Eterna has always been a watch brand that I’ve liked, and I have owned several over the years, hoping that one day they would again create something as innovate as the ball bearing rotor and again revolutionalize the watchmaking world. They have just announced their new Spherodrive movement, the in-house Caliber 3505, which uses a brand new ball-bearing mounted spring barrel. While Eterna has begun manufacturing and designing their own movements in-house, they have not hung back and simply re-invented the wheel, with many of their new designs they are incorporating new ideas and new ways of helping us tell time. Eterna is poised to be another Watchmaking powerhouse – at least I think so.. but I’m biased since I’ve always had a soft spot for the brand.

The New Eterna Madison with Spherodrive uses a modified 3500 movement with the new ball-bearing mounted barrel, and measures 35x 38mm. The watch has a Sapphire crystal front and back, and is water resistant to 50m.
