SA Manufacture Horlogère Suisse
Born to be great
We are undoubtedly
witnessing the beginning of a major trend for the coming years – the demand
for large, even very large watches. These watches are not only designed
to display the time, but also to express the personality of the wearer.
Today’s women often like to use large watches, while men turn to even
A 16 1/2 line
movement on one’s wrist
To embrace this trend, a new calibre has emerged: the Valgranges, an impressive
16 1/2 line movement.
From Valjoux to
A select origin entails a special obligation for excellence. The Valgranges
calibre is indeed of high-ranking birth. Its name shows at a glance that
it was conceived along the lines of the famous Valjoux calibre. Designed
in 1973 in the Vallée du Joux, this standard diameter (13 1/4 lines) automatic
mechanical movement has become a reference movement in Swiss mechanical
watchmaking. It is the timekeeper chosen by an extensive number of brands
and its name is recognised as a pledge of quality by both professionals
and connoisseurs. Developed in Granges (Grenchen in German), where the
manufacture ETA was founded nearly a century and a half ago, the Valgranges
has all the qualities of the 7750 movement. And maybe even something more…
A calibre that
embodies the ETA values
Watchmakers are familiar with the exceptional quality of ETA movements.
Moreover, the company has the exceptional power to manufacture quality
precision products. The Valjoux is prized for its reliability, its robustness,
its high precision and also for its power: The mainspring rewinds with
extraordinary speed – it just takes a few movements of the wrist to furnish
the watch with energy. For the spring to reach its full 46 hours’ power
reserve, a few hours of wrist movement will suffice. Of course, all the
other advantages of the Valjoux are also included in the Valgranges calibre.
Like the Valjoux,
the Valgranges calibre is available in a series of movements equipped
with different features but all of identical dimensions (same diameter,
same height), an uncommon advantage for clients.

Following a centuries-old tradition, watchmakers use lines rather than
millimetres to describe the size of the movement’s diameter. This measurement
is generally indicated as a triple apostrophe, so 16 1/2 lines is written
as 16 1/2 ´´´, or 37.22 mm diameter.
The line, or Parisian line, is an ancient watchmaking measurement that
predates metrification and is a direct descendant of the French pied (
foot ) measurement used under the Ancien Régime. Each line is equivalent
to 2.2558 mm, which is rounded up to 2.26 mm for ease of calculation.
In the past the French foot used to correspond to 12 inches measuring
12 lines each.
