Technical Information

The Essence Watch Company is an innovative designer of watches and the known leader in scratch-resistant technology.

What metal is tungsten?

Tungsten, also known as a “wolfram”, was discovered in 1781 by Carl Wilhelm Scheele, a Swedish pharmacist. In 1783, two Spanish chemists, brothers Don Fausto, and Don Juan del Huyar, extracted the pure metal from another mineral, wolframite. The resultant pure tungsten is a steel-gray to tin-white metal with the highest melting point (at 3,422 °C, 6,122 °F) and lowest vapor pressure of all metals, and with the highest tensile strength.

How hard is tungsten - how scratch-resistant?

The hardness of tungsten makes it the most scratch-resistant of metals, and a perfect material for use in watch making. Due to its extreme hardness, however, tungsten oxidizes in air and must be protected at elevated temperatures. But it has excellent corrosion resistance and is attacked only very slightly by most mineral acids.

High-Tech Ceramic

High-tech ceramic refers to materials made of nonmetallic minerals that have been permanently hardened by firing at a high temperature, or objects made of such materials. High-tech ceramic uses silicon carbide, alumina, and other specially purified or synthetic raw materials. This material is highly valued for its scratch resistance, durability, light weight, and smooth touch. High-tech ceramic is highly suitable in watch making.

High-Tech Ceramics - at the Cutting Edge of Technology

The oldest known fired ceramics date from the Paleolithic period some 27,000 years ago. Today’s high-tech ceramics, however, are more advanced than pottery. These materials are at the cutting edge of innovative technology. From artificial joints and medical devices to system components for the space industry – from packages for super speed chips to printer drums for page printers, to cutting tools – whenever metals have reached their limit, that’s when innovative ceramics are needed.

The Major Advantages of High-Tech Ceramics

  • Extreme hardness and high resistance to wear:
    High-tech ceramics are considerably harder than metals – only diamonds, in Mohs scale, are harder.
  • High resistance to heat:
    High-tech ceramics are resistant to high temperatures and may be used at temperatures as high as 3,272 °C.
  • High resistance to corrosion:
    High-tech ceramics do not react to acid, alkali, or basic substances.
  • High isolation properties against heat and cold

The application of ceramic coatings required a high level of technical skill and specialized equipment.

Scratch-Resistant Sapphire Crystal

The raw material Essence uses in its manufacture of scratch-resistant sapphire crystals is a chemically pure form of aluminum oxide. This material crystallizes at 2,500 °C into a sapphire nugget, which is afterwards cut, calibrated, and faceted with specialized diamond tools. The result is a highly resistant and enduring “shield” that protects Essence watches from scratching. The cut of the Essence sapphire crystals may be flat, domed, or star shaped.

How hard is hard?

The scratch-resistant materials used by Essence are highly resistant to scratches, dings, and other abuse, but they are not indestructible. Hard knocks or dropping the watch should absolutely be avoided. Furthermore, please be aware that some everyday materials your watch may come into contact with may contain particles of close-to-diamond hardness. Such materials can be found, for instance, in sandpaper, nail files, granite surfaces, grind stones, and concrete walls. You should therefore avoid the contact of your watch with such objects or surfaces.

Skin Friendliness

In addition to its achievements in the field of design and scratch resistance, Essence also takes a leading position in wearer comfort and skin friendliness. This role is based essentially on its use of the following important elements:

  • High-tech ceramics or tungsten, used instead of brass and steel, in the watch cases and bracelets: these materials are known not only for their scratch resistance, but also for their biocompatibility and skin friendliness.
  • High-tech ceramics or surgical stainless steel (316L), used in the case backs and bracelet clasp and buckles: such materials guarantee perfect skin friendliness

Swiss Precision

The name Essence guarantees a quality Swiss watch movement of greatest precision. Every single movement undergoes numerous controls before being installed into an Essence watch. In its quartz watches, Essence uses Swiss ETA, ISA, or Ronda movements, which it equips with top-quality Swiss batteries. Run under normal conditions, the life cycle of such batteries is between 24 and 30 months. A fully wound Essence automatic watch has a power reserve of at least 36 hours.

Water Resistant

Engraved on the case back of each Essence watch is the word “water resistant”. This means that the Essence watch can withstand water pressure up to a depth of 30 meters (100 feet).


Essence bracelets are designed to be elegant, durable, and easy to adjust.

Pro Tips

Before "sizing" a bracelet, estimate the number of the links you’ll want to remove.

  • If you are only making a small adjustment, check to see if it can be made by adjusting the clasp mechanism before you start removing links.
  • Work on a flat surface so that the links stay aligned.
  • On clasp bracelets, take care to remove an equal number of links from each side of the clasp.
  • Save any links you remove.

Note: On ceramic or tungsten links, take care to use a push-pin that is at least 0.02 mm. smaller than the actual hole of the link; otherwise, you may actually damage the link.

Screw-Pin Bracelets

Screw-pin bracelets are easy to size. Unscrew the pins that hold the links you wish to remove, then remove those links, reassemble the band, and re-insert a screw to hold it together.

Note: In some bracelets, not all links have accessible screws.


  • The operational temperature range is between -5 C -45 C, with a monthly error that does not exceed +/- 15 seconds.
  • A secondary function allows you to set the time: hour, minute, second, and day/date.
  • The watch uses a 1.55 V oxidized silver battery.

Time Setting

  • How to set the time in watches without a day/date function:
    1. Pull the crown out to 2 when the second hand is on 12 o’clock; this will stop the second hand.
    2. Adjust the time by turning the crown to the desired time.
    3. Push the crown back to 1; this will start the second hand moving again.

  • How to set the time in watches with a day/date function:
    1. Pull the crown out to 3 when the second hand is on 12 o’clock; this will stop the second hand.
    2. Adjust the time by turning the crown to the desired time.
    3. Push the crown back to 1; this will start the second hand moving again.

  •  How to set the day/date function:
    1. Pull the crown out to 2 (the second hand keeps moving).
    2. To set the date, turn the crown clockwise; to set the day, turn the crown anticlockwise.
    3. Push the crown back to 1.

Note: Avoid setting the day/date function between 9:30 p.m. and 3:30 a.m. since the gear of day/date function operates at this time.
