Datejust 31 Super Clone

GS Factory Edition — Jubilee Bracelet

The Rolex DateJust 31 Ref. 278384RBR represents a specific horological niche, and GS Factory has established itself as the primary manufacturer for this mid-size platform. While tier-one factories often prioritize 36mm and 41mm models, this release delivers a specialized 31mm case architecture with correct gem-set bezel proportions.

Powered by the clone 2236 caliber, this movement is specifically scaled down to fit the 31mm case without relying on oversized spacer rings. It operates with a bidirectional winding module and, in accordance with current replica movement constraints, yields approximately 36 hours of power reserve. The integration of the 2.5x Cyclops lens over the instantaneous date mechanism functions crisply.

Forged from 904L Oystersteel, the case measures exactly 31mm in diameter with a verified thickness of 11.2mm, matching the genuine profile. The forest green dial exhibits a sunburst finish that responds well to ambient light, paired with a simulated diamond-set bezel that captures the essence of the RBR designation.

• Movement: Clone 2236 Caliber — Approximately 36 hours
• Case Material: 904L Oystersteel, 31mm diameter, 79g overall weight
• Bezel: Simulated gem-set (CZ), visually accurate to standard lighting
• Crystal: Sapphire with 2.5x Cyclops magnification
• Bracelet: 904L Jubilee, alternating brushed/polished, Folding Oysterclasp
• Water Resistance: 50 Meters — professional pressure test recommended before swimming

Designed for collectors seeking a mid-size profile, this piece balances elegance with robust 904L construction. It serves as an excellent daily wearer for smaller wrists where traditional 36mm cases feel overwhelming.

GS Factory Edition — Jubilee Bracelet

The 31mm mid-size Datejust occupies a specific niche in horological replicas, and GS Factory’s execution of the reference 278383RBR addresses the historical lack of high-tier options in this diameter. By integrating a dedicated clone 2236 architecture, this edition maintains the correct case proportions and crown position without the thickness bloat often seen in modified ETA-based alternatives.

Driving the hands is the mechanical self-winding Clone 2236 caliber, designed to replicate the operational feel of the genuine movement. It features a stop-seconds mechanism for precise synchronization and an instantaneous date complication. Power delivery is linear, yielding a practical reserve suitable for regular rotation.

The two-tone Oystersteel and 18k yellow gold-plated case measures exactly 31mm, paired with a meticulously aligned diamond-set bezel. The dial features an olive green tone that accurately shifts under varying light conditions, viewed through a sapphire crystal with a correctly magnified Cyclops lens.

• Movement: Clone 2236 — Approximately 36 hours
• Case Material: Oystersteel with 18k yellow gold plating, 31mm diameter
• Bezel: Diamond-set bezel, precise CNC prong alignment
• Crystal: Sapphire with 2.5x magnification Cyclops lens
• Bracelet: Two-tone Jubilee, Folding Oysterclasp
• Water Resistance: 50 Meters — professional pressure test recommended before swimming

This reference is tailored for collectors seeking a mid-size profile with gem-set characteristics. It serves as a highly capable mechanical alternative for formal settings where a 36mm or 41mm case would be disproportionate.
