The new Prima by Niton (incl. a Geneva Seal movement) & its background
Niton was founded in 1919 by three watchmakers, Jeannet, Morel and Bourquin, the latter two of whom were former employees of Vacheron Constantin.
In
1922, it became the "
Manufacture des montres Niton S.A."
The brand begins a second life today thanks to Yvan Ketterer (right) and Leopoldo Celi (left).

Their introductory model, called the Prima, is a “striking” jumping hour watch, meaning that every time the hour jumps, the mechanism also strikes a copper gong embedded in the case itself, thus creating a quiet, soft chime.

The
source of
inspiration of this design comes from the
past of the brand.

Astonishingly, the
Prima is powered by a
shaped manual winding movement bearing the
Geneva Seal.

The case measures 27 x 42 x 7.9 mm and seems to sit perfectly on the wrist.

The Prima is a limited edition of 19 pieces in pink gold and 19 in platinum (a nod to the date of birth of the brand, 1919).

During the 1920s and 1930s, the brand has made several jump hour watches with various designs. Oftentimes, these watches were made for other brands, like Cartier or Gübelin.
All of them were already powered by exquisite shaped manual-winding calibers bearing the Geneva Seal.
Here's an overview of these models from the past: I have focused only on the models with the same three-part dial layout (hours, minutes and small seconds).

TWO EXAMPLES FOR CARTIER WITHOUT NUMBER
ONE LAST EXAMPLE FOR GÜBELIN WITHOUT NUMBER

By the way, the
name Niton comes from
two glacial erratics originating from the
Alps which formed and later found their way to the
Geneva Lake harbor.
These
enigmatic stones were named "
Pierres du Niton" (Niton stones) and soon became the national
landmark for the Swiss topographic height measuring system.
Thanks for reading.
