CITIZEN announces a limited-edition model commemorating
its 50th anniversary of titanium technology

CITIZEN celebrates its 50th anniversary this year of the release of the world's first titanium watch. In commemoration, the company announces the new SATELLITE WAVE GPS F950 — CITIZEN Titanium Technology 50th Anniversary Limited Model — a testament to its superior titanium processing technology.

Titanium Technology 50th Anniversary
Limited Model



Titanium was the favored construction material used in the Apollo spacecrafts in the 1960s due to its lightweight and rust-resistant properties. The material is also uniquely biocompatible and less likely to cause metal allergy reactions to the human body. CITIZEN quickly realized the potential of the material for a new generation of watches, and created the X-8 Chronometer model in 1970, which became the world’s first titanium watch. While titanium material offers many advantages in watch construction, the metal is prone to stick to the mold when subject to pressure of a hundred or more tons, resulting in deformation, and has a softer surface than stainless steel which is easily scratched. In 2000, CITIZEN overcame these challenges by developing Super Titanium*1 – its own surface treatment and titanium processing technologies that offered nearly five times the surface hardness of stainless steel and smooth, mirror-like finish.

Marking the 50th anniversary since the release of the world’s first titanium watch, CITIZEN proudly announces the 50th Anniversary Model of CITIZEN Titanium Technology as a culmination of titanium innovation.

This model inherits the “space" design concept of the "SATELLITE WAVE F100" released in 2014 and "SATELLITE WAVE GPS F900" in 2015, respectively, while making full use of CITIZEN's exclusive titanium-processing technologies to further advance innovation. The case and band feature pronounced three-dimensional surfaces with edgy, straight lines that create a symmetrical profile shape of angles and shadows. The black dial comprises a multi-layered structure with six parts stacked on top of one another, evoking the image of the endless depths of outer space. The case conveys a sense of refinement by combining two parts from CITIZEN's unique surface hardening technology, "Duratect*2 DLC" and "Duratect Sakura Pink”.

Caliber F950 is featured in this top-of-the-line movement Eco-Drive GPS SATELLITE WAVE*3. With reception of exclusive time signal, this advanced movement has the ability to receive GPS satellite signals at the world's fastest speed of within 3 seconds, and offers remarkably fast watch hand movements through a high-speed twin-coil motor that’s capable of rotating the second hand 360° forward or reverse in a single second. This unprecedented speed streamlines the process from reception to completion seamlessly.

[Main features]

"Space" design theme

The new model utilizes SuperTitanium, which is the same material that will be used in Japan’s lunar exploration project, “HAKUTO-R*4". While inheriting the design concept "Space" from the 2014 SATELLITE WAVE F100 and the 2015 SATELLITE WAVE GPS F900, the new design idea is further advanced through the use of CITIZEN’s proprietary titanium processing technologies to create a multi-layer, six-part stacked dial that envisions the depth of the endless universe.

Edgy, linear design lines for case and band

Centering on CITIZEN’s titanium-processing technology cultivated and advanced over decades, the case and band feature edgy, straight lines that form a three-dimensional surface, creating a stunning sculpted shape of angles and shadows.

Cohesive color combination inspired by Duratect

Representing the 50th anniversary of the world’s first titanium watch, the new F950 model features a combination of Duratect DLC and Sakura Pink that produces a cultivated finish. The dual-case structure is the result of precision processing technologies developed over decades of innovation.

[History of titanium watches]

1970 - World’s first titanium wristwatch released
X-8 chronometer

The world's first titanium watch used titanium with a purity of 99.6% for the case. The “X-8” product name comes from a combination of “x” signifying the “unknown” and “8”, the infinite symbol of “∞” turned sideways to portray infinite possibilities of titanium.

1987 New technology development with soft brilliance
ATTESA first model released

The first model "ATTESA" elevated the texture of titanium to a new level. Known to be difficult to polish to a mirror-like shine, titanium metal is normally used for outdoor watches for a rough, matte surface texture look. ATTESA is the first genuine business watch to introduce the new surface treatment process that creates a refined, polished look with a beautiful luster. It is also hypo-allergic.

2000 Birth of Super Titanium
ASPEC World Time

The first model to use Super Titanium, which utilizes CITIZEN's proprietary surface-hardening technology “Duratect”.

2006 First model to adopt dual-surface hardening technology "Duratect MRK + DLC"
Promaster Eco-Drive radio-controlled watch

This is the first model to adopt "Duratect MRK + DLC", which is made by applying "Duratect MRK" to harden the surface of the material itself and then overlaying "Duratect DLC" to coat the surface with low-temperature plasma technology. This combination results in reinforced durability that’s highly resistant to scratches. It is also hypo-allergic.

2018: Super-thin 3.53 mm model using Super Titanium
Eco-Drive One

This model features Eco-Drive — CITIZEN’s light-powered technology with the world’s thinnest movement of only 1.00 mm thickness — housed in a Super Titanium case just 3.53 mm in total. Despite being ultra-thin, Super Titanium achieves remarkable durability and robustness required for watches.

[SuperTitanium characteristics]

Super Titanium is the amalgamation of CITIZEN's original titanium-processing and Duratect surface-hardening technology.

1. Resistant to scratches

Five times the hardness of stainless steel, Super Titanium is highly resistant to scratches that may occur during daily wear, and continues to retain its original brilliant luster even after 10 years of usage.

2. Lightweight

Weighing only 60% of stainless steel, the material is surprisingly lightweight and feels like a part of your body, allowing you to wear it all day long without fatigue or stress.

3. Gentle on the skin

Titanium is a metal-allergy-resistant material that is gentle on the skin. By applying proprietary surface-hardening technologies instead of traditional metal-coating technologies, all of titanium’s inherent positive qualities are brought to life.

4. Rust-resistant

Super Titanium will not rust from contact with fresh water, seawater, or sweat. Since there is no worry about rust or loss of its natural shine, outdoor enthusiasts and wearers who work with water can use it with peace of mind.

5. Rich color variations

Unlike untreated titanium, Super Titanium enables the creation of a wide variety of color tones such as silver, black, gold, and even pink gold. The design possibilities for watches are now virtually infinite.
