The Eterna Calibre 1463 is a compact, high‑frequency automatic movement from the late 1960s, designed mainly for elegant smaller watches and notably fitted in Eterna’s Golden Heart Lady models. It’s a refined, jewel‑like movement that appeals to collectors who appreciate late‑1960s Swiss engineering in a petite case.
Why Collectors Like It
It’s a signature movement for Eterna’s Golden Heart line, giving the watch a distinctive “eternal” heart-shaped rotor and a strong brand identity of the 1960s.
The movement is fully signed on the bridge and rotor, which adds authenticity and charm for vintage enthusiasts.
As a compact calibre, it’s ideal for smaller dress and ladies’ watches, making it a good choice for collectors of vintage petite timepieces.
It’s robust for its era, with Eterna’s proprietary shock protection and typical finishing of a quality Swiss house of the 1960s.
