World Heritage: 
First variations of dials and leather straps.

Following the success of its World Heritage model presented in 2021 with an anthracite dial, the independent Swiss watch brand Edouard Koehn is continuing the development of this collection with two new dials, one silvered and one black, associated with beautiful coloured leather straps that enhance the richness of this very watchmaking piece. As for the rest, the technical characteristics that made the first model a success have been retained: the association of two functions, on the one hand a "world time" and on the other hand an alarm. All this in a 42mm titanium case housing an exclusive automatic calibre.

This World Heritage Edouard Koehn thus offers a rare duo on the market. Indeed, this timepiece combines the world time function with the alarm function. Two complications that are very useful for travelers, since one allows one to see at a glance the world time in one of the 24 time zones, while the other allows one to wake up in time to catch a plane!

To give a contemporary touch to this otherwise very classic timepiece, very sixties in its design, this Edouard Koehn is proposed in a 42 mm case, waterproof to 50 meters, made of grade 5 titanium which, in addition to being extremely light and hypoallergenic, allows for an optimal alarm acoustics! This metal transmits sounds particularly well.

The first version had a beautiful anthracite dial. Today, the brand is enriching this collection with the arrival of two new dials: one silver and one black. Two great classics that have kept the specificities of the first anthracite version. Indeed, despite the numerous information offered on the dial, it remains perfectly legible in any occasion!

The main cities in each time zone appear in the center, associated with a 24-hour ring with day ⦁ in the light grey part - and night - in the black part. Two large Alpha hands with luminescent material mark the passing of time associated with Arabic numerals (3,6 and 9) and applied indexes on a silvered or black sunray ring depending on the version. The perimeter is reserved for the alarm function, each hour being subdivided into 15-minute portions. The alarm time can be set by means of the crown located at 4 o'clock; it is indicated by the thin hand with a red arrowhead.

As for the engine, this worldtimer-alarm features a latest-generation mechanical automatic movement, the EK-MVTWTA01, reworked in collaboration with Concepto, an independent manufacturer of high-end mechanical movements based in La Chaux-de-Fonds, Switzerland. With a double barrel, it beats at a frequency of 4Hz and offers a beautiful 48-hour autonomy.

Another new feature in 2022 is the arrival of brand-new calf leather straps that perfectly highlight the dials. A navy blue that evokes the blued steel hands and two more summery versions, a white and a sky blue leather that offer to these timepieces a summer outfit that suits them perfectly.

The Edouard Koehn brand was relaunched in spring 2020. As a reminder, Edouard Koehn began his career as a watchmaker at the court of the Grand Duchy of Saxony-Weimar-Eisenach and created his own eponymous brand in 1891.

This watchmaker, who headed Patek Philippe, was always a fan of the unique object and the very small series. This spirit is perfectly preserved today with these watches marketed in limited series produced in Switzerland at La Chaux-de-Fonds, in small quantities.
