Eterna may not be one of the first names that comes to mind when you mention Swiss watch brands, but it’s certainly a firm forum favourite. There are many mechanical watch lovers who are loyal fans of Eterna. One of their newest launches is the Eterna Madison Eight Days Spherodrive Watch.
Eterna established the prestigious and widely used Swiss watch movement maker ETA in 1932, now under the wing of the Swatch Group. The company have produced many innovations in their history, including the smallest production wristwatch with a Baguette movement in 1930, and an eight-day alarm watch in the 1930s with their first automatic watch being produced in 1938.
Perhaps the most famous Eterna watch was the Eterna-matic. This watch was launched in 1948. The weight ran on small ball bearings making it very efficient, hence the Eterna trademark of five ball bearings. The Eterna-matic has continued to be produced in various styles.
Getting back to the Spherodrive, there are a total of seven ball bearings in the calibre 3510 Eterna Spherodirive movement. In addition to performing for the spring barrels they can also be found in the date changing assembly and the power reserve display. The use of ball bearings eliminates the need for lubrication. The movement also follows the unspoken horological rule that the shape of it should match the case, but in truth, this has become something of a rarity for all but the most prestigious watch brands.
The Eterna Spherodrive is unmissable on the wrist, 53mm tall and 38mm wide, it’s crafted from top grade stainless steel. The case, fitted with sapphire crystal, is water resistant to 30 meters. The dial comes in three colour options including silver, grey and black, and displays the time, an oversized date and the power reserve indicator that features a red disc.
The Madison Eight-Days Spherodrive retails for around 8,530 Euros in Europe and a hefty $13,300 in the United States.
