Description

GERALD GENTA Gefica GBS.Y.98 Bronze and Titanium Watch Case

Overview

GERALD GENTA was a Swiss watchmaker renowned for designing iconic timepieces, including the Royal Oak for Audemars Piguet and the Nautilus for Patek Philippe. The Gefica series, introduced in the late 1990s, was part of GERALD GENTA‘s independent collections, characterized by bold designs and high-end materials. This is an original GERALD GENTA Gefica watch case in bronze and titanium, designed for professional servicing or restoration.

The case is made from solid bronze with titanium elements, measuring approximately 46.5 mm in diameter. The bronze will develop a natural patina over time, resulting in unique color variations and darker spots. The case includes the crystal, bezel, crown, and screw-down case-back. No screws are provided. The case is unused and graded Excellent in our Condition Grading Scale below.

This is a full case kit intended for watchmakers and collectors requiring authentic replacement parts. The case-back is screw-down, ensuring water resistance to 10 ATM (100 meters). The GERALD GENTA logo, material markings, and reference number are engraved on the case-back.
