The newly introduced Viator is the fourth model from Swiss watch maker Heritage Watch Manufactory. Established in 2010, this prestigious mechanical watch brand from Neuchâtel, after the successful launch of Tensus, Magnus and Centenus models, now introduces a new timepiece that features GMT function: a useful tool for world travelers.
Equipped with in house developed cal. 840 movement, the Viator model unites the art of traditional watch-making, unheard-of precision and extraordinary longevity with the advantages of a GMT watch.
Constructed by master watchmaker Karsten Fraessdorf, the Viator is a completely in-house developed timepiece. As a GMT watch, the Viator displays a second time zone underneath the 12 o’clock numerals. 
The immediately jumping hour allows synchronization in just a few seconds through its quick-change mechanism. Its extraordinary movement incorporates three patented mechanisms for fine regulation and hence for unheard of accuracy: Vivax precision balance, special Sectator mechanism for fine regulation of the escapement and Tenere balance cock.
The technical perfection of the movement concept of the Viator finds its counterpart in the restrained, elegant design – again penned by Eric Giroud. The dial of the Viator fascinates through its nuanced interplay of space and volume, lending the depth of its reliefs a particular character.
Inspired by the convex enamelled dials of 18th century Parisian pendulum clocks, the avant-garde dial of the Viator, with its six concentrically arranged applications, perfectly meshes with the case and the crystal and imparts an air of timeless classicism. The curved hands complement this design, following the curvature of the glass and strengthening the depth of the reliefs of the Viator. In the spirit of the housings used to protect valuable clock movements during chronometry competitions, the design of the casing visualises its origins. With its air of noble discretion and a timelessly classic appearance, the design has notably succeeded in capturing the uniqueness of the mechanism and the inner values of the Heritage Watch Manufactor timepieces in a visual sense.
With its functional and clean lines, it reflects above all the mechanical character of the chronometer. Each detail of the decoration has its origin in Switzerland.“
