Editor’s Comment:

Not many brands can draw upon the history that Eterna has, and certainly not many brands can boast having an in-house movement. What is strange is that as of 2023, Eterna’s line of watches mostly consists of Sellita based movements. For example, the 1948 Sunbrush Automatic 40mm has a Sellita caliber SW300-1, and the Eternity for Him Automatic 40mm is powered by a caliber SW200-1 – not to mention their other pieces with ETA quartz movements. Where are all of the in-house movements and why wouldn’t they base their brand upon them. It appears to be yet another example of a watch brand without purpose or direction, attempting to fulfill this outdated need to produce too many different models. The watch industry (especially the Swiss based companies) have not yet caught on to the concept that less is more – especially when your “less” has a lot more to offer than the competition. In-house for $3k makes it a brand worth looking at. Unfortunately that gets watered down because of the other items on the menu.
