Tide machine clock core can be said to be the only heng rong horological manufacturer produces only one movement, heng rong clock 22 years to watch machine core research and development have many suantiankula, including tidal clock movement development cost a lot of kung fu.Tidal clock movement in today's achievements have been a lot of watches and clocks industry enterprises recognized and widely used, tidal movement is mainly the needle Marine fisheries, Marine aquaculture, tourism, fishing, etc.

Ocean tides is the natural phenomenon of the sea, is caused by the factors such as the relative motion of the earth and the moon, and has its inherent law.Along with the social development and changes, especially towards Marine economic development today, grasp the accurate tidal law is necessary.Tidal clock movement principle and quartz clock movement is a bit different, as tidal movement in the walk is 12 hours and 25 minutes 15 seconds, also said each walk slower than quartz clock time 25 minutes and 15 seconds, but for the time can accurately show the ocean tides of climax, time, and identifies the distance is high, the low time.
