CITIZEN L —CITIZEN’s preeminent women’s watch brand renowned for fine jewelry-like elegance and beauty — has pursued approaches that incorporate sustainably produced and environmentally friendlier processes and materials in the lineup since 2016.

*Ethical commitment: See reference material at bottom

This new series in the CITIZEN L AMBILUNA*2 collection embodies the brand’s state of mind regarding sustainability and the future. The creative inspirations evolve from “Earth, Water, Fire, and Air” and the natural wonders that motivate our direction for the future. This inspiration comes from Greek philosopher Empedocles who named the elements the four “roots” from which all matter derives.

The new watch models incorporate lab-grown diamonds on the dial for the first time and uses Piñatex® materials made from recycled pineapple leaves for the band construction. What’s more, CITIZEN also introduces ECOPET® (polyester fiber) which utilizes recycled polyester fibers. The new material enhances the texture as well as comfort.

The case construction comprises CITIZEN’s unique material Super Titanium™*3, which is lightweight, gentle on skin and highly resistant to scratches. The case design is asymmetrical with lugs at the 12 o’clock and 6 o’clock positions. This unique design permits the watch to be easier to wear and prevents the face position from being displaced when worn.

CITIZEN L will continue to make endeavors toward newer sustainable manufacturing that emphasizes the importance to the environment, our global society, and people the world over.

[Product Feature]

A sustainably produced watch that exemplifies the beauty of Earth

Three models of the signature AMBILUNA lineup embody CITIZEN L’s commitment toward sustainable production. Inspired by “Earth, Water, Fire, and Air” elements these awe-inspiring designs showcase the natural beauty of the Earth by featuring materials that represent the appearance of the individual elements. A model inspired by "Water" will be announced in 2021.

Inspired by Earth

Imagined by the boldness, yet gentleness of the Earth which nurtures all life. The dial has an earthy brown gradation with bold lamé to express fresh rejuvenation of the land after rainfall. Lab-grown diamonds are placed at 12 o'clock. The strap uses Piñatex®- a sustainably produced material made from pineapple leaf. Even the texture of the fibers is carefully preserved, further expressing the intricacies of our Earth.

Inspired by Fire

The ethereal atmosphere of the sky is expressed by imagining a provocative sunrise as a color dye which splashes the sky with moments of color gradation and subtle shadows of mother of pearl on the white dial. A lab-grown diamond is positioned at 12 o'clock. The band uses ECOPET® — a sustainably produced material made from recycled plastic bottles.

Inspired by Air

Inspired by the rejuvenating breath of life-giving air, this model conveys the impression of transparent freshness. The dial changes color from blue to beige depending on the viewing angle, creating an organic-like atmosphere. A lab-grown diamond is positioned at 12 o'clock.
The band uses ECOPET® — a sustainably produced material made from recycled plastic bottles.

CITIZEN L uses environmentally friendly and sustainable materials for the first time

To conserve the beauty of the Earth now and for the future, CITIZEN adopts materials that have low impact on the environment.

- Uses lab-grown diamond on the dial
For the first time, CITIZEN utilizes a single lab-grown diamond that has low impact on the environment, at the 12 o’clock position.

Lab-grown diamond
Lab-grown diamonds have the same the chemical composition, hardness and brightness of naturally occurring diamonds. The advantages of lab-grown diamonds, however, are considerations to the environment, safety and labor practices in mining for them, and the peace of mind knowing these diamonds are lab-grown. CITIZEN L lab-grown diamonds are supplied by Swarovski, which is RJC (Responsible Jewelry Council) certified.

- Sustainable materials Piñatex® and ECOPET® are used in the band construction

*Adopted model: EG7072-19X
Often called "pineapple leather" Piñatex® is an alternative material to animal skin leather products, made entirely of discarded pineapple leaves and extracted fibers.
In addition, the by-product extracted from the fiber is used as a natural fertilizer and bio-fuel because of its rich nutrient content, and leaves no waste.

*Adopted model: EG7070-14A、EG7073-16Y
Recovered PET bottles are melted and recycled using material Recycling technology. The process reduces CO2 emissions as compared to petroleum as a raw material. The finished material characteristics are soft and resilient.

The use of Super Titanium™ - Asymmetrical case design for easy wear

The case is made from CITIZEN's proprietary titanium material Super Titanium™, which is lightweight, skin-friendly, and scratch-resistant. In order to maintain the face position from natural wear and keep it from shifting to the 12 o'clock position, the lug at the 12 o'clock is longer than the 6 o'clock (the part that connects the case and the band), while maintaining a smooth curve on the wearer’s wrist.

Light-powered "Eco-Drive" equipped

All CITIZEN L models feature Eco-Drive — a CITIZEN proprietary light-powered technology that converts solar and room light into electrical energy to power watches.
CITIZEN’s Eco-Drive can power watches for at least 6 months with a full charge and from power stored in a secondary battery, without the need to replace the batteries. This further reduces waste of battery disposal.

Since its founding in 1918, CITIZEN have held the belief of “Better Starts Now” — that is, no matter who you are and what you do, it is always possible to make something better, and now is the time to start doing it.

CITIZEN L’s ethical commitment. What we can do for the Earth, society and people.

1. Disclosure of materials

We want our customers to be able to wear our watches with complete peace of mind. This is why we are completely transparent about disclosing all the materials involved in their manufacture, including chemical materials (what and how much).

2. Disclosure of CO2 emissions (third-party verification, a watch industry first in Japan*)

The first step toward reducing your CO2 emissions is to analyze how much CO2 a product actually emits. This is why we calculate the total volume of greenhouse gases emitted during the product lifecycle — from procurement of materials and manufacturing to the life and eventual disposal of the watch. We present the result in easy-to-understand terms: “This watch equates to xx kilograms of CO2.”
* CFP Program certification of the Japan Environmental Management Association for Industry. Surveyed by CITIZEN in June, 2020.

3. Commitment to maintaining DRC Conflict-Free

The Democratic Republic of the Congo and neighboring countries(“DRC nations”) are reported and criticized internationally for inhumane actions by armed insurgents. Tantalum, tin, gold, and tungsten(“conflict minerals”) found in DRC nations are unfortunately becoming an important source of fund for such insurgents. Based on our firm belief that our production “must not cause unhappiness to any” and “there should be no sacrifice behind the beauty,” based on the Conflict Mineral Template Report submitted from the source, we make sure that all minerals used to make CITIZEN L watches are not sourced from “DRC nations” or “if they are from a DRC nation, it is supplied from CFS(Conflict Free Smelter).

4. Reduced-size user manual

We dramatically cut the amount paper we use by putting the watch’s nine-language instruction manual online. It also enables our customers to access the manual wherever they are. We can also take advantage of the web to provide the information in a more flexible, accessible format.

5. Sustainable packaging

From the perspective of “reuse,” we have considered packaging, and created an improved sustainable package for our watches.
