22mm quick-release spring mechanism and considers more secure, rigid pins for water-sport heavy devices.Has anyone else noticed the strap keepers slipping out during water activities, or faced structural detachment under hydrodynamic load? I love the Suunto ecosystem and truly hope the team will look into my case individually to help me stay with the brand.Thank you, and stay safe in the water.

@seaman-life sorry to hear. But our of ignorance from my part—isn’t this why real diving watches has either drilled or fixed lugs and utilise either NATO or bracelets? There is basically no force in the world that would rip the bracelet (or my rubber strap with deployment clasp) off my Seiko Tuna.
