Overview

The ETA 2893-2 is a self-winding movement that powers the watch through the natural motion of the wearer. As the rotor spins, it winds the mainspring, delivering a power reserve of approximately 42 hours when fully wound. This ensures reliable operation even when the watch is not in constant use.

Renowned for its precision, durability, and versatility, the 2893-2 features both a GMT function and a date display, allowing users to track multiple time zones while keeping an eye on the date. Its robust construction and proven reliability make it a popular choice among watchmakers and enthusiasts who value both functionality and craftsmanship.
