Eterna Matic
The Eterna-Matic (Ref 633.2021.41) is an underrated watch as a prime example of the 1970's transition to ball bearing rotor technology. Sold on Chrono24
The Eterna Matic line is revered in horological history for the use of the five ball bearings in the rotor - a groundbreaking design that drastically reduced friction and wear. This technology is represented by the iconic five-dot logo visible on Eterna watches. The heart of the watch is the Calibre 2824, a highly durable and accurate movement with a fast beat rate (28,000 VPH) that provides smooth, sweeping seconds.
The 36mm stainless steel case wears beautifully on the wrist, reflecting a timeless mid century elegance that has returned to popularity. It's a very practical and stylish daily wear that won't break the bank fitting well in any collection
