Ship clocks

Ship's clocks for maritime flair

The Hermle brand is a special pioneer in the field of ship's clocks. For eample, most ship's watches nowadays are directly linked to an international search query for Hermle ship's watches, as the high-quality workmanship precedes the brand's reputation far beyond the country's borders.

The special position of the ship's clocks derives from the possibilities that these timepieces offered to shippers. Ship's clocks not only reliably measure the time, but also display important data for seafaring via such indispensable measuring devices as the barometer (measurement of air pressure) and the thermometer.

Even the first models of this category had an important function, the determination of geometric length. This made it possible for the first time to determine the longitude very precisely and thus to determine the position on the high seas very precisely. The longitude was determined by the eact measurement of the current time at a certain point (whose longitude is known), this value was compared at a second point (whose longitude had to be found out) by reading the current time of day via the chronometer and calculating the longitude of the second point of view. If there is a time difference of four minutes, the longitude is changed by eactly one degree.

In order to meet the demands of a watch suitable for ships, Hermle ship's watches have been made of particularly high-quality materials. Many are made of brass or partly of fine woods.
