CITIZEN TSUYOSA Automatic Sky-Blue Dial and Stainless Steel

Product Overview

The CITIZEN Tsuyosa Automatic watch delivers a bold blend of modern sports design and refined elegance in a well-proportioned 40mm stainless steel case. Part of the NJ015 series, this timepiece is crafted for women who value both aesthetic appeal and mechanical precision. At its heart lies a self-winding automatic movement—Caliber 8210—that harnesses the natural motion of the wrist to power the watch, eliminating the need for battery replacements. The striking sky-blue sunray dial shifts subtly in tone under different lighting, offering a dynamic visual experience that stands out in any setting. Silver-tone hour markers, hands, and a minute track provide crisp contrast against the radiant blue background, while luminous accents ensure readability in dim conditions. A date window at the 3 o’clock position adds practical functionality without disrupting the clean design. The watch is protected by a scratch-resistant sapphire crystal with anti-reflective coating, enhancing both durability and clarity. An exhibition case back reveals the intricate inner workings of the automatic movement, celebrating the craftsmanship behind every tick. The integrated stainless steel bracelet maintains a seamless, contemporary look and fastens securely with a fold-over clasp and push-button release. With water resistance rated at 50 meters (5 bar), it’s suitable for everyday exposure to water, including handwashing and light swimming in still water. Whether worn at the office, during weekend outings, or for casual evenings, the Tsuyosa transitions effortlessly across settings, offering reliable performance and enduring style.

Key Features

• Automatic Movement (Caliber 8210): This mechanical movement operates without batteries, using an internal oscillating weight that winds the mainspring as you move your wrist. The 3-hand configuration tracks hours, minutes, and seconds with consistent accuracy. As a self-sustaining system, it appeals to those who appreciate traditional watchmaking and prefer not to rely on battery replacements.
• Sky-Blue Sunray Dial: The dial features a radiant sunburst finish in a vivid sky-blue hue that catches and reflects light beautifully. Silver-tone accents—including hour markers, hands, and a minute track—create sharp visual contrast. Luminous elements on the hands and markers allow for easy time reading in low-light environments. A date window at 3 o’clock adds everyday utility.
• Scratch-Resistant Sapphire Crystal: The crystal is made from synthetic sapphire, one of the hardest materials used in watchmaking. Its anti-reflective coating reduces glare, improving visibility in bright conditions while offering superior resistance to everyday scratches and impacts.
• Integrated Stainless Steel Bracelet: The bracelet is crafted from matching stainless steel and designed to flow seamlessly from the case, creating a unified, modern appearance. The fold-over clasp with push-button release ensures a secure and comfortable fit, making it easy to put on and take off.
• Exhibition Case Back: The transparent rear case offers a clear view of the automatic movement in action. This feature highlights the mechanical complexity and precision engineering that define the watch’s operation, appealing to enthusiasts of horological craftsmanship.
• Water Resistance up to 50 Meters (5 bar): Rated for 50 meters (166 feet), the watch can withstand splashes, rain, and brief immersion in still water. It is suitable for everyday activities like handwashing or light swimming but should not be used for snorkeling, diving, or high-impact water sports. The crown should not be operated while submerged.

Important Notes

While the watch is water-resistant to 50 meters, it is not intended for diving, snorkeling, or prolonged submersion. Avoid operating the crown or pressing buttons while in water. As with all mechanical watches, slight variations in timekeeping—such as gaining or losing a few seconds per day—are normal and depend on usage patterns and positioning. Regular servicing is recommended to maintain optimal performance of the automatic movement. The watch should be stored in a dry, safe place when not in use to preserve its condition. It arrives in original packaging measuring 4.65 x 3.78 x 3.07 inches and weighs 11.36 ounces.
