This may be a unique timepiece up for sale, at least I have not seen anything else like it. This Eterna-Matic Chronometer appears to date to 1992, possibly celebrating 60 years of independence of Eterna from ETA (now under the Swatch banner). One doesn’t see many of these pieces here in Canada as Eterna focused their marketing on Europe and Asia. The higher end jeweler Birks used to be their main Canadian seller, but no longer. This one could be unisex, worn by either a man or a woman. With the gold bezel, it has a bit of that Disco Volante vibe. I find it wears larger on the wrist than the 36 mm diameter, and is only 8 mm high (case+crystal). I purchased this in 2017 from a fellow OF member, but I have only worn it a handful of times since.
