Formex REEF GMT Automatic COSC 300M "Black/Blue" 42mm

The Formex Reef GMT expands on the concept of the original Reef with a full GMT function, allowing up to three time zones to be tracked simultaneously – without compromising on robustness, finish, or the patented interchangeable bezel and strap systems.

At the specified price, the watch is supplied exclusively on the Formex solid stainless steel bracelet with quick-release system and integrated fine adjustment. Optionally available mesh, leather, and rubber straps, as well as their corresponding clasps, are not included in the scope of delivery.

The 42mm stainless steel case is powered by a COSC-certified Sellita SW330-2 GMT automatic chronometer movement. The skeletonized rotor is visible through the sapphire crystal case back, underscoring the watch's high-tech character.

Thanks to its slim caliber, the Reef GMT measures only 11.4 mm in height and appears particularly slender on the wrist with a perceived height of approximately 9.4 mm. The double gasket construction and screw-down crown ensure a water resistance of 300 meters.

Scope of Delivery

At the specified price, the watch is supplied with the following bracelet:

• Formex solid stainless steel bracelet
• Quick-release system
• Integrated fine adjustment
• Tool-free strap change

Optionally available stainless steel mesh, leather, and rubber straps, as well as separate Formex folding clasps, are not included in the scope of delivery.

GMT Function

The Sellita SW330-2 allows for the display of an additional time zone via the central 24-hour GMT hand.

In conjunction with the bidirectional 24-hour bezel, a third time zone can be read. This makes the Reef GMT particularly suitable for travel, international business appointments, and contact with different time zones.

Bidirectional Rotating GMT Bezel

The bidirectional rotating GMT bezel is made of particularly scratch-resistant zirconium oxide ceramic or stainless steel, depending on the version.

Variants with a white scale are filled with Swiss BGW9 Super-LumiNova and glow blue in the dark.

The 48-click mechanism allows for precise setting of the third time zone. Thanks to the patented Formex system, the bezel can be removed without tools and exchanged for other compatible variants.

Additional bezels are not included in the scope of delivery and can be purchased separately as an option.

Dial

The dials of the Reef GMT are manufactured in Formex's in-house facility in the Swiss Jura. Each color variant receives a hand-applied dégradé gradient, which darkens towards the edge and is combined with a fine sunray finish.

The triangular rehaut indices are hand-applied and harmonize with the broad, faceted hands. Polished chamfers and brushed surfaces create a varied play of light.

Hands and indices are generously filled with BGW9 Super-LumiNova, ensuring clear readability day and night. The applied Formex logo completes the high-quality overall impression.

COSC-Certified GMT Automatic Movement

Inside works the Swiss Made Sellita SW330-2 automatic movement in chronometer quality.

The movement features:

• GMT or 24-hour display
• Date display with quick adjustment
• 25 jewels
• Glucydur balance
• Automatic winding in both directions
• Skeletonized Formex rotor

Each movement undergoes the official COSC chronometer test and receives an individual chronometer number. Formex also checks the movement after assembly to ensure high precision of the fully assembled watch.

Stainless Steel Bracelet and Wearing Comfort

The included solid stainless steel bracelet features a quick-release system and integrated fine adjustment.

This allows the bracelet length to be comfortably adjusted to changes in wrist circumference throughout the day. The bracelet can be removed from the watch within seconds without tools.

Additional strap variants are available separately for the Reef GMT:

• Stainless steel mesh bracelet with quick-release and fine adjustment
