What’s better than owning a stylish go-anywhere, do-anything tool watch? One that’s also highly customizable with interchangeable bezels and straps to nail a range of looks. If you haven’t already, meet the Formex Reef watch line, which, thanks to bezels and bracelets that can be easily swapped out without tools across two main models, is superbly versatile.

The two main models are the Formex Reef Automatic Chronometer 300M diver and the Formex Reef GMT Automatic Chronometer 300M, which both share the same case construction to allow for interchangeable parts. Those cases measure 42mm, are 11.4mm thick, and are water-resistant to 300 meters (1,000 feet) deep. Dimensions and performance aside, it’s the case silhouette that defines the Reef watch whereby a protruding “ear” on the left-hand side of the case mimics the shape of the crown guards on the right to provide visual symmetry.

The duo of Reef models benefit from the patented tool-free interchangeable bezel system and all bezels are exchangeable. That means GMT and dive bezels are compatible with both the Reef GMT and Reef Dive watches. Developed by Formex engineers, the unique bezel mounting system permits wearers to swap out the bezel with just a flick of the wrist. Additional bezels are sold separately if Reef watch owners wish to build their accessories collection.

Formex currently offers six GMT bezels: black ceramic with luminous markings, blue/black ceramic with luminous markings, green ceramic with luminous markings, black ceramic with rose gold lacquer markings, green ceramic with rose gold lacquer markings, and stainless steel with black lacquer markings — all of which feature a sunburst finish. Conversely, there are four dive bezels available: black ceramic, blue ceramic, green ceramic, and stainless steel — all of which include three-dimensional graduations and numbers engraved by femto-laser pulsations. Of course, the GMT bezels include 24-hour scales while the dive bezels include 60-minute scales. Furthermore, the Reef diving watches have a click spring to allow for unidirectional bezel rotation (120 clicks) whereas the Reef GMT watches feature a piston ratcheting system for bi-directional bezel rotation (48 clicks).

Switching out straps is also a breeze due to the Reef’s quick-release system and all straps and bracelets are compatible across both main models. From leather, NATO, and rubber straps to steel three-link and Milanese mesh bracelets, the options are generous. A departure from traditional mesh bracelets, the Formex Milanese bracelet features a multi-position adjustable clasp (similar to the original solid-link steel bracelet) with a 10mm patented fine-adjustment extension system to find that perfect fit around the wrist. Yet again, additional straps are available for purchase to maximize the variety of different styles achievable with one watch. However, if you already have a large collection of straps, you’ll be happy to know that Reef GMT and Reef Dive watch cases are compatible with any conventional straps with straight springbars, and the lug widths are 22mm.

The dials of the Reef watches, which are produced at the company’s in-house dial manufacturer, include sloped triangle-shaped applied indices, broad hour and minute hands, and a long sweeping seconds hand with a lume plot towards the end. Although the GMT and diver share the same hour marker and handset silhouettes, all coated with Swiss Super-LumiNova® BGW9 lume for a long-lasting blue glow in low light, the GMT, naturally, includes an additional 24-hour arrow-tipped hand to display the second time zone. Moreover, both models also have a date window above 6 o’clock, color matched to the dial. In true Formex fashion, dial options are varied within both Reef sub-collections. GMT variants come with the choice of black, green, and white dials, in addition to various colors for the indexes and 24-hour hands. Diver variants offer black, blue, green, silver, white, and radiant bronze dials, the last of which is a striking new addition to the collection.

Given their divergent functionalities, the movements differ between the pair of Reef watches. The Reef GMT runs on the COSC-certified Sellita SW330-2 GMT automatic movement with a 56-hour power reserve. The movement is fully decorated, complete with blued screws and a custom skeletonized rotor, which is visible from the exhibition caseback. In contrast, the Reef diver is equipped with the COSC-certified Sellita SW300, also with a 56-hour power reserve. While it is also fully decorated with a custom skeletonized rotor, the movement is hidden behind a closed steel case back.

Commenting on the Reef collection, Formex CEO, Raphael Granito, said: “The Reef collection has always represented the perfect blend of refined styling and rugged tool watch capabilities. It was created with the belief that high-performance tools can also be elegant, and the original Reef diver is the watch that I choose to wear when I want a timepiece that can effortlessly make the transition from a day of surfing at the beach to a nice evening of dinner and drinks. The Formex Reef GMT Automatic Chronometer 300M expands upon this highly versatile concept to create the perfect go-anywhere, do-anything travel watch that is built to explore the globe and designed for individuals with a life of adventure.”

Prices for the Formex Reef GMT Automatic Chronometer 300M range from $1,860 to $2,310 USD whereas prices for the Formex Reef Automatic Chronometer 300M range from $1,830 to $2,065 USD, depending on the dial, bezel, and strap chosen. Additional bezels are priced from $170 to $225 USD while additional straps and bracelets are priced from $85 to $415 USD. The interchangeable bezels and straps, along with the wide assortment of dials on offer, make it easy to not only find the perfect Formex Reef watch to suit your style but also change it up whenever the mood strikes.
