by Brent Robillard

Punching above its weight class

If you’re familiar with Formex, you already know that they punch well above their weight. As a proud owner of the Formex REEF, I’ve always been impressed with the brand’s commitment to high-end finishing, technical innovation, and serious value for money. Frankly, their watches could be priced at double, and I’d still be nodding in approval. Enter the Formex Essence 39 Automatic Chronometer “Blue Agate” Limited Edition—a watch that continues this tradition with effortless style and precision.

Key Features of the Formex Essence 39 Automatic Chronometer

Case and Finishing

The Essence 39 comes in a perfectly proportioned 39mm stainless steel case, measuring a svelte 10mm thick and boasting an ultra-wearable 45mm lug-to-lug. These dimensions hit the sweet spot for just about any wrist, making it a true GADA (Go Anywhere, Do Anything) watch. And let’s talk about the finishing—because, wow, does Formex know how to refine metal.

The interplay of brushed and polished surfaces is simply exquisite. The polished chamfers along the lugs catch the light beautifully, adding a touch of elegance to what is otherwise a robust, everyday piece. Then there’s the case’s unique suspension system—yes, the Essence subtly flexes with your wrist movements, ensuring a ridiculously comfortable fit. It’s like a luxury sports sedan in watch form.

The Dial: Blue Agate Brilliance & Lume That Shines

Now, let’s get to the real star of the show: that dial. The “Blue Agate” name is no exaggeration—this thing is mesmerizing. The horizontally grained texture, paired with the deep, shifting blue hues, creates an ever-changing visual delight depending on the light. It’s not just a dial; it’s an experience.

Then, there’s the lume. Formex doesn’t just do lume—they do it right. The BGW9 Super-LumiNova applied to the hands and indices ensures that even in low light, this watch is as legible as ever. It’s the kind of glow that makes you glance at your wrist in a dark room just for fun (don’t act like you haven’t done it).

Bracelet and Clasp: Comfort & Innovation in One

If you think Formex stops at case finishing and dial magic, think again. The Essence 39’s stainless steel bracelet is a work of ergonomic art, tapering smoothly for comfort. But the real show-stealer? That innovative butterfly clasp with a built-in micro-adjustment system.

No tools, no hassle—just an easy way to fine-tune the fit on the go. Ate too much at lunch? A quick adjustment has you covered. It’s little things like this that make you wonder why more brands aren’t following Formex’s lead.

Movement: COSC-Certified Precision

Under the hood, Formex doesn’t cut corners. The Essence 39 houses a COSC-certified Sellita SW200-1 movement, which means it meets the highest chronometer accuracy standards (-4/+6 seconds per day). It’s a movement you can trust, and the added COSC certification just sweetens the deal. Flip the watch over, and you’ll be greeted by a beautifully decorated movement through the exhibition caseback—a little extra eye candy for the mechanically inclined.
