This is a Hamilton Jazzmaster Seaview Chronograph, a popular model purchased in 2023. The model number is H375120. It features sapphire crystal and is water-resistant to 10 bar (100 meters). The black dial gives it a sharp impression. Equipped with a chronograph function, it's a practical watch. I've taken good care of it, so it's clean for its age, but there are many small scratches from use, so please check the photos. I haven't replaced the battery since purchase. It's still running without any problems. Accessories: Original case, instruction manual, spare links Bonus: Two leather straps from a different brand, a genuine Hamilton buckle, and a D-buckle for leather straps.
