The Fallacy of False Priorities, Watch Edition

“The double-minded man is unstable in all his ways.” Guilty as charged. Case in point: my tortured relationship with FKM Divecore straps.

The Notre Dame study had me spiraling—researchers tortured the material with solvents, heat, and abrasion until they squeezed out PFAS “forever chemicals” and then warned these might leach into human skin. Ever since, I’ve gone back and forth, back and forth, like a malfunctioning metronome, on whether to keep wearing the straps I love more than any other rubber I’ve tried in two decades of watch collecting.

Of course, no one wants to think of their wristwear as a poison delivery system. But context matters. First, FKM is highly stable under real-world conditions; the lab tests were more horror show than practical scenario. Second, it’s the manufacturing process that endangers workers, not the end-user. Third, if we’re ranking PFAS risks, drinking unfiltered water, eating from PFAS-coated packaging, or cooking on scratched Teflon are solid tens on the risk scale, while wearing an FKM strap is a lonely little one. That’s the Fallacy of False Priorities: panic over the trivial while ignoring the obvious.

Even so, the issue isn’t a Nothing Burger. Divecore’s own Paul admits handling FKM worries him, and he’s working on alternative materials—silicone, vulcanized silicone, HNBR—to protect his workers and reassure consumers. That’s just smart business.

Meanwhile, I’m not without options. My strap drawer holds factory Seiko silicones and urethanes, plus top-tier Tropic straps made of vulcanized rubber. They’re fine, but none hold a candle to the sleek perfection of Divecore FKM. I tried swapping them in, but they feel like consolation prizes—serviceable, never glorious.

So I made a deal with myself: enjoy my pristine FKMs for now, and when the new HNBR or silicone Divecore straps arrive, I’ll switch. Sounds reasonable. Except once you’ve let the idea of PFAS seeping into your skin lodge in your brain, it refuses to leave. I’ve written about it on Instagram, made a YouTube video, and now I’m stuck in an obsessive loop, second-guessing every strap change as though I were rewriting my will.

Which brings me back to my original point: the double-minded man is unstable in all his ways. And right now, that man is staring at seven watches, toggling between glory and paranoia, wishing he could strap on peace of mind.
