Dandong 3285 Movement · Precision-Driven Structural Accuracy

The latest VS Factory GMT-Master II “Pepsi” marks a comprehensive implementation of the Dandong 3285 integrated GMT movement, bringing the project closer to modern engineering standards rather than surface-level resemblance.

This release focuses on movement functionality, bezel material response, optical clarity, hand geometry, crown structure, and overall thickness control, following the development logic of the modern Rolex GMT-Master II.

1. Dandong 3285 Integrated GMT Movement

VS Factory equips this model with the advanced Dandong 3285 integrated automatic GMT movement, featuring a true independent jumping local-hour hand and reverse quick-set date function.
Compared with modular or assembled GMT solutions, this integrated architecture offers superior functional logic, stability, and long-term usability.

2. V3 Pepsi Bezel · UV Reaction Accuracy

The VS V3 Pepsi bezel displays a red reaction under ultraviolet light, matching the genuine reference behavior.
This UV response is a key indicator of correct bezel material composition and pigment formulation—an area where many market versions fail under comparison.

3. High-Transparency Sapphire Crystal

VS uses a high-clarity sapphire crystal comparable to the original specification, with controlled reflections and minimal edge distortion.
Light refraction across the crystal remains subtle and clean, avoiding the excessive glare and reduced transparency commonly seen in other market versions.

4. Cyclops Magnification & Coating

The date magnification ratio is among the closest to genuine proportions currently available.
The anti-reflective coating presents a white-pink tone consistent with the original, rather than the blue tint often seen on over-magnified market alternatives.

5. Bezel Teeth Geometry

Bezel teeth size and spacing are developed to match original proportions, ensuring both correct visual scale and natural rotational feedback.
Many market versions enlarge the teeth for easier grip, resulting in inaccurate appearance and feel.

6. Crown Locking Structure

When fully screwed down, the crown retains a 0.25mm structural gap, identical to the genuine design.
This clearance reduces friction between the crown and case, minimizing wear over time. Market versions often eliminate this gap, causing direct contact and potential case abrasion.7.

Hand Shape & Color Accuracy
• The minute hand features a sharp, pointed profile
• The seconds hand is straight and clean, without bending or blunt finishing
• The GMT hand uses a bright red tone, consistent with the genuine reference

In contrast, many market versions use darker red GMT hands with less refined hand geometry.

7. Correct Thickness Control

The overall case thickness is controlled at approximately 12.1mm, matching the genuine specification.
By comparison, many alternative versions measure around 12.5mm—an excess of 0.4mm that becomes visually apparent from side profile inspection.

8. Structural Accuracy Through Verifiable Details

Rather than relying on marketing language, the VS Factory GMT-Master II “Pepsi” is built around measurable, comparable, and verifiable details.
From movement architecture to optical behavior and structural clearances, this model reflects the real meaning of full-mold development—details that withstand direct comparison.

FAQ | Frequently Asked Questions

1. Does this GMT support an independent jumping hour hand?
Yes. The Dandong 3285 movement supports an independent local-hour jump and reverse date adjustment.

2. What is special about the V3 Pepsi bezel?
Under UV light, the bezel displays the same red reaction as the genuine reference, indicating correct material formulation.

3. Is the crystal and cyclops accurate?
Yes. The crystal offers high transparency with controlled reflections, and the cyclops magnification and coating closely match genuine proportions and tone.

4. Is the thickness correct?
Yes. The case thickness is approximately 12.1mm, consistent with genuine specifications.

5. Is it suitable for daily wear?
Yes. With accurate proportions, balanced thickness, and stable movement performance, it is well suited for everyday use.
