Deck Watch.
Originally, Marine chronometer, and deck watches were intended to be used on ships to determine longitude according to the principles of celestial navigation. Until 1754, the position of an ocean-going vessel could not be known with the latter being estimated from the last known position, that is to say from the last known earth. Mariners could determine their latitude accurately. In order to be able to determine the longitude, it is necessary to have a reliable, stable and precise time measuring device.
The ship's clock, is located in the ship's major stations, such as the gateway, radio pc or engine room.

Originally, Marine chronometer, and deck watches were intended to be used on ships to determine longitude according to the principles of celestial navigation. Until 1754, the position of an ocean-going vessel could not be known with the latter being estimated from the last known position, that is to say from the last known land. Mariners could determine their latitude accurately. In order to be able to determine the longitude, it is necessary to have a reliable, stable and precise time measuring device.
Originally, deck watch were meant for navigation to measure the exact time during sextant use, it is necessary to have a reliable, stable and precise time measuring device.
