Formex Reef 39.5mm Review: A True Go-Anywhere, Do-Anything Watch?

For watch enthusiasts considering a Formex Reef 39.5mm, we’ve come across a fantastic YouTube review that gives deep insights into this Swiss-made timepiece. The video, produced by SoCal Watch Reviews, offers a detailed hands-on experience with the Reef, covering its specs, unique features, and real-world wearability. If you’re on the fence about buying this watch, this review is definitely worth watching.

First Impressions: A Watch That Surprises in Person

The reviewer, Miguel from SoCal Watch Reviews, admits that he wasn’t immediately drawn to the Formex Reef based on pictures and online content. However, once he got hands-on experience with the watch at an event, his perspective changed completely.

This is something that happens often with Formex. As a relatively underrated Swiss brand, Formex doesn’t always get the same attention as bigger names. But for those who give it a chance, the brand delivers outstanding quality at a fraction of the cost of high-end luxury competitors.

What Makes the Formex Reef 39.5mm Special?

Formex has been making watches since 1999, but since Rafael Granito took over the company in 2016, the brand has stepped up its game. The Reef series, in particular, highlights Formex’s dedication to precision, build quality, and innovation.

  • Case Size: 39.5mm diameter, 45.5mm lug-to-lug
  • Thickness: 11mm
  • Lug Width: 22mm

  • Movement: COSC-certified Sellita SW300-1 (high accuracy, -4/+6 seconds per day)
  • Power Reserve: ~56 hours
  • Bezel: Unidirectional 120-click ceramic bezel with tool-free quick-swap system
  • Dial: Multi-layered lacquer with applied indices
  • Straps: Quick-release bracelet, NATO, and rubber strap with carbon fiber folding clasp

Why the Quick-Swap Bezel System Stands Out

One of the standout features of the Formex Reef is its quick-release bezel system. Unlike most dive watches that require tools for bezel changes, the Reef allows for effortless swapping. This means you can switch from a classic black bezel to a vibrant blue or green one in seconds, completely transforming the look of your watch.

Miguel from SoCal Watch Reviews tested this feature and praised the precision and ease of use. If you enjoy changing the aesthetics of your watch without the hassle of tools, this is a game-changer.

Dial & Legibility: A White Dial Done Right

The reviewer opted for the white lacquer dial, a color choice he initially lacked in his collection. Formex’s dial design is far from basic—it’s created using a seven-layer lacquer process to achieve an impressive depth effect. The applied triangle-shaped indices add extra dimension, while the BGW9 Super-LumiNova ensures excellent legibility in low-light conditions.

Bracelets & Straps: Versatility at Its Best

Formex is known for its exceptional comfort and strap versatility, and the Reef is no exception. The included options provide an all-in-one package:

  1. Stainless Steel Bracelet: Solid, premium feel with a micro-adjustment system for quick sizing changes.
  2. Mesh-Style Bracelet: Adds a sportier, slightly vintage aesthetic.
  3. NATO Strap (by WatchGecko collaboration): A high-quality, rugged option for casual wear.
  4. Rubber Strap: Features a carbon fiber composite folding clasp with built-in fine adjustment.

While the bracelet is well-made, the reviewer noted that it feels a bit chunky. A slight taper from 22mm to 18mminstead of 22mm to 20mm could have improved comfort and elegance.

Performance: A COSC-Certified Powerhouse

Inside, the Sellita SW300-1 movement ensures chronometer-level accuracy. In Miguel’s testing, the watch was running at about -1 second per day, which is impressive for a Swiss automatic watch at this price point.

Final Thoughts: Is the Formex Reef 39.5mm Worth It?

The Formex Reef punches above its weight class. It’s a serious alternative to luxury Swiss dive watches at a much more affordable price. From the high-end finishing to the innovative bezel and bracelet systems, it’s a perfect everyday sports watch with true enthusiast appeal.

If you’re in the market for a versatile Swiss dive watch that blends innovation, craftsmanship, and value, the Formex Reef is worth considering. And if you want a detailed, hands-on look, we highly recommend watching the full SoCal Watch Reviews YouTube video above.
