Citizen is known as a watch manufacturer that has developed a wealth of unique technologies.

In particular, The Citizen, the brand's flagship model, offers up to 10 years of free warranty and inspections upon registration in the owners club after purchase, allowing you to enjoy your watch for a long time.
The selection is also extremely diverse. In addition to "The Citizen," there are many collections in the lineup that will satisfy men's intellectual curiosity and sense of fun, from the "Citizen Attesa" that supports active business scenes to the highly original "Campanola."
Whether you want to use your watch as a reliable tool, or enjoy the passage of time with a playful touch expressed through superior technology, Citizen watches will meet the diverse needs of experienced men in their 40s.
The Citizen "30th Anniversary Limited Edition Model: High-Precision Eco-Drive with ±5 Seconds Annual Accuracy" Ref. AQ4100-65M
The Citizen, the flagship line of the brand, will celebrate its 30th anniversary in 2025. To commemorate this milestone, a number of limited edition models have been released, including the Ref. AQ4100-65M. This special model, limited to 550 pieces, features a dial made of indigo-dyed washi paper in the traditional Japanese color of "kachiiro."

Light-powered quartz movement (Cal. A060). Super Titanium™ case (diameter 38.3mm, thickness 12.2mm). Water resistant to 10 bar. Limited to 550 pieces worldwide. Price: 451,000 yen (tax included).
The indigo-dyed Japanese paper used in this watch is made by artisans who hand-dye each sheet of Tosa washi paper in the color of Kachiiro, using the traditional indigo dyeing technique of "natural lye fermentation." This shade is considered the deepest of all indigo shades, and due to its auspicious name, it has long been prized for weapons and celebratory items. On the dial of this watch, the unique fibers of the washi paper enhance the depth and brilliance of this color, while at the same time allowing light to pass through to the solar cell as part of the Eco-Drive system.
The case and bracelet are crafted from Super Titanium™. The case measures 38.3mm in diameter and is water resistant to 10 bar, while also boasting lightweight, scratch-resistant, and hypoallergenic qualities.

The dial of this watch is made of Unryu paper, which features a unique pattern created by long fibers.

The fibers, which also resemble soft, fluttering clouds, further enhance the richness of the look.
The dial features Sakura Pink colored hands and indexes and is housed in a Super Titanium™ case that uses Duratect Sakura Pink. The strap is made of chic brown alligator leather produced by an environmentally friendly LWG-certified tanner, giving the entire watch a unified and elegant finish.
Like the aforementioned Ref. AQ4100-65M, this movement is the Cal. A060.

Citizen Attesa "ACT Line Black Titanium™ Series" Ref. CC4055-65E
Citizen Attesa is a titanium watch brand that generously incorporates Citizen's cutting-edge technology. Among them, the Ref. CC4055-65E, part of the "ACT Line" series, is a model equipped with a top-of-the-line movement that not only features Eco-Drive but also GPS satellite wave timekeeping.

Campanola "25th Anniversary Limited Edition Cosmosign" Ref.AO4010-51M
Campanola, which expresses a unique worldview, has selected a special "Cosmosign" to commemorate the brand's 25th anniversary. This is a limited edition model of 250 pieces, with the theme of "a night sky illuminated by the moon."

Quartz movement. Stainless steel case (45mm diameter, 14.1mm thick). Water resistant for everyday use. Limited to 250 pieces worldwide. Price: 418,000 yen (tax included).
What makes this watch special is its gorgeous blue-based coloring. The dial flange is colored royal blue like the night sky, and the Roman indexes and hands are gold, reminiscent of moonlight, creating a striking contrast between the blue and gold.
The dial of this piece also features a mechanism that rotates in the opposite direction to the hands, allowing it to function as a star chart that allows you to see the starry sky in real time. 1027 stars of magnitude 4.8 or higher and 166 nebulae and star clusters are faithfully reproduced using a precision printing technique that involves layering 14 plates, displaying the entire sky at 35 degrees north latitude.
The case, covered by a three-dimensional dual spherical sapphire crystal, has a thick bezel and is polished all over. The case is large at 45mm in diameter, but the curved middle case ensures a comfortable fit on the wrist.
