Eterna timepieces have been highly regarded and celebrated over decades for their precision automatic movements. Founded in 1856, this prominent Swiss watchmaker is noted for introducing a ball-bearing mounted rotor system on its automatic timepieces in 1948, which reduced friction and resistance in the weight that wound the mainspring of the watch.

The ball bearing system not only reduced the wear and tear on the internal parts of the automatic timepiece, it also increased the accuracy as well. The  design instantly catapulted the Eterna’s presence in the horological industry as many other watch brands sought to use Eterna to produce the inner mechanisms of their timepieces.

The five ball bearing design was also adopted by Eterna as its corporate logo and it soon appeared on the dials of the brand’s timepieces.  Prior to the ball bearing design, Eterna was heralded for its introduction of its women’s wristwatches in the early 1900’s and its patented alarm wristwatch in 1908.ETERNA-7720-41-43-1228

In the 1960’s, Eterna introduced the Eterna Matic 3000 Dato automatic men’s watch and the women’s Sahida automatic watch. Both timepieces were 4mm thick or less and the thinnest watches featuring automatic movement inside.

In the late 1990’s Eterna was sold to Porsche and soon marketed watches under the Porsche Design label. In 2007, Eterna introduced the Spherodrive Eterna Matic, featuring a new and updated ball bearing mechanism. Three years later the brand introduced the Madison Eight Days men’s watch, which featured the Spherodrive mechanism along with an eight day power reserve.

You’ll find the Madison Eight Days timepiece along with other new collections for men and women from the Eterna Tangaroa, Artena and 1948 collections at popular online retailer during the site’s week-long Eterna watch event.

The Madison Eight Days men’s timepiece offers a highly distinguished profile with its polished Tonneau shaped case and genuine black alligator strap. The stationary raised bezel frames the textured tone-on-tone black dial with luminous hands and hour markers. A window at the 2 o’clock hour reveals the automatic date calendar. The 8-day power reserve indictor above the 7 and 8 o’clock hours adds to the stylish design.

The exhibition skeleton caseback lets you see the intricate automatic Swiss movement inside.  The Madison watch is 38mm wide, 13mm thick and is water-resistant to 30 meters.
