New “Sea of Silence” models - UNITE with BLUE collection
CITIZEN Watch is releasing limited-edition models from a new themed collection, UNITE with BLUE, featuring structural colour dials with shades of deep blue inspired by the calm, glittering blue sea.
UNITE with BLUE Limited-Edition models
Experience the deep, calm blue of the UNITE with BLUE collection. Inspired by the concept of a “Sea of Silence,” the structural colour dials produce subtle color changes in response to light reflecting off the surface.
The pigment-free ink on the dial utilizes light reflecting off the surface of the microstructures in the ink to create a range of hues and tones. These unique dials were made possible thanks to Eco-Drive*2 technology that utilizes light as a form of clean energy to measure the passage of time. Four new models being released from CITIZEN ATTESA, CITIZEN PROMASTER, and CITIZEN Collection utilize different dial designs and processing techniques to create their own unique expressions of the ever-changing moods of the sea. Two new models from CITIZEN xC and CITIZEN L also feature diamonds representing air bubbles rising up from depths of the sea. The xC model uses lab-grown diamonds*3.

※1 Structural colour dial: A dial printed with pigment-free ink that produces colours by using light reflecting off the surface of the microstructures in the the ink layer.
※2 Eco-Drive is CITIZEN’s proprietary technology that powers watches using any natural or artificial light source, eliminating the need to replace batteries. A first within the watch industry, Eco-Drive was certified as an Eco Mark product by the Japan Environment Association (JEA) and recognized for its contribution to environmental sustainability.
※3 Lab-grown diamonds: Diamonds created in a lab that have the same hardness and brilliance as natural diamonds. All lab-grown diamonds used by CITIZEN are made in a lab, rather than being mined from the earth, making them ethical products created in adherence with the highest level of environmental, safety, and labor standards.
※4 GPS satellite-synchronized watches receive date and time signals sent by GPS satellites from space — orbiting 20,000
※5 Radio-controlled watches receive signals from radio transmitters to correct the time and calendar automatically.
※6 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, resistant to scratches, lightweight and gentle to the skin for comfortable wearing.
※7 Duratect is CITIZEN’s proprietary surface hardening technology that enhances the surface hardness of metals such as stainless steel and titanium, protecting watch bodies from scratches and damage. This technology offers excellent abrasion quality and maintains the luster of metals for long periods of time.
Platinum is a soft precious metal with Vickers hardness of 50-100 HV. CITIZEN’s proprietary surface hardening technology boosts this figure to 1,000-1,200 Hv. This treatment provides superior hardness as well as a bright, almost transparent, silver sheen to produce remarkably beautiful timepieces. (Vickers hardness of stainless steel is approx. 200 Hv).
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.

※8 Light-level Indicator detects and displays the intensity of light striking the dial (which generates the electricity to run the watch) in seven levels, allowing wearers to easily gauge the charge level in any given situation.
※9 Perpetual calendar is a fully automatic calendar control function that automatically adjusts the end of each month, including the months of a leap year, until February 28, 2100.
※10 BENEBiOL™: A biomass-based raw material for polyurethane(polycarbonatediol) developed by Mitsubishi Chemical Corporation. This material is contained in our watch straps as a raw material to achieve better durability and environmental friendliness
