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. Drawing from a tradition of high-end watch production, it develops and produces models that meet the highest quality standards in the industry, 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 39.5 mm
A true diver's watch at its core – the 39.5 mm steel case houses a COSC-certified automatic Sellita SW300 movement of the highest quality, utilizing chronometer-grade components. This slim and precise caliber has allowed for an overall thickness of only 11 mm and an optical height of 9.4 mm, making the REEF model suitable for more elegant occasions as well. For underwater use, the double-sealed construction is tested for water resistance up to 300 m.
The unidirectional rotating bezel, as one of the most exposed parts, is made of extremely hard and scratch-resistant zirconium oxide 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 cutouts on the edge of the bezel ensure an ideal grip for safe setting and monitoring of dive time or decompression stops. The 120-click mechanism is smooth and precise, yet firm. Furthermore, the bezel can be easily replaced even without tools.
COSC Chronometer Certified Performance
When it comes to timekeeping accuracy, the gold standard is COSC Chronometer certification. The Contrôle Officiel Suisse des Chronomètres (COSC) is the official Swiss chronometer testing institute, an independent body that certifies the accuracy and reliability of Swiss Made watches. The "Chronometer" designation can only be obtained for movements of the highest quality that successfully pass a rigorous 15-day series of tests. It signifies 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 accuracy and performance within Swiss watchmaking. Only about 6% of all watches produced in Switzerland achieve this prestigious designation, representing some of the most accurate and reliable mechanical timepieces in the world.
