Del Boy's pounds 6m watch does exist.

Few watches have made as big an impact on the world as John Harrison's H4 "sea watch".Harrison is largely a forgotten hero.The next generation of Harrison's timepiece, the Longitude H6, will be launched on March 4th.

The greatest challenge of the time was the discovery of a method to determine Longitude at sea.The British parliament created the Longitude Act in 1714 to reward the discovery of a reliable method after many famous ships were lost to wrecks.The testing conditions at sea made it impossible to establish a reference point and time at the ship's location.

The first timepiece so accurate it could be used to measure Longitude was created by John Harrison, a self-educated clockmaker who dedicated his life to advancement of precision timekeeping.Ed Harrison, a relative of John Harisson, co-founded The Longitude Company with the goal of bringing new generation of famous Longitude watches.

The H6 has a vintage look and an inspiring story to tell, while still feeling modern and contemporary.The domed glass and face of the watch is reminiscent of Harrison's last timepiece, and is coupled with a steel case and contemporary color combinations.

The H6 has a mechanical movement.A long term vision for the Company is to develop a movement that integrates some of the technical features of Harrison's timepiece into their movements.

The first in a new line of watches, the Longitude H6 is the latest timepiece that changed the world.You can support the campaign and get a beautiful piece of history.The early bird price for the Longitude H6 is $325USD which is 40% off the retail price.
