CITIZEN Collection NH9131-73L Automatic Open Heart Watch Blue Dial Stainless Steel Men's

The CITIZEN Collection NH9131-73L is a classically modern mechanical watch that highlights the beauty of traditional watchmaking. Designed with a refined yet contemporary aesthetic, this model features an open-heart display at the 6 o’clock position, allowing you to admire the delicate movement of the balance wheel—the heart of the mechanical watch.

The deep blue dial is accented with silver-tone indexes that stand out with crisp clarity. A distinctive radial pattern spreads outward from the circular open-heart window, adding depth and elegance to the design. The case back is finished with a see-through construction, offering a view of the rotating rotor and the intricate mechanical movement inside.

This timepiece is powered by a Japanese automatic movement (Caliber 8229) with both automatic and manual winding capabilities. It operates with an accuracy of -20 to +40 seconds per day and provides approximately 42 hours of power reserve when fully wound. The movement is driven by a mainspring, which is wound automatically by the motion of the wrist while worn.

Crafted with a stainless steel case and bracelet, the watch delivers durability and a polished presence suitable for business or formal occasions. The bracelet features a triple-fold push-button clasp for secure and comfortable wear. The dial is protected by crystal glass, and 5 bar water resistance makes it suitable for everyday activities such as hand washing and light water exposure.
