0 comment

Edouard Koehn, a brand that has been based in La Chaux-de-Fonds, Switzerland, for several years now has four different collections. Of particular interest is the model he introduced in 2021 as part of the World Heritage line, which combines two practical complications. world time and alarm function. Some mechanical watches offer the following combinations: Alarm with GMT or dual time display, the fusion of alarm and world time is rare in the world of watches. In 2023, Edouard Kehn presents the limited edition World Heritage II series. This series maintains the same concept and basic movements while offering a fresh presentation for enthusiasts to explore. I have actually experienced it, so I would like to share with you my impressions.

First, a word about the name. Edouard Kehn (1839-1908) was a watchmaker and former co-owner of Patek Philippe & Cie (world time watch specialist…) The roots of this name date back to his 19th century. It has re-emerged in the field of modern watchmaking. Bernard F. Fleury is an industry veteran known for his role as CEO of Vulcan (alarm clock expert…) in the early 2000s. He played a key role in restoring the brand’s reputation within the company. industry. Bernard Fleury discovers a watch inscribed with Edouard Kane’s name at an auction. Further research led to interesting discoveries, exciting enough to convince Fleury of the possibility of the name and the rights he purchased in 2015. Edouard Kane created two collections: a modern chronograph called the Tempus, and a World Heritage watch with universal time and alarm functions.

Edouard Kane’s World Heritage II series is comprised of five references, distinguished primarily by the color of the dial. This model is housed in a 42 mm diameter case with a classic and elegant design, but is made of grade 5 titanium and has a height of 14.5 mm. It features double-sided sapphire crystal and guarantees water resistance up to 50 meters.

The bezel is thick and has a polished finish that shines and blends in with the other surfaces. The curved lugs are seamlessly integrated into the middle case, and the case back is securely secured with six screws. The crown at 2 o’clock features the brand’s wind rose symbol and is used for winding, setting the time, and adjusting the world disc. The crown at 4 o’clock is marked with a bell and is used for setting and winding the alarm. Both crowns are grooved for easy handling. Despite its large size, this watch is made from durable yet lightweight titanium, ensuring no weight and comfortable wearing. This can be a little confusing at first, as the watch is significantly lighter than you would expect given its size. The use of titanium provides optimal acoustics for the alarm function and emphasizes consideration to both form and function.

While the case design exudes simplicity, the dials of the World Heritage II series reveal fascinating complexity. Offered in a palette of icy blue, silver, green, blue, and anthracite, each dial is built around a central disc that features a raised image of the world’s northern hemisphere. This central disk is surrounded by rings that display locations representing different time zones. Notably, London is highlighted with a red triangle denoting an important GMT zone, while Paris giving way to Geneva represents the city’s growing importance to watchmakers. Maybe.

Next to the central disc with the map and time zone location rings is a 24-hour fixed ring that rotates once every 24 hours. The light gray area represents daytime (7:00 to 17:00), and the black area represents nighttime (18:00 to 6:00). In particular, at the 12 o’clock position there is an image of the sun representing noon, and at the 24 o’clock position there is a crescent moon representing midnight. Another key element is the colored guilloche ring that houses the outer minute track and applied hour index. The faceted and polished hour markers are coated with Super-LumiNova for improved legibility in low light. The index at 12 o’clock is replaced by a proud display of the brand’s metallic wind rose logo. This is also applied, but it does not glow in the dark.

The central alpha-type hour and minute hands, coated with Super-LumiNova, are adjusted by a dedicated crown in position 3. The stop seconds function allows precise time setting. In position 2, this crown quickly adjusts the world time disc. Naturally, the time zone must match the current time on the 24-hour ring. That way you can read the time accurately in other places around the world.

Finally, the outermost ring of World Heritage Site II is graduated at 15 minute intervals per hour and serves the purpose of setting an alarm. To activate the alarm function, the crown at 4 o’clock must be pulled to position 2. You can set the desired alarm time by rotating the central hand with the red arrow counterclockwise. Additionally, winding the designated alarm barrel is accomplished by placing the crown in position 1. To activate the alarm, the crown must be pulled to position 2. This is a solution that is effective enough to use your watch as an alarm clock, even if it is not the most practical one. If you accidentally push the crown back while wearing your watch, you’ll be in trouble.

The automatic caliber EK-MVTWTA01 is visible through the transparent sapphire crystal case back, with details such as the circular pattern, the Geneva stripes adorning the central oscillating mass mounted on ball bearings, and the sunburst finish on the wheels and blued screws. Reveal the finished product.

Developed in collaboration with Concepto, an independent manufacturer famous for producing luxury mechanical movements from La Chaux-de-Fonds, this caliber is derived from the A. Schild AS5008 base and offers a wide range of interesting solutions. . This is a typical configuration, with a double barrel that simultaneously winds the watch and functions as an alarm. But what sets it apart is the central automatic rotor’s ability to wind both barrels in their respective directions. The EK-MVTWTA01 caliber boasts a 48-hour power reserve and operates at 28,800 vibrations per hour.

To complete the ensemble, Edouard Kane pairs his World Heritage II watch with an alligator leather strap (22mm). This strap is available in a variety of color options to complement each dial variation and is secured to your wrist with a deployment buckle featuring a security push button. Limited to 88 pieces in each color variant, Edouard Kane’s World Heritage II is available at an affordable price. Swiss franc 8,500 – This seems very reasonable for such a complicated watch with an intricate dial and titanium case.
