Citizen COLLECTION Mechanical Watch [CITIZEN] NP1010-78E Men's

[CITIZEN COLLECTION: Pursuing the fundamental performance and design of a watch] An open-heart mechanical (automatic + manual winding) wristwatch. Equipped with a caliber that features a "second hand stop function" that stops the second hand when the crown is pulled out to set the time. This model is full of the charm of mechanical watches, such as a see-through back that allows you to enjoy the rotating weight and the movement of the mechanism. [The allure of a mechanical watch: Open Heart design] This watch features a three-dimensional, substantial design combining two separate rings. It is equipped with carefully selected functions, such as a sub-dial with a 60-second hand. The open-heart design allows you to enjoy the delicate movement of the balance wheel, the heart of the mechanical watch, from the 7 o'clock position on the dial. The case back is see-through, allowing you to enjoy the rotating weight and the movement of the mechanism. The band size can be easily adjusted by yourself with a simple adjustment mechanism. [Features for Long-Term Use] With the desire for you to use this watch for a long time, we have pursued improved durability. 10 ATM water resistance and highly durable sapphire glass protect your precious watch from all kinds of situations. [Mechanical Automatic Watch] This is a mechanical automatic watch powered by a mainspring. When worn on the wrist, the movement of the arm causes the internal rotating weight to move, automatically winding the mainspring. It can also be wound manually. The watch features a see-through case back, allowing you to see the rotor and balance wheel in action. (Operating instructions can also be found in the manufacturer's website.) 【Product Details】Mechanical wristwatch, automatic and manual winding, -20 to +40 seconds/day, approximately 42 hours (when fully wound), sapphire crystal, case and band: stainless steel, 10 ATM water resistance
