The Rolex Datejust 126334 is one of those watches where overall design is relatively simple, but accuracy depends heavily on small details. The fluted bezel, Cyclops magnifier, sunburst dial, Jubilee bracelet, rehaut engraving and movement all need to work together for the watch to look convincing.

Both Clean Factory (CF) and VS Factory (VSF) are well-known for producing higher-tier Datejust replicas. Clean Factory does several things extremely well, so this is not a one-sided comparison. However, after comparing the two across the areas below, our overall preference is VS Factory.

1. Dial & Printing

Both factories produce a strong Datejust dial, especially when viewed at normal wrist distance. Clean Factory has good color presentation, clean markers and generally convincing proportions.

Under closer inspection, however, we give VSF a slight advantage. The Rolex coronet, dial lettering and smaller lines of text tend to look more balanced and consistent. Marker placement and the relationship between the minute track and applied indices also give the VSF dial a slightly more refined appearance.

The difference is small, but when macro photographs are placed side by side, VSF looks more consistent to us.

Winner: VS Factory

2. Date Window & Cyclops

The Datejust’s date display is one of the easiest details to notice because of the prominent Cyclops lens at 3 o’clock.

Clean Factory performs well here, but the VSF crystal and Cyclops combination is one of the main reasons we prefer VS Factory on the Datejust.

On the VSF version, the date appears clear and appropriately enlarged through the magnifier, while the window itself looks neatly integrated into the dial. Alignment and visual clarity are especially important because even a slightly unusual magnification can immediately change the appearance of a Datejust.

Clean remains competitive, but VSF gets our vote for the crystal and Cyclops presentation.

Winner: VS Factory

3. Fluted Bezel

The fluted bezel is arguably the signature component of the 126334.

Both factories reproduce its alternating polished surfaces well, and this is one category where the difference can depend heavily on the exact batch and lighting conditions.

Clean Factory’s bezel can look very sharp, particularly in bright lighting. VSF, however, gives us a more balanced overall impression when the bezel is viewed together with the crystal and case.

The individual flutes appear clean and well defined, with consistent reflections around the circumference. We also like the way the bezel transitions into the case on the VSF example.

This is one of the closest categories in the comparison.

Winner: VS Factory — by a small margin

4. Jubilee Bracelet & Case Finishing

The Jubilee bracelet has a major influence on how a Datejust feels in the hand and on the wrist.

Clean Factory produces a very respectable bracelet with good articulation and an attractive mixture of brushed and polished surfaces.

VSF also performs strongly, but we find its overall combination of bracelet fit, case finishing and transitions between polished and brushed surfaces slightly more convincing.

Look especially at the end links where the bracelet meets the case. Tight fitment and controlled finishing make the complete watch look much more premium than evaluating the bracelet alone.

For us, Clean feels more cohesive as a complete package.

Winner: Clean Factory

5. Rehaut Engraving & Small Details

The engraved rehaut is not something most people will notice from across the room, but it matters in a detailed factory comparison.

Both Clean and VSF include the repeating Rolex engraving around the inner ring, along with the coronet around 12 o’clock.

Under magnification, we prefer the depth, consistency and overall presentation of the Clean engraving. Alignment relative to the dial markers also looks convincing on a good VSF example.

This category demonstrates why QC photographs remain important even when choosing a respected factory. Small alignment differences can still exist from one individual watch to another.

Winner: Clean Factory

6. Movement

Movement choice is perhaps the most important technical difference when comparing these two Datejust options.

Both factories aim to provide the familiar functionality and feel expected from a modern automatic Datejust, but VSF’s movement execution is one of its strongest selling points.

In our view, VSF delivers the more complete package when movement feel, winding action, crown operation and overall integration are considered alongside the external construction.

That does not automatically mean every VSF movement will perform perfectly or never require servicing. Any mechanical watch can require maintenance. But when choosing between these two versions specifically, movement execution is another area that pushes us toward VSF.

Winner: VS Factory

Clean Factory vs VSF: Our Overall Comparison

Clean Factory remains a strong option. In fact, someone buying a CF Datejust is unlikely to receive a watch that suddenly looks obviously inferior. The differences we’re discussing are mostly the small details that become apparent when two high-grade versions are examined directly beside each other.

Clean Factory does especially well with overall construction, dial appearance and exterior finishing. In certain batches or configurations, some buyers may even prefer specific CF components.

However, when we consider the complete watch rather than choosing the best individual component from each factory, VS Factory feels more consistent to us.

Its dial execution, Cyclops presentation, bracelet integration, rehaut detailing and movement combine into a more convincing overall Datejust package.

Our Verdict: VS Factory Wins

If we had to choose only one between Clean Factory and VS Factory for the Rolex Datejust 126334, we would choose VS Factory (VSF).

The gap is not massive, and Clean Factory remains a serious competitor. But from our perspective, VSF delivers the better overall balance of visual accuracy, finishing, crystal/Cyclops quality, movement execution and consistency.

🏆 Overall Winner: VS Factory (VSF)

For buyers comparing these two factories, we would still recommend checking the actual QC photographs of the individual watch before approving it. Factory reputation matters, but alignment, finishing and smaller cosmetic details can still vary between individual pieces.
