This is a CITIZEN NY0120-01E! I haven't worn it much, and I've had a protective sticker on the glass since I bought it. I used a NATO strap instead of the original strap. *I've lost the original strap.* I'll also include a non-original strap. I'm also including a watch winder, so I think it's a great deal. *I lost the power cord, but it works fine with AA batteries.* It's 200m water-resistant, so you can use it without worry even when working with water! Also, the size is not too big or too small, so it can be matched with various outfits. It's in good condition, but please understand that it's used. ◆ Mechanical automatic movement ◆ Stainless steel case ◆ Rubber strap ◆ Size: Diameter approx. 41mm, Thickness approx. 12mm ◆ Day-date calendar ◆ Anti-reverse bezel ◆ Screw-down crown ◆ Screw back ◆ 20 ATM water resistance (200m water resistance) ◆ Warranty, instruction manual, and box included CITIZEN, a Japanese brand known worldwide. It's a watch brand that Japan is proud of, highly regarded overseas for its excellent performance. This product is an automatic 200m diver's watch released for overseas markets. It seems like it will be an essential piece for the sea season. *Please understand that I may cancel the listing suddenly.* *Diver watch, Promaster, diver's watch*
