Description
Formex Swiss Made Watches, founded in 1999, is an independent, family-owned watch manufacturer based in Biel/Bienne – a city considered the cradle of Swiss watchmaking. Building on the tradition of high-end watch production, Formex develops and produces models that meet the industry's highest quality standards, complemented by unique technical solutions for enhanced functionality and comfort.
Thanks to an innovative distribution model, Formex offers an accessible entry into the world of luxury watchmaking for all who appreciate precise craftsmanship and exceptional artistry.
REEF 42 mm
A true diver's watch at its core – the 42mm steel case houses a top-grade COSC-certified Sellita SW300 automatic movement, utilizing components intended for chronometers. This slim and precise caliber has allowed for an overall thickness of only 11.4mm and an optical height of 9.4mm, making the REEF model suitable for more elegant occasions. For underwater use, the double-gasket construction is tested for water resistance up to 300m.
The unidirectional rotating bezel, as one of the most exposed parts, is made of extremely hard and scratch-resistant zirconium dioxide ceramic. The scale and numerals are engraved using femtolaser pulses, with each bezel requiring approximately 60 minutes of precise engraving to achieve a three-dimensional effect.
The serrated cut-outs on the bezel's edge ensure an ideal grip for safe setting and monitoring of dive time or decompression stops. The 120-click mechanism is smooth and precise, yet robust. Furthermore, the bezel can be easily replaced without the need for tools.
COSC chronometer certified
When it comes to timekeeping accuracy, the gold standard is the COSC Chronometer certification. The Contrôle Officiel Suisse des Chronomètres (COSC) is the official Swiss chronometer testing institute, which, as an independent body, certifies the accuracy and reliability of Swiss Made watches. The "Chronometer" designation can only be obtained by movements of the highest quality that successfully pass a rigorous 15-day series of tests. This means that the given caliber achieves the highest standards of mechanical reliability and precision.
Formex watches are powered by COSC Chronometer-certified movements, ensuring the highest level of precision and performance in Swiss watchmaking. Only approximately 6% of all watches produced in Switzerland receive this prestigious designation, making them among the most accurate and reliable mechanical timepieces in the world.
