Product Description

US Navy Chronometer From the Civil War

A field tested piece of Civil War history, this Eggert & Sons Marine Chronometer was on the USS Powhatan during the Federal forces blockade of the Confederate states during the Civil War. Used to determine the ships longitude, this chronometer helped ensure the ship was on the correct course and was surely put to the test chasing down blockade runners and the C.S.S. Sumter in the West Indies. A unique, and beautifully maintained piece of nautical history, this particular chronometer has service records dating from 1856-1880.

The chronometer is in excellent condition and still runs, it is missing the clock lid as it was a common practice for the ship’s captain to remove the lid for better viewing. A full​ ​brass​ ​gimbal​ ​interior​ ​holds​ ​this​ ​chronometer, and it is housed​ ​in​ ​a beautiful​ ​mahogany​ ​brass​ ​bound​ ​case with glass top, bearing the name of the manufacturer. This sits in the outer box (non-original) which has a leather strap for carrying. After serving aboard the U.S.S. Powhatan, it was transferred to the U.S.S. Gettysburg (June 1865), and later the U.S.S. Lackawanna (April 1880).

A chronometer is a portable timekeeping device of great accuracy, particularly used for determining longitude at sea. Ordinary clocks proved to be of no use at sea because of temperature changes and the ship’s motion. Several​ ​unfortunate​ ​disasters​ ​at​ ​sea ​prompted​ ​the​ ​British government​ ​to​ ​create​ ​a​ ​Board​ ​of​ ​Longitude​ ​to​ ​award​ ​£20,000​ ​to​ ​the​ ​first​ ​man​ ​who​ ​developed​ ​a chronometer​ ​with​ ​which​ ​longitude​ ​could​ ​be​ ​calculated​ ​within​ ​half​ ​a​ ​degree​ ​at​ ​the​ ​end​ ​of​ ​a voyage​ ​to​ ​the​ ​West​ ​Indies.

John Harrison had become interested in making chronometers in 1728, and by 1735 he completed his first clock and submitted it for the British prize. ​In 1762​ ​Harrison’s​ ​famous​ ​No.​ ​4​ ​marine​ ​chronometer​ ​was​ ​found​ ​to​ ​be​ ​in​ ​error​ ​by​ ​only​ ​five seconds​ ​(1​ ​1/4′​ ​longitude)​ ​after​ ​a​ ​voyage​ ​to​ ​Jamaica.​ Harrison’s​ ​successful​ ​design led​ ​to​ ​further​ ​investigations​ ​by​ ​others​ ​and​ ​eventually​ ​to​ ​the​ ​modern​ ​marine​ ​chronometer.​ A​ similar ​chronometer​ ​by​ ​Eggert​ ​&​ ​Son​ ​circa​ ​1850​ ​is​ ​in​ ​the​ ​collection​ ​of​ ​the​ ​National​ ​Maritime Museum,​ ​Greenwich,​ ​London.

This includes copy of the original paperwork which is on file at the US Naval Observatory which is in Washington, D.C.
