This is a diver's watch from Orient, commonly known as "Mako." The model number is AA02-C1-B. The glass surface has a thin scratch of about 7mm from 1 to 2 o'clock. There is also a scratch of about 3mm near 7 o'clock. There are no chips that are visible. The bezel has a unidirectional rotating function. The edge of the bezel is worn, and the underlying metal is visible. The luminous paint is perfect. The original strap is about 15cm long. The watch body is about 43mm, so it should fit a wrist size of about 19cm. There are no extra links. The aftermarket rubber strap has been replaced and not used much, so it is relatively clean. It is thinner compared to Seiko straps. It was purchased used around this spring, and has been lightly polished and liquid coated. There are deep scratches, but I think it's fine for use. Please note that the coating will come off if you wipe it with alcohol. It has a hacking function and a screw-down crown. The daily rate is about +20 seconds when laid flat. It has not been overhauled. It can be wound by hand and by shaking the rotor. I am selling it because I have fewer opportunities to wear it and my collection has grown. The blue dial is beautiful and easy to read, so how about adding an accent to your wrist? Please ask any questions in the comments. Please understand that this is based on my amateur assessment.
