ABOUT THIS WATCH

This very Special Edition of our best-selling Essence 39 mm Chronometer features a captivating dial made from a natural stone called “Eisenkiesel”. Eisenkiesel translates from German to “iron pebble,” referencing the numerous iron compounds found in the mineral and that form the recognizable vein pattern. Since the textures are organic, each single dial is a completely unique piece. It comes with the Essence tested and proven features, such as the patented Case Suspension System, a highly precise COSC-certified Swiss Automatic movement and our in-house developed deployant clasp with a unique fine-adjustment system that perfectly adapts to the wrist’s ever changing size due to heat and humidity.


Movement


The Essence ThirtyNine is powered by Sellita's highest quality grade SW200-1 Swiss Made Automatic movement, beautifully decorated and wound by Formex's custom skeletonized rotor. Each one of these movements is certified by the COSC and undergoes the meticulous 15-day rate test to ensure extraordinary levels of mechanical accuracy and precision.


Dial


Eisenkiesel is a quartz, and the stone used by Formex appears black with chocolatey brown iron inclusions. The production of this particular stone dial has proven extremely challenging, as the dial basis have to be cut in slices, making it incredibly fragile and brittle. The result is a fascinating dial, each with its unique pattern of interveined iron inclusions. Applied indices, deep-filled with Super-LumiNova® BGW9 and mirror-polished bevels provide legibility day and night.


Straps and Clasps


For a perfect fit and more comfort on the wrist at all times, we're using the new Formex Deployant clasp with a gradual fine-adjustment system for the leather and rubber straps. The stainless steel bracelet, which reflects the same flawless finishing of the Essence's case, has a hidden Micro-Extension. All straps and the steel bracelet can be changed without the use of any tools and in just a few seconds.

FEATURES

An Automatic, also called self-winding watch, is a mechanical watch in which the mainspring is wound automatically as a result of the natural motion of the wearer's arm, to provide energy to run the watch, making manual winding unnecessary. All our Automatic movements are manufactured in Switzerland.

A chronometer is a watch that has been tested and certified to meet the most strict precision and accuracy standards. “Chronometer” isn’t just a name that any watch brand can print on the dial of its watches. It is an official nomenclature, defined by precise rules, which lay down the definition of the term “chronometer”, describing the categories, the test programme and the acceptable minimum requirements for wrist chronometers. In Switzerland, the COSC, or Contrôle Officiel Suisse des Chronomètres, is the only official organisation allowed to certify chronometers.

Modeled with high-performance bikes and racing cars in mind, Formex’s patented Case Suspension System works by integrating four springs between the upper and lower watch case. The result is the ultimate shock absorption system designed to protect the watch movement and deliver unparalleled comfort to the wearer.
This watch features an ultra-strong and light-weight folding clasp, made of carbon fiber composite and a stainless steel or titanium buckle. The gradual fine adjustment system allows you to tighten or loosen the strap length when the wrist size varies due to temperature and activity.
All straps and bracelets can be interchanged by hand without the use of any tools and in a few mere seconds. This allows you to easily swap straps on the go and wear your personal style for any occasion.
A sapphire crystal or “glass” is a very hard, transparent material made of crystallizing pure aluminium oxide at extremely high temperatures. Sapphire is one of the hardest substances on earth. It measures 9 on the Mohs scale (diamond measures 10, the highest rating), which is a system for rating the relative hardness of various materials, making it virtually scratch proof.
Applying AR coating will limit the reflection on a sapphire or mineral glass to a very low level.
The transparent case back, made of sapphire crystal, makes it possible to see the movement inside the watch.
Water resistance measures how much water pressure a watch can handle before it breaks. This measurement is important to know for the proper care and keeping of your watch. Water resistance of 100 m / 330 ft means that it can be used for swimming, snorkeling, and similar activities.

39 mm Stainless Steel Case

The ThirtyNine might be smaller in dimension, but comes with the same detailed finishing as the original Essence. The brush finish on both case and bezel are perfectly rounded off with hand-finished mirror polished bevels. With a height of just 10mm, this watch will fit under your shirt cuff as well as your wing suit...

officially certified movement

The Essence ThirtyNine is powered by a Swiss Made Sellita SW200-1 self-winding movement with a power reserve of 41 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. 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 Essence ThirtyNine 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 micro-extension system.

THE EISENKIESEL DIAL

This Limited Edition watch features a captivating dial made from a natural stone called “Eisenkiesel”. Eisenkiesel translates from German to “iron pebble,” referencing the numerous iron compounds found in the mineral and that form the recognizable vein pattern.
