VS Factory Rolex Explorer I 40mm 224270 Dandong 3230 Review

Representing Rolex's exploration and climbing heritage, the Explorer collection was introduced after years of 36 mm and 39 mm case discussions, Ref. With 224270, it finally gained a 40 mm case architecture that fits modern wrist sizes perfectly. In this version, powered by the Dandong 3230 integrated mechanism that VS Factory produced from scratch instead of decorative fake bridges; We examine the deep black enamel layer on the dial, the optical symmetry of the numbers 3-6-9 and the weight balance of the new case profile on the wrist.

1. 40mm Case Breakthrough and Wrist Balance Expected After 36mm

The Explorer I series, produced by Rolex in memory of the 1953 Everest climb, is the cornerstone of sports watches with its minimalist dial and extremely robust structure. For watch enthusiasts who find the classic 36mm case size small or want a more prominent presence on the wrist, Rolex will introduce the 40mm Ref. It announced the 224270 model. VS Factory has presented this model, equipped with the Dandong 3230 caliber, with the highest level of workmanship in the clone market.

Caliper measurements recorded a clear diameter of 40.0 mm and a thickness of 11.5 mm. It is millimetrically compatible with the original model. There are brushed satin lines on the upper surface of the lugs and mirror-polished polishing on the case cheeks. The Twinlock screw-down crown provides full protection against dust and water in daily use with its double O-ring waterproofing seal.

3. Deep Lacquered Black Dial and Iconic 3-6-9 Numeral Typography

5. VSF Dandong 3230 Integrated Caliber and Ghost Stage Cancellation

In ordinary replicas, the date of the 3235 movement is hidden, leaving a 'ghost cascade' (empty crown pull). On the Dandong 3230, the crown only winds winding in the 1st stage, and directly sets the time in the 2nd stage; The empty click has been completely eliminated.

6. 70 Hours Continuous Power Reserve and Mechanical Stability
