VSF Yacht-Master 40 126655 Review: VS3235 Teardown & 129.6g Weight Test
Executive Summary (Direct Technical Answer): The VS Factory Yacht-Master 40 (Ref. 126655) features an 18K Everose gold-plated base case weighing exactly 129.6 grams on the rubber Oysterflex strap. It incorporates a bi-directional matte sandblasted Cerachrom ceramic bezel with raised polished numerals, an authentic “2WP” clasp batch engraving, and the proprietary DanDong VS3235 automatic movement offering an authentic 70-hour power reserve and clockwise calendar quickset.
The Rolex Yacht-Master 40 in 18K Everose gold (Ref. 126655 / 116655) represents an intricate convergence of high-contrast nautical aesthetics: a sandblasted matte ceramic bezel, warm rose-gold case metallurgy, and an elastomer-overmolded titanium strap assembly. In the replica watch segment, replicating precious-metal references presents distinct technical challenges—specifically regarding plating tone accuracy, total mass distribution, and bidirectional bezel ratcheting feedback.
This technical teardown objectively analyzes the VS Factory execution of Reference 126655, evaluating measured physical weight, micro-hallmark stamps, clasp tolerances, photoluminescence, and the kinematic architecture of the integrated DanDong VS3235 calibre.
1. Measured Physical Specifications & Tolerances

| Engineering Parameter | VS Factory Measured Specification | OEM Reference Benchmark |
|---|---|---|
| Case Dimensions | 40.0 mm Diameter / 11.5 mm Thickness | 40.0 mm / 11.5 mm |
| Total Weight (with Strap) | 129.6 grams (Measured on digital scale) | ~155.0 to 160.0 grams (Solid 18K Gold) |
| Bezel Insert | Bi-directional Matte Cerachrom Ceramic | Sandblasted Finish with Raised High-Gloss Numerals |
| Case Metallurgy | Multi-layer Everose Gold PVD over Base Alloy | Solid 18K Everose Gold (Au750) |
| Clasp Production Code | “2WP” Laser-etched Blade Inscription | Standard Factory Production Batch Marker |
| Movement Calibre | Custom DanDong VS3235 Automatic | 28,800 vph / ~70 Hours Power Reserve |
2. Physical Weight Benchmarking & Case Metallurgy
Replicating precious-metal timepieces requires balancing structural density against daily wearability. When measured on a calibrated precision digital scale, the VS Factory Ref. 126655 on its Oysterflex strap registers at exactly 129.6 grams.
Figure 2: Calibrated scale measurement confirming the assembled weight of 129.6 grams.
Because genuine 18K Everose gold possesses a specific gravity of approximately 15.5 g/cm³, solid precious-metal originals weigh between 155g and 160g on the Oysterflex configuration. The VS Factory model achieves 129.6g by utilizing high-density steel core architecture treated with an advanced multi-stage physical vapor deposition (PVD) gold application. The tone avoids excessive yellow or brassy hues, closely matching the proprietary warm copper-platinum hue of Everose gold.
3. Dial Typography, Matte Cerachrom Bezel & Photoluminescence
The dial layout features a high-gloss black lacquer base with contrasting red “YACHT-MASTER” script positioned centrally above the lower chronometer text. Micro-inspection reveals crisp typography registration without ink pooling or blurred letter edges.
Figure 3: Long-exposure capture of the Swiss Chromalight blue luminescent emission across indices and hands.
The applied hour markers are framed in rose-gold tone surrounds filled with Swiss Chromalight luminous compound. As shown in Figure 3, the luminescence emits a uniform 460 nm blue wavelength with consistent intensity across the hands, hour indices, and the triangular 12 o’clock marker.
The bi-directional rotating bezel utilizes a solid black Cerachrom ceramic insert. The background receives a fine micro-blasted matte treatment, against which the 60-minute graduations and raised Arabic numerals are polished to a high mirror gloss. The tactile bezel action operates on internal ball bearings, offering defined clicks with minimal rotational back-play.
4. Caseback Geometry, Triplock Crown & Micro-Hallmarks
The case flank demonstrates the signature curved profile of the Yacht-Master line, diverging from the flatter slab sides of the Submariner. The lateral surfaces are hand-polished to a high mirror finish.

The winding crown utilizes the Triplock triple-waterproofing system, identifiable by the three raised dots beneath the coronet logo. Screw-down action against the internal case tube threads is smooth and linear.

On the reverse side, the solid screw-down caseback displays fine concentric circular brushing framed by polished fluting. The underside of each lug incorporates deep laser-etched precious-metal hallmarks: the Swiss St. Bernard dog head, the balance scale emblem, and the Au750 purity marking.
5. Clasp Micro-Typography & ‘2WP’ Batch Identification
The watch is fitted with a flexible Oysterflex-style high-performance elastomer strap, supported internally by shape-memory titanium-nickel alloy blades. The underside incorporates longitudinal cushion ribs that stabilize the watch head on the wrist while facilitating airflow.

The Oysterlock safety folding clasp provides the 5mm 5-step Glidelock micro-extension system. High-magnification inspection of the inner clasp blade confirms crisp laser micro-engravings: ROLEX with coronet, GENEVA, SWISS MADE, 750, the scale hallmark, and the distinct factory batch code 2WP.
6. Internal Kinematics: DanDong Custom VS3235 Movement
The core mechanical differentiator of the VS Factory Yacht-Master 40 is the exclusive DanDong Calibre VS3235 automatic movement. Unlike modified 2824 or hybrid movements with decorative balance plates, the VS3235 is engineered with genuine 3235 gear train kinematics.
Technical Calibre Characteristics:
- Authentic 70-Hour Power Reserve: Utilizes an enlarged mainspring barrel architecture that delivers approximately 68 to 72 hours of uninterrupted autonomous operation.
- Correct Calendar Handset Operation: Winding the crown clockwise advances the hour hand and flips the date forward at midnight instantly, fully replicating genuine operation.
- Oscillation Rate: Regulated at 28,800 beats per hour (4 Hz) for a smooth 8-ticks-per-second central sweep second hand.
- Kinematic Reliability: Equipped with functional Paraflex-style shock absorbers over the balance wheel jewels, providing resilience against daily positional shocks.
