Citizen has always strived to innovate. When it comes to the materials we use we take the same approach.
In 1970, we launched the world’s first watch using solid titanium that is light-weight, hypo-allergenic and resistant to rusting.
By treating CITIZEN’s proprietary surface hardening technology, Duratect, to crafted solid titanium, we created Super Titanium™.
Achieving more than 5 times the hardness of stainless steel and providing better wearing comforts, Super Titanium™ represents CITIZEN’s pursuits for bringing something better to people’s life.
Features of Super Titanium
Harder Materials, Less Scratches
Keeping your watch scratch free and undamaged doesn’t mean you have to hide it away in your dresser. Super Titanium™ provides the ideal solution to the beauty vs. preservation dilemma.
Thanks to CITIZEN’s proprietary surface hardening technology, Duratect, Super Titanium™ makes your watch incredibly resistant to daily wear and tear.
Light, for better comfort
Super Titanium™ is approximately 40% lighter than stainless steel.
So light that you might forget you are wearing a watch.
Appreciate better comfort on your wrist, whatever you may do.
A gentle metal that’s kinder on your skin.
Super Titanium™ reduces the risk of adverse skin reaction to metals thanks to the use of hypoallergenic solid titanium and CITIZEN’s proprietary surface hardening technology.
Even people with sensitive skin do not have to be concerned about skin irritation when wearing CITIZEN Super Titanium™ watches.
Note: Super Titanium™ does not prevent reaction to all metal allergies.
More resistant to corrosion, for lasting beauty
Super Titanium™ is more resistant to corrosion including when coming in contact with salt water.
Wherever you are and whatever you do, you can rely on Super Titanium™ to ensure your watch looks it’s best.

Titanium is the fourth most abundant structural metal on Earth. An incredible material that does not react to sunlight, salt water, or any body chemistry, it reduces the potential of metal allergic reaction and is corrosion resistant.
In its natural state, titanium is very soft making it extremely difficult to process solid titanium for the purposes of watch manufacturing. CITIZEN designed and improved upon their own techniques to overcome these challenges.
Along the way we discovered a diverse range of advanced processing techniques. The process can be divided into 3 steps.
Titanium is an active metal that reacts easily with oxygen, carbon, nitrogen and other elements. When forging, the titanium atoms easily adhere to the metal molds used in pressing and start fusing into the mold, making it difficult to reshape. In order to prevent the adhesive bonding of titanium we change its qualities; heating it to a high temperature before pressing, considerably lessening it’s resistance to shaping. This discovery lends itself to numerous pressing possibilities.
Because it reacts easily to oxygen in the air, the filings from titanium stick to the edge of the drill and cause friction when drilling. This results in reducing the thickness of the drill and inaccuracy in the holes being cut. CITIZEN refined traditional cutting techniques for stable titanium processing though rigorous trial and error of numerous cooling oils, lubricants and cutting speeds.
Polishing presents another hurdle when using titanium in watches. The conventional polishing process creates irregularities on the surface that would mar a watch’s sheen, owing to slight variations in the hardness of the crystal grains that form titanium. At CITIZEN we combine a number of polishing techniques, including barrel and Sallaz polishing, to realize better surface quality of Super Titanium™ watches.
Duratect Surface Hardening Technologies
CITIZEN’s proprietary technology, Duratect, was developeded to harden the surface of watch materials.
Machinery for Duratect treatment
CITIZEN has various ways for surface harfening.
It provies a range to surface hardness (up to more than five times the surface hardness of stainless steel) while at the same time, colouring the watches in silver, black, and gold, which were once thought impossible.

The First Titanium Watch
Super Titanium™ technology dates back to the 1960s. The Apollo moon mission showed the potential of titanium as a material for commercial products. With this first glimpse at the metal’s potential, CITIZEN engineers began to apply their knowledge into exploring the possibilities of incorporating titanium into watch manufacturing.
In 1970, we produced the world’s first watch with a solid titanium case. Named the “X-8 Chronometer”, it expressed the high expectations of titanium, a material with infinite possibilities.
The World’s First Watch with Solid Titanium Case
Titanium Watches for Everyone
The Full Titanium-Made
CITIZEN was so impressed with titanium’s hypoallergenic properties that we made it our mission to create innovative watches that were also safe and gentle; delivering the satisfaction of wearing a watch to everyone.
With the Attesa’s launch in 1987 we introduced the first full titanium-made hypoallergenic watch created in-house.
Super TitaniumTM, a CITIZEN original
Our challenge started with the concept of making watches using a material with infinite possibilities. We met that challenge by first creating our own titanium processing technology and following that up with our proprietary surface hardening technology, Duratect. But the challenge continues as we look forward to new discoveries. Better Starts Now.
By improving our titanium-processing technology, we make it possible for our designers to deliver a wide range of great designs. Advances in our surface hardening technology has also allowed CITIZEN to create watch models with higher resistance to scratches in a wide range of colors with stronger hypoallergenic properties.
Our goal is to provide everyone, everywhere with the chance to comfortably wear a beautifully designed watch. It is this ambition that drives our team at CITIZEN to face any and all challenges a head.
