The Citizen Tsuyosa automatic watch features a 40 mm stainless steel case with a striking sunburst blue dial that creates dynamic light reflections. This automatic timepiece operates without batteries and is powered by the natural movement of the wearer's wrist through Citizen's reliable mechanical movement. The silver stainless steel bracelet complements the blue dial with its polished surface and is secured by a fold-over clasp with a push-button opening. The watch includes a date display function at the 3 o'clock position and is protected by mineral glass that resists scratches. Water-resistant up to 5 bar (50 meters), this timepiece is suitable for everyday use and can withstand splashes or brief immersion in water. The unisex design, with its balanced 40 mm case diameter, appeals to both men and women looking for a versatile automatic watch. The sunburst blue dial features silver hands and hour markers with luminous filling for enhanced visibility in low light conditions. Citizen's automatic movement offers a power reserve of approximately 40 hours when fully wound. The watch maintains an accuracy of -20 to +40 seconds per day under normal wearing conditions. The bracelet features a secure fold-over clasp and push-button opening mechanism for comfortable wear. This model represents Citizen's commitment to mechanical watchmaking with reliable automatic functionality and timeless design elements suitable for both professional and casual occasions.
