Size: No. 8 (Adjustable) Colors: Wine Red, Silver Specifications: Hand-wound This is a SEIKO ring watch. It's beautiful, sparkling with cut glass♪ I've had this for about 5 years, and it's been working without any major issues. I haven't had it overhauled or maintained, so I'm not sure what will happen in the future... It looks beautiful to the naked eye. There are small scratches and dirt as shown in the images when magnified. It's an old item, so I appreciate your understanding before purchasing. □■□■ SEIKO ring watches were mainly manufactured and sold from the late 1960s to the 1970s (around 1967-1979). They are rare mechanical (hand-wound) accessory watches. Due to the rise of quartz watches in the early 1970s, the production of mechanical ladies' movements ended, so the manufacturing period was short, and existing ones are considered valuable. The manufacturing year (the last digit of the Western calendar year) and month can sometimes be identified from the serial number on the back of the watch. It seems there was a movement change in 1970. ■□■□
