Mastering Time: The Intricate Craftsmanship Behind Chelsea Clock Company's Marine Chronometers

Chelsea Clock is one of the oldest and largest clock manufacturers in the United States well regarded for our handcrafted timepieces. These timepieces include traditional and modern clocks, barometers, tide instruments and even chronometers. In fact, our precision chronometers are so reliable, that they were incorporated into US Navy ships during WWII and helped other ships navigate the Arctic.

While our master clockmakers have made chronometers for many years, not many people know about them. Even dedicated clock enthusiasts might not know what chronometers are! Learn about the intricate craftsmanship and other important qualities that make our marine chronometer special from our team here at Chelsea Clock:

What is a Chronometer? Why are Chronometers Important?

A chronometer is an extremely accurate mechanical timepiece primarily used in sea navigation, though there are home chronometers and even modern chronometer watches. However, sea chronometers are special in that they help keep track of time and help determine a ship’s position at sea.

While humans have been sailing the seas for hundreds of years, accurate navigation at sea when land was out of sight was difficult. By using the stars at night, sailors could come up with a prediction of where they were, but for many years there wasn’t a common way for sailors at sea to determine one’s precise location when in the middle of the ocean.

A solution came from the marine chronometer in the early 17th century. English clockmaker John Harrison developed a series of marine clocks that would serve as the foundation of the modern chronometer. By comparing the local time through standard watches, the time on the chronometer and the angle of the sun through a tool known as a sextant, marine navigators could determine their location more precisely than ever before.

How Long Has Chelsea Clock Made Chronometers?

Founded in 1897, Chelsea Clock has been making marine chronometers and other navel timepieces for over a hundred years. We patented our first true navel clock, the Ship’s Bell timepiece, in 1900. Just a couple of years later, our prestigious clocks were known to be so reliable, that the United States government began to order our marine clocks for official use.

Over the coming decades, more and more naval vessels relied on Chelsea Clock craftsmanship to navigate the seas. Admiral Richard Byrd was able to complete an expedition across the Atlantic Ocean and to the Antarctic Plateau with the aid of Chelsea Clock naval timepieces. Admiral Byrd even wrote a personal letter of gratitude to Chelsea Clock, thanking our company for the assistance in 1936.

WWII followed a few years later, and Chelsea Clock was ready to contribute to the cause with our latest timepieces. This includes timepieces with upgrades such as automatic bell chimes at key times during the day and radio room clocks helping sailors keep track of transmission and silence periods.
