Gérald Genta Fantasy Retro RSF.X.10 Stainless Steel Case-Back
Overview
Original stainless steel case-back for the Gérald Genta Fantasy Retro RSF.X.10, a limited-production timepiece from the early 2000s. The Fantasy Retro series was part of Gérald Genta‘s collaboration with Disney, featuring licensed character designs on the dial while maintaining Swiss mechanical watchmaking standards. This case-back is marked with the official reference RSF.X.10, confirming its compatibility with the 40.5 mm Fantasy Retro models powered by automatic movements.
The case-back is crafted from 316L stainless steel, a corrosion-resistant alloy standard in Swiss watchmaking for its durability and hypoallergenic properties. The exterior features machine-engraved markings in the original Gérald Genta typography, including the Disney copyright notation, water resistance rating, and “Swiss Made” designation. The interior surface retains the factory finish, designed to interface with the movement holder and case gasket without modification.
This is a new-old-stock (NOS) service part, graded Excellent in our Condition Grading Scale below. No signs of installation, tool marks, or deformation are present. The article is sold as a standalone component—no gaskets, screws, or additional case parts are included unless explicitly stated. Intended for professional use in watch servicing or restoration, where original Gérald Genta parts are required to maintain collector value and functional integrity.
Specifications

Material: 316L stainless steel, brushed finish on the exterior with a matte interior surface for movement contact.

Engravings (exterior, radial layout):
G | AUTOMATIC | Fantasy retro | © Disney | (Genta catalog number) | RSF.X.10 | WATER RESISTANT | STAINLESS STEEL | SWISS MADE.
The “WATER RESISTANT” marking indicates a factory-rated resistance to 30 meters (3 ATM), typical for dress watches of this period. No serial numbers or individual identifiers are present—this is a generic service part for the RSF.X.10 series.
The case-back uses a six-notch design for case-back wrenches, compatible with standard Swiss watchmaking tools (e.g., Horotec or Bergeon). The interior recess includes a circular gasket channel for the original nitrile or silicone seal, though no gasket is included with this listing. Thread pitch and diameter conform to Gérald Genta‘s specifications for the Fantasy Retro line, ensuring direct replacement without case modification.
