Charles Frodsham Two-Day Marine Chronometer

• Movement - The technical name for the workings of a clock or watch, and does not include the dial or case.
• Mahogany - Mahogany is a dense, close grained red-coloured timber from the West Indies and Central America. It was first imported into Europe in the the early 18th century and its use continued through the 19th century. It was popular for furniture making because of its strength, the wide boards available, the distinctive grain on some boards, termed flame mahogany and the rich warm colour of the timber when it was polished.. The "flame" was produced where a limb grew out from the trunk of the tree, and this timber was usually sliced into veneers for feature panels on doors, backs and cornices.
  
  Some terms used to describe mahogany relate to the country from which it originally came, such as "Cuban" mahogany, "Honduras" mahogany etc. However unless the wood has been tested the names assigned are more a selling feature, rather than a true indication of the timber's origin.
• Gimbal - On a ship, a gimbal is a pivoted mounting for the compass, clock, chronometer, stoves, drink holders and other equipment which keeps the item horizontal, no matter which way the vessel is leaning.
