A sustainably manufactured watch inspired by the natural beauty of Earth
New model themed on “water”
Band composed of fibers from recycled marine plastic

With its sustainably produced line of women’s watches, CITIZEN L has championed the effort to manufacture sustainable watches that prioritize the preservation of our global environment and societies of people worldwide. The first in the CITIZEN brand lines to adopt synthetically lab-grown diamonds, CITIZEN L uses these to express the natural beauty of Earth elements for the AMBILUNA*1 collection. This collection of women’s watches features a new model inspired by “water” and two other models influenced by mineral elements.

Price and release date are to be determined.

Since 2016, CITIZEN L’s core identity has been about manufacturing sustainable watches of ex-quisite designs. With Earth’s feminine beauty as our inspiration, CITIZEN L has showcased sus-tainable manufacturing of timepieces that demonstrate its deep-rooted commitment toward the environment, people and society.

All models feature the innovative Eco-Drive*2 system utilizing light to power watches and does not require periodic battery replacement. What’s more, sustainably produced materials adopted in the construction support environmental initiatives without sacrifice to utility.
*Ethical commitment: see reference material below. at bottom

This new CITIZEN L model is incorporated into CITIZEN L’s signature “AMBILUNA collection”. In-spired by “water” — one of four natural elements*3 that make up all things — the new model philosophically completes the connection of the Earth to our future. The current models intro-duced in 2020 were inspired by the three elements: “Earth, Fire and Air.”

Further, two limited-edition models influenced by “minerals” will be included in the AMBILUNA collection. Drawing on the organic transformations of mineral elements over Earth’s long geo-logical evolution, these new models incorporate many stunningly unique colors and patterns.

CITIZEN L continues to pursue sustainable manufacturing that emphasizes the importance to the environment, our global society and people the world-over.

[Product Features]

Sustainably manufactured watches representing the natural beauty of the Earth

From the signature AMBILUNA collection that embodies CITIZEN L’s commitment toward sustain-able manufacturing, this new model inspired by “water” joins and completes the three 2020 models influenced by “Earth, Fire and Air,” respectively. The color scheme is based on “water,” which symbolizes the source of life, with the dial colors expressing the graduation effect of light hitting the seabed from bright blue at 12 o’clock to darker blue hues at the 6 o’clock position.

Employs sustainable materials that are environmentally friendly

CITIZEN L utilizes materials that have a low environmental impact in order to help preserve the natural beauty and mysteries of the Earth for the future.

-Band components use fibers extracted from beach-collected PET bottles
 To help protect our irreplaceable marine environment

Created in cooperation with “UpDRIFT*4”, an initiative driven by JEPLAN,INC and TOYOSHIMA & Co.,Ltd. to tackle with the issues of litter on beaches and rivers, textile fibers made from col-lected plastic bottles and other materials are used in the band construction. The new band textile is finished with a dark navy satin “Nashiji-ori” weave which gives it a unique texture feel that ideally suits the elegant world of Citizen L. The band is also supple and comfortable to wear, yet maintains the same durability characteristics of regular synthetic leather.

-Features synthetic lab-grown diamond on the dial

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 chemical composition, hardness and brightness of natu-rally occurring diamonds. The advantages of lab-grown diamonds, however, are considera-tions to the environment, safety and labor practices in mining for them, and the peace of mind knowing synthetic diamonds are grown in controlled laboratories. CITIZEN L lab-grown dia-monds are supplied by Swarovski, which is RJC (Responsible Jewelry Council) certified.

Case constructed of Super Titanium™*5

Asymmetrical lug design prevents wear misalignment.

Asymmetric design for ease of use
The case is made of "Super Titanium™,” CITIZEN’s proprietary titanium material that is light, gen-tle to the skin, and scratch resistant. In order to prevent the face from shifting toward the 12 o'clock position, the lugs at 12 o'clock and 6 o'clock (connecting the case and band) are asym-metrically shaped with the width at the 12 o'clock side, and are smoothly curved to follow the wrist.

Powered by “Eco-Drive” light power

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, all without the need for periodic battery replacement and thus reducing the amount of discarded batteries.

  • *1: AMBILUNA: Iconic collection in the CITIZEN L brand. The prefix “ambi” is a reference to the ambient environment of light and wind, and ambiguity which suggests the natural, mysterious changes that occur in nature. This is combined with “luna” in reference to the influences of the moon.
  • *2: Eco-Drive is CITIZEN’s proprietary technology that powers watches using any natural or artificial light source, eliminating the need to replace batteries. Certified as an Eco Mark product for the first time in the watch industry.
  • *3: The Four Elements: This is based on the concept of the Four Elements, which states that the world is composed of four naturally occurring elements: Earth, Water, Fire, and Air. The concept of the "four elements" is said to have originated in ancient Greece.
  • *4. UpDRIFT™: An initiative to recycle PET bottles and other materials collected through river and beach cleanup activities and recycle them as resources and products with less environmental impact.
  • *5: Super Titanium™ is CITIZEN’s proprietary technology to treat solid titanium with surface hardening technology. It is at least 5 times harder than stainless steel. In the 50 years since CITIZEN introduced the world’s first titanium watch, Super Titanium™ continued to evolve. It is highly resistant to scratches, light-weight and gentle to the skin for excellent wearing comfort. (Vickers hardness of stainless steel is about 200 Hv).
  • *6: Duratect is Citizen's proprietary surface-hardening technology. Duratect is a general term for a technology that increases the hardness of metal surfaces such as stainless steel and titanium, protects the watch body from scratches and small abrasions with excellent wear resistance, and maintains the brilliance of the material for long periods of time. Treating platinum with this process — a soft precious metal with a Vickers hardness of 50-110Hv — succeeds in increas-ing the hardness to 1,000Hv. In addition to strengthening hardness, the treated platinum is characterized by a bright, transparent-like color, which makes the watch shine even more brilliantly. (Vickers hardness of stainless steel is about 200Hv). Duratect DLC achieves Vickers hardness of 1,000-1,400 by creating an amorphous carbon hard film—mainly composed of carbon and hydrogen—on the surface of the material.
  • *7: Piñatex®: Often called "pineapple leather,” this alternative material to animal skin leather products is 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 due of its rich nutrient content, and leaves no waste.
  • *8: ECOPET®: Polyester fiber regenerated by recycling technology using collected PET bottles and other discarded materials. Compared to petroleum-based products, ECOPET results in reduced CO2 emissions, and offers flexible, soft material properties.
