Product Description

Inspired by the beautiful oceans that unite the world, the watches of Citizen's UNITE with BLUE series join the colors of the seven seas on one 100% recycled polycarbonate dial. This example, which comes as part of the technology-driven Attesa collection, marks a unique take on the elevated luxury sports style. A 42.5mm scratch-resistant Super Titanium™ case in black DLC and a matching integrated leather strap solidify the lightweight, durable construction of the timepiece. On the special UNITE with BLUE iridescent dial, flowing hues of azures and greens meld into each other for a captivating aesthetic of sustainable style, while upon it, a time-and-date display is at work, with silver-tone accents adding dimension. Advanced features of the timepiece include world time in 26 time zones and a perpetual calendar. Featuring our sustainably light-powered Eco-Drive Atomic Timekeeping functionality, the timepiece self-adjusts to time or calendar when traveling overseas by receiving local time signals in four different regions. Water resistant up to 100 meters. Caliber H145.

This style is part of the UNITE with BLUE collection, which highlights Citizen’s commitment to sustainability including a Promaster Dive model and CITIZEN L Bianca style. Sustainably powered by the brand’s proprietary Eco-Drive*1 technology, both timepieces feature a structural color dial*2, inspired by the oceans that unite the world.

Stunning Elegance

I have purchased three Attesa models, all are amazing timepieces. The titanium case is extremely lightweight; the watch floats on your wrist. The color changing face is gorgeous and creates eye-catching interest; every change of the viewing angle throws off a mesmerizing swirl of blues and greens. Attesa is the convergence of art and function.

Highly recommend.

Love the watch. Beautiful design, lightweight, and no trouble synchronizing on the east cost.

Beautiful and Functional

I bought an ecodrive watch 20 years ago, and while I was skeptical about a light powered watch at the time, it never once stopped, (in fact it's still running, dang thing just wont' quit) so it was a foregone conclusion that I'd replace it with another Citizen Ecodrive. I've had the watch for about a month and have been absolutely delighted! It's a beautiful time piece and I can't keep my eyes off it. Functionally the perpetual calendar worked as advertised and when we went from November 30th to December 1st I didn't have to touch it. The atomic timekeeping is accurate to the second, I know this because I've check it with an alexa device on several occasions. The only slight criticism I have is that I wish it would have been available with a titanium band. For me, whether its belts of watch bands, leather is either too tight or too loose, that being said, I'm extremely happy with my purchase and would highly recommend this time piece.

I have had some really nice watches, and still do, but this is far and above the best. It has an amazing backstory from recycled dial - painting, to the sleep mode enabling years of battery when not in use. Did I mention sexy? It is a really good looking watch, very smooth in appearance and operation.
