[Citizen] Watch Citizen Collection Mechanical NH9110-90E Men's Black

・【[Citizen] COLLECTION: Pursuing the fundamental performance and design of watches】 An open-heart mechanical (automatic + manual winding) wristwatch. It features a caliber equipped with a “second hand stop function” that stops the second hand when the crown is pulled out for time setting. This model is packed with the allure of mechanical watches, including a see-through back that allows you to enjoy the rotating weight and the movement of the mechanism. ・【The allure of a mechanical watch with an open heart】 The open-heart design allows you to enjoy the delicate movement of the escapement, the heart of a mechanical watch, from the 7 o’clock position on the dial. A pattern drawn vertically from the 12 o’clock position to the 6 o’clock direction creates a classic impression. A basic design combining a practical metal band with black and blue dials. The back case is a see-through back that allows you to enjoy the rotating weight and the movement of the mechanism. ・【Considerations for long-term use】 We have pursued improved durability with the desire for you to use it for a long time. It protects your valuable watch from all kinds of scenes with 10 ATM water resistance performance and highly durable sapphire glass. ・【Mechanical self-winding watch】 This is a mechanical self-winding watch that uses a mainspring as its power source. When you wear the watch, the rotating weight inside the watch moves with the movement of your arm, automatically winding the mainspring. You can also wind the mainspring by hand. The see-through back allows you to view the movement of the rotor and escapement. (You can also check the operating instructions on the manufacturer’s website.) ・【Product Details】 Mechanical wristwatch, automatic + manual winding, -20 to +40 seconds/day, approximately 42 hours (at maximum winding), sapphire glass, case & band: stainless steel, 10 ATM water resistance.
