Hyper Clone Explorer I 36mm vs 39mm: Which Factory Does It Best?
The ultimate stealth Rolex demands absolute symmetry and flawless dial execution. We break down the battle between Clean Factory and BP Factory across both classic sizes.
For collectors, the primary debate revolves around size: the historically accurate 36mm (Ref. 124270) versus the modern, discontinued 39mm (Ref. 214270). Executing either of these correctly requires an exact command of 904L steel case finishing. In 2026, the landscape for both sizes is fiercely contested by Clean Factory (CF) and the legacy BP Factory (BPF).
The “Ghost Position” Warning
Because the Explorer I does not have a date window, the crown should only have two positions: winding and time-setting. Lower-tier clones use standard movements with a hidden date gear, resulting in a phantom “click” when you pull the crown. Top-tier factories use dedicated no-date movements to eliminate this tell entirely.
The 36mm Benchmark (Ref. 124270)
When Rolex returned the Explorer to its classic 36mm roots, Clean Factory completely dominated the replication process. Clean entirely re-engineered their case tooling to ensure the 19mm lug width tapers down perfectly to the clasp. This taper is critical to the vintage feel of the watch, and lesser factories often make the lugs too wide and blocky.
Inside, Clean Factory utilizes the VR3230 movement. As highlighted in our dedicated clone calibre accuracy guide, the VR3230 is a true no-date movement. It operates flawlessly without the dreaded ghost position and provides excellent amplitude and reliability. When inspecting the dial, Clean’s pad-printing process ensures the “EXPLORER” text is perfectly crisp, and the white gold surrounds on the 3-6-9 markers are smoothly rounded without rough edges.
The 39mm Heavyweights (Ref. 214270)
The 39mm Explorer I is a favorite for those with wrists over 7 inches. For years, BP Factory (BPF) was the community’s go-to choice for this model, offering incredible value and a highly accurate ‘Mark II’ dial (where the 3, 6, and 9 numerals are fully filled with blue lume). However, BP Factory’s Achilles’ heel has always been their steel brushing, which feels slightly rougher than premium models.
In 2026, Clean Factory stepped into the 39mm arena and effectively took the crown. Clean uses verifiable 904L steel with industry-leading brushing that surpasses BP’s finish. Their Oyster bracelet articulates beautifully, and the smooth bezel reflects light with a mirror-like perfection. While BP remains a fantastic budget option, Clean Factory is the only choice for a true 1:1 illusion.
| Specification Component | Clean Factory (36mm) | Clean Factory (39mm) | BP Factory (39mm) |
|---|---|---|---|
| Case Steel | Verified 904L Steel | Verified 904L Steel | 316L (or lesser 904L finish) |
| Movement | VR3230 (No Ghost Position) | VR3132 (No Ghost Position) | A2824 or SA3132 (Ghost position possible) |
| Bracelet Finish | Excellent articulation, smooth edges | Excellent articulation, smooth edges | Good, but slightly stiff/sharp edges |
| Dial Crispness | Flawless 3D text printing | Razor-sharp indices and text | Great, but occasionally flat printing |
Because the Explorer’s design is so naked, any scratch or misaligned marker during shipping is devastating. Always review your agent’s photos through a strict arrival QC and verification protocol. Ensure the 12 o’clock triangle is perfectly centered and the lume application is entirely even across all indices.

The Authority Verdict
If you demand the absolute best Explorer I in 2026, Clean Factory is the undisputed winner for both the 36mm and 39mm references. Their mastery of the no-date movement architectures, combined with unparalleled 904L steel brushing, elevates their pieces to true hyper clone status. BP Factory remains a respectable budget alternative, but Clean delivers the flawless symmetry this watch demands.
Frequently Asked Questions
Which factory makes the best Explorer I 36mm in 2026?
Clean Factory (CF) is currently the undisputed leader for the 36mm Explorer I (Ref. 124270). They perfectly capture the elegant lug tapering and utilize the highly reliable VR3230 no-date clone movement.
Who makes the best 39mm Explorer I?
For the 39mm (Ref. 214270), BP Factory (BPF) has historically offered the best value, but Clean Factory recently overtook them by offering superior 904L steel finishing and a much smoother Oyster bracelet.
Is the dial simple to clone?
Deceptively no. Because there is no date window, cyclops, or busy bezel to distract the eye, the dial must be flawless. The 3-6-9 white gold surrounds must be perfectly rounded, and the pad-printed text must be razor-sharp to pass a loupe inspection.
What movement is inside the Clean Factory Explorer I?
Clean Factory utilizes the VR3230 for the 36mm and the VR3132 for the 39mm. Both are dedicated ‘no-date’ clone movements, which means there is no phantom ‘click’ or dead position when pulling out the crown, operating exactly like the genuine pieces.
Does the 36mm Explorer clone taper correctly at the lugs?
Yes. Clean Factory entirely re-engineered their case tooling for the 124270 to ensure the 19mm lug width tapers down perfectly to the clasp, maintaining the classic vintage proportions of the 36mm case without looking blocky.
Is the lume accurate on these clones?
Yes, top-tier factories use high-quality Chromalight-style blue lume that glows intensely. Importantly, they ensure the 3-6-9 numerals are fully lumed, correctly matching the modern ‘Mark II’ dial specifications of the genuine Explorer.
Should I choose the 36mm or the 39mm?
This depends entirely on your wrist size and stylistic preference. The 36mm is the classic, historically accurate size that slides perfectly under a cuff. The 39mm offers a more modern, sporty wrist presence suited for those with wrists over 7 inches.
Is the steel finishing on BP Factory as good as Clean Factory?
No. While BP Factory is excellent for the price, Clean Factory uses verifiable 904L steel with vastly superior brushing and edge chamfering, making it the definitive choice for those seeking true hyper clone structural accuracy.
