The wristwatch, a timepiece worn on the wrist, is so commonplace today that it's easy to forget it was once an innovation that reshaped how we perceive time and convenience. While its evolution spans centuries, the wristwatch’s journey from a niche accessory to an essential tool and style symbol is fascinating.

As Featured on MONOCHROME: The ZRC Grands Fonds Heterium — A Serious Dive Watch Contender
When MONOCHROME Watches — one of the most respected voices in the horology world — dives deep (literally) into a watch, people listen. Their recent hands-on review of the ZRC Grands Fonds Heterium not only showcases the technical brilliance of this new model but also elevates ZRC to elite status in the dive watch game.
So what makes this watch stand out? Broken down through the eyes of MONOCHROME’s in-depth field test.
Tested Where It Counts: Underwater
The ZRC Grands Fonds Heterium wasn’t just reviewed in a studio — it was tested in its natural habitat: underwater.
As the MONOCHROME team explains in their article, this watch “felt right at home” under the surface. From the bezel's grip to the legibility of the dial, every feature passed with flying colors. And that’s not surprising. ZRC’s roots are tightly wound around true professional use—the brand was originally commissioned by the French Navy back in the 1960s.
“It just feels right underwater,” the reviewer states. A nod to the fact that this isn’t just a watch with dive specs on paper—it’s a tool that delivers in the real world.
What Makes the Grands Fonds Heterium Unique?
Here are a few standout features from the MONOCHROME review:
Heterium Alloy Case: A brand-new, proprietary material engineered by ZRC that offers superior resistance to saltwater corrosion—a major innovation in the world of dive watches.
Crown at 6 o’clock: This isn't just quirky design—it’s a solution. The crown placement, combined with the locking bracelet system, ensures the crown is always fully screwed in before diving.
ECS (Easy Clean System): ZRC’s patented bezel cleaning system that prevents salt build-up—designed to keep the mechanism working perfectly over time, especially in harsh marine environments.
Final Thoughts from MONOCHROME
Perhaps the strongest praise comes right at the end of the review, where the team doesn’t hold back:
“As their technical and military chops put them up there with the Tudors and Rolexes of the watch world.”
That’s no small statement. ZRC, a brand with genuine military heritage and a focus on tool-first design, is being compared to legends. And with the Heterium, they’ve proved they belong in that conversation.
