Vintage 1950s Tropical Eterna Bumper

This 1950s Eterna combines mid-century Swiss craftsmanship with the warm character of an aged tropical dial. Powered by an early bumper-style automatic movement and housed in a slim 30.8 mm stainless steel case, it features Arabic numerals, gold-tone leaf hands with vintage patina, and an original domed crystal. A compact, characterful daily piece for collectors of vintage Eterna and bumper-era automatics.

Highlights

• Bumper-era automatic — first-generation Swiss self-winding architecture
• Tropical brown patina dial with Arabic numerals — desirable vintage evolution
• Compact 30.8 mm stainless steel case, period-correct silhouette
• Original acrylic crystal with minor wear
• Caseback engraved with serial 2887614

Bumper-Era Swiss Automatic

The watch is powered by an early bumper automatic movement — a transitional Swiss self-winding architecture that pre-dates the rotor-based automatics that became standard in later decades. The movement runs accurately on the wrist, though a service is recommended for optimal long-term performance. The crown operates smoothly for winding and time-setting.
