The Citizen Eco-Drive AT2396-86E is a sophisticated men's wristwatch featuring Citizen's proprietary Eco-Drive technology, which converts any light source into energy, eliminating the need for battery replacements. This watch combines Japanese precision engineering with elegant design elements suitable for professional and formal occasions. The stainless steel case measures 41 mm in diameter and approximately 10 mm in thickness, providing a substantial yet comfortable presence on the wrist. A sapphire crystal ensures exceptional scratch resistance and clarity. The dial showcases a clean, minimalist design with silver-colored hands and hour markers against a deep black background, complemented by a date window at the 3 o'clock position. It is water-resistant up to 10 bar (100 meters), making it suitable for swimming and snorkeling. The bracelet is made of solid stainless steel with a fold-over clasp for secure closure and comfortable wear. The movement features an eternal calendar function that automatically accounts for varying month lengths and leap years until 2100. The accuracy is within ±15 seconds per month under normal temperature conditions. Luminous hands and indices ensure good readability in low light. The watch has a power reserve of approximately 180 days when fully charged, with an energy-saving feature that stops the second hand in darkness. The total weight is around 150 grams for a balanced feel on the wrist. This timepiece represents Citizen's commitment to sustainable watch technology combined with traditional watchmaking craftsmanship.
