Product Description

The ZENITH Chronomaster El Primero Open 03.3300.3604/21.M3300 is a refined and high-performance men’s chronograph, showcasing the brand’s legendary watchmaking expertise. It features a 40mm stainless steel case with a matte black open-worked dial that reveals part of the El Primero 3604 automatic movement—a nod to ZENITH’s heritage of precision and innovation. The chronograph is equipped with Luminova-coated hands, small seconds, and a see-through case back, all protected by a scratch-resistant sapphire crystal. With 100m water resistance, it combines durability with elegance for everyday wear. This pre-owned watch is rated Rank A and shows only slight scratches on the case, bezel, bracelet, and buckle, while the sapphire crystal remains flawless. It fits wrists up to approximately 21cm and has a case thickness of 14mm, offering a balanced presence on the wrist. Included with the watch are the original manufacturer’s warranty (purchased in Japan in July 2022), the branded box, and booklet—making it a well-documented, stylish choice for enthusiasts of Swiss horology.
