BUILT FOR LIFE . . . AND LONGER
Unlike quartz watches that rely on batteries and plastic components, SEAHOLM mechanical watches are powered by micro-machined metal springs and gears—precision parts designed for lasting accuracy.
But such precision has its vulnerabilities. Magnetic fields can cause these metal components to stick or malfunction, even from something as common as a cell phone. That’s why SEAHOLM movements are engineered to resist extreme magnetic interference—including the intense fields generated by an MRI machine.
How do we do it? Read on.
Engineered to endure a 10-foot drop—equivalent to 15,000 pounds of gravitational force—our watches didn’t just meet the challenge, they exceeded it. Independent testing by Stress Engineering Services revealed zero deviation in accuracy after impact, outperforming traditional watch shock standards by 400%.
Whether you're living at the edge or navigating everyday life, our superior shock resistance ensures your SEAHOLM watch is ready for anything.
Why does this matter? Read on.
Watches rated to 200M under ISO 22810 may sound rugged—but in reality, they’re only suited for bathing, shallow swimming, and light underwater activity. That’s because ISO 22810 doesn’t account for the dynamic pressures of real-world use.
SEAHOLM automatic watches are different. Every model is tested to the highest standard: ISO 6425 – Diver’s 200M. This certification ensures performance under extreme conditions, including deep dives, temperature shocks, and pressure fluctuations.
If it doesn’t say “Diver’s 200M,” leave it on the boat.
"The automatic watch is a marvel of engineering. Well built, they can last a lifetime or more. But SHOCKS, EXPOSURE TO WATER and MAGNETIC FIELDS all adversely affect your watch's performance. The watches that best protect against these forces will be the most durable, reliable and long lasting."
