Eterna Madison with Spherodrive

Eterna Madison with Spherodrive

At first glance, this timekeeper aligns with few classic styled pieces, but a little more examining view will reveal the true capabilities of this tonneau-shaped watch, an immensely impressive 8 days power reserve. Due to an innovative mechanism, called the Spherodrive, the Eterna caliber 3510 achieves to reduce friction loss, and the steadily diminishing amount of energy when the springs uncoil. This Swiss haute horological achievement coupled with timeless, classic appearance is definitely among the most resolute statements a wristwatch can offer.
