From Chinese Watch Wiki

Jinmao (金锚) is a watch brand produced by Qingdao Watch Factory , launched in 1975 and still in use today. The first Jinmao watches used the hand-winding mechanical Chinese Standard Movement , and were a grade 2 brand in the grading system in use at the time. The name means "Golden Anchor", and the brand's logo is a stylised ship anchor. The anchor logo and other nautical imagery often appear on the dial, crown and caseback of Jinmao watches. This reflects the fact that the city of Qingdao where the watches are made is a coastal city containing a major seaport and a naval base.
