REEF

Automatic Chronometer COSC 300M

$1,790.00

About This Watch

A true Divers’ watch by design, the 42mm stainless steel watch is powered by a self-winding COSC-certified SW300 that comes in Sellita’s highest quality grade, using top of the line components only found in Chronometer-grade movements. This thin high-precision caliber allowed to construct the REEF at just 11.4mm thickness and a perceived height of 9.4mm, making it a great fit for the elegant occasions alike. For any underwater activities, a double gasket construction is designed and tested for 300 m / 1000 ft of water resistance.

Being one of the most exposed parts, the unidirectional rotatable bezel is made of an extremely hard and scratch-resistant Zirconium oxide ceramic. The graduations and numbers are engraved by femto-laser pulsations. Each bezel takes 60 minutes of precision engraving to achieve its three-dimensional effect. Machined gear-like indentations on the bezel’s edge allow a diver the ideal grip to safely set and monitor diving time and decompression stops. The 60 click action is responsive and smooth, yet offers firm and precise function of the bezel.

The sunray finished dial is manufactured at Formex’s in-house dial manufacture in the Jura mountains. The gradient for the different colors is sprayed by hand. The REEF’s bold rehaut-style hour markers are also hand-applied and triangle shaped, pointing towards the broad hour and minute hands that share the same detailed beveled mirror polish and brushed top surface finishing. Hands and hour markers as well as a capsule on the bezel’s zero marker are deep-filled with Swiss Super-LumiNova® BGW9 that emits a long-lasting blue glow in dark conditions. Being able to read the time with absolute certainty is a matter of survival when diving.

Both the solid-link bracelet and the rubber strap feature a buckle with a patented fine-adjustment system as well as a completely re-engineered and patented quick release system that allows to swap straps without the use of any tools.

Unidirectional rotatable Ceramic bezel

The REEF’s unidirectional rotatable bezel is one of the key functionalities of the watch. Being one of the most exposed parts, the bezel is made of an extremely hard and scratch-resistant Zirconium oxide ceramic. The graduations and numbers are engraved by femto-laser pulsations. Each bezel takes 60 minutes of precision engraving to achieve its three-dimensional effect. Machined gear-like indentations on the bezel’s edge allow a diver the ideal grip to safely set and monitor diving time and decompression stops. The 60 click action is responsive and smooth, yet offers firm and precise function of the bezel.

officially certified movement

The REEF is powered by a Swiss Made Sellita SW300-1 self-winding movement with a power reserve of 42 hours. We've chosen its highest quality grade "Chronometer" because it comes with premium components such as a Glucydur balance wheel which is exceptionally hard and stable, very resistant to deformation, non-magnetic, and non-corrosive. Another reason why we've purposely chosen this thin movement is because it allowed to construct the REEF at just 11.4mm thickness and a perceived height of 9.4mm. The movement is completely decorated and wound by Formex’s in-house developed and custom built skeletonized rotor. Each one of these movements is certified by the COSC (the official Swiss Chronometer Testing Institute) and undergoes the meticulous 15-day rate test to ensure extraordinary levels of mechanical accuracy and precision. Each certified chronometer is unique, identified by a number engraved on its movement and a certificate number issued by the COSC. While less than 3% of Swiss watch movements are officially certified, Formex further rate test them per the same criteria after assembly, to measure if there is any deviation from the certification rates.

fine adjustment clasp

Besides contributing to visual appeal, the details on the REEF also serve a purpose. For a timepiece to be a watch for all occasions, it needs to feel exceptionally comfortable on the wrist. For even more wrist comfort, Formex added their patented Carbon Fiber Composite Folding Clasp that allows for fine-adjustment of the strap length on the go, allowing for a perfect fit on the wrist in all conditions and temperatures. The strap can be changed without the use of any tools with Formex's patented quick release system. The stainless steel bracelet with screwed links has the same quick release system and also features a unique fine-adjustment system.

meticulous attention to detail

Understated at first glance, but beneath the apparent simplicity lies exceptional craftsmanship in every respect. Take the symmetrical 42mm stainless steel case with its incredibly detailed finish on the ceramic bezel, perfectly rounded off with hand-finished mirror-polished bevels. The sunray finished dial is manufactured at Formex’s in-house dial manufacture in the Jura mountains. The gradient for the different colors is sprayed by hand. The REEF’s bold rehaut-style hour markers are also hand-applied and triangle shaped, pointing towards the broad hour and minute hands that share the same detailed beveled mirror polish and brushed top surface finishing. Hands and hour markers as well as a capsule on the bezel’s zero marker are deep-filled with Swiss Super-LumiNova® BGW9 that emits a long-lasting blue glow in dark conditions. Being able to read the time with absolute certainty is a matter of survival when diving.
