Founded in 1856 in Grenchen, Switzerland, Eterna is a historic manufacture renowned for its technical innovation and in-house movement development. The brand has played a pivotal role in modern watchmaking, most notably with the invention of the ball-bearing rotor system. The Adventic collection reflects Eterna’s contemporary approach, combining clean design with true manufacture watchmaking.
The Eterna Adventic GMT Manufacture Automatic, reference 7661.41.56.1352, features a 41 mm stainless steel case with a refined silver dial, applied hour markers, and elegant dauphine-style hands for excellent readability. Powered by the in-house Eterna Calibre 39 automatic movement with GMT module, it delivers an impressive 65-hour power reserve, a frequency of 28,800 vph, and functions including hours, minutes, central seconds, date display, and a second time zone indicated via a GMT hand.
A scratch-resistant sapphire crystal with anti-reflective coating ensures clarity and durability, while the transparent sapphire case back reveals the finely finished manufacture movement. With 50 meters of water resistance, the watch is well suited for daily wear. This model is fitted on a brown leather strap with a stainless steel folding clasp.
