Living in a peaceful and affluent part of the world, we enjoy the best of modern life. Let us never forget, though, what creative and adventurous people have done in the past. 240 years ago, Captain James Cook was sailing around the world discovering far-flung places and claiming them for the British Empire. He was only able to do so thanks to the “H4″ Marine Chronometer of John Harrison, which showed him exactly the right time (with a difference of only a few seconds over the whole trip).

Rolf Lang Dresden GmbH, a German manufacturer of exclusive watches, is glad to present today the most exclusive marine chronometer in the world – «GOLDEN H» in memory of John Harrison’s «H4».

The limited edition consists of only 6 pieces worldwide, one unique piece for each time zone, and is made of solid 18 carat gold with exclusive rare Venetian Murano glass in the globe shell and suspended in a massive gold gimbal to compensate for the movement of the ocean wave.

Exclusiveness. The first (!) marine chronometer in the world with the Murano Glass unfolding housing and disseminated values. Such products are presented in the world market no more than once in 100 years!

Goodwill. Custom selection: production output of GOLDEN H chronometers is limited. All in all, there are 6 products in the whole world.

German Quality. All 387 parts of GOLDEN H chronometer are made, polished and assembled manually. No industrial assembly! Made in Germany for sure.

Greatness. It takes 6 kg of pure gold to produce one chronometer… But you can order it in silver or platinum.

Accuracy. The production accuracy of the parts is 2…3 µm, it is almost 100 times thinner than a human hair! Assembling such parts by the fourth-generation watchmaker, who is invited by the best museums in the world for restoration of rarities, results in the chronometer with ideal accuracy movement: at least 1 sec/week. The watch-work is completely self-designed.

Warranties. All Rolf Lang chronometers are covered by a lifetime warranty. It means that you can effectively use them your whole life, your children and grandchildren will inherit them as a very expensive rarity.
