Formex Reef 39.5 Forged Carbon Dive Watch Review: A Compact Diver with a Unique Twist (2026)

Let's dive into the world of Formex, a watch brand that has been making waves in the industry with its unique approach to engineering and design. Today, we're exploring a new addition to their collection, the Reef 39.5 Forged Carbon, and how it represents a fresh take on the brand's signature style.

A New Look for a Familiar Diver

Formex, with its roots in Biel/Bienne, has carved a niche for itself by prioritizing engineering excellence and ergonomic design. Their Essence and Reef collections have become synonymous with well-crafted, affordable timepieces that offer something different. The Reef collection, in particular, has gained popularity for its robust 300m dive watches, and now, the Baby Reef series has emerged as a standout option for everyday diving.

What makes the new Reef 39.5 Forged Carbon intriguing is its departure from the typical aesthetic. While carbon is often associated with performance and weight reduction, Formex has chosen to highlight its visual and tactile appeal. The result is a watch that's not just about functionality, but also about creating a unique visual experience.

The Art of Adaptation

Integrating forged carbon into the design presented its own set of challenges. The vertically brushed dial, crafted from this unique material, sits on a treated base, ensuring a seamless finish. The signature bevelled date window, a hallmark of Formex's design language, has been carefully preserved through precise layering. Even the dive bezel, with its 120-click functionality, has been engraved using a femtosecond laser and filled by hand with lume, adding a touch of craftsmanship to the overall look.

Unchanged Tech, Enhanced Style

Despite the focus on aesthetics, the technical specifications of the Reef 39.5 Forged Carbon remain unchanged. The applied indices and hands, coated with Super-LumiNova, ensure visibility, a crucial aspect for a dive watch. The compact and balanced 39.5mm case, with its stainless steel exterior and titanium container, houses the COSC-certified Sellita SW300-1 movement, an alternative to the ETA 2892, offering a reliable and accurate timekeeping experience.

Versatility at its Core

One of the standout features of the Reef series is its versatility. The interchangeable bezel system allows wearers to switch between the forged carbon insert and ceramic or steel alternatives, offering a customizable look. Additionally, the quick-release straps, available in steel, rubber, leather, or nylon, paired with Formex's fine-adjustment clasps, ensure a comfortable and adaptable fit for everyday wear.

A Limited Edition, A Unique Experience

The Reef 39.5 Forged Carbon is priced competitively, starting at EUR 1,960 on a strap and EUR 2,070 on a bracelet. What's more, an initial batch of only 100 pieces adds an element of exclusivity to this timepiece. For those who appreciate the fusion of engineering, design, and craftsmanship, this watch offers a unique experience.

In my opinion, Formex's approach to watchmaking is refreshing. They've taken a material often associated with performance and given it a new life, focusing on its visual and tactile qualities. It's a bold move that showcases their commitment to innovation and their ability to create watches that are not just functional, but also visually appealing. This new addition to the Reef collection is a testament to their creativity and attention to detail, and I, for one, am excited to see what they come up with next!
