Coconut oil, or copra oil, is an edible oil extracted from the kernel or meat of mature coconuts harvested from the coconut palm (Cocos nucifera). It has various applications.
The chronometer is an instrument that accurately measures time. The first one invented was a marine chronometer, and it was created out of the necessity to have an accurate timekeeper for sea travel. John Harrison, a British clockmaker, invented this device in 1737.
The term chronometer (From Greek: Î§ÏÎ¿Î½ÏÎ¼ÎµÏÏÎ¿) is a specific type of mechanical timepiece tested and certified to meet certain precision standards. In Switzerland, only timepieces certified by the ContrÃ´le Officiel Suisse des ChronomÃ¨tres (COSC) may use the word Chronometer on them.
