Description
8F Factory Audemars Piguet Royal Oak Selfwinding 34mm 77351ST.ZZ
8F Factory delivers a technically proficient 34mm execution, balancing an intricately gem-set bezel with reliable automatic mechanics.
Driven by Calibre 3120 Clone
The mechanical core of this 34mm Royal Oak is a robust automatic base movement, extensively modified by 8F to mirror the architecture of the Audemars Piguet Calibre 3120. The factory has applied decorative C么tes de Gen猫ve finishing across the bridges and installed a custom 22K gold-toned rotor, complete with the AP family crest. While not a ground-up free-sprung clone, this decorated caliber provides smooth sweep seconds and reliable daily performance, all verified through prior to dispatch.
卤10��15 seconds per day (Standard for decorated automatic base movements).
- �� Power Reserve: Approximately 36 hours
- �� Complications: Hours, minutes, center sweep seconds, and quick-set date at 3 o��clock
- �� Winding Direction: Bidirectional automatic winding
Construction & Specifications
The 34mm case is machined to precise tolerances, featuring the critical brushed and polished alternating finishing. The lug-to-lug profile is optimized for smaller wrists while maintaining the sharp, angular geometry characteristic of the Royal Oak lineage.
The dial exhibits the classic Grande Tapisserie texture, with cleanly stamped squares and precise concentric texturing. Applied hour markers and hands are treated with luminous compound for low-light visibility.
The iconic octagonal bezel is set with high-grade synthetic diamonds, secured via traditional setting techniques rather than adhesive. The eight hexagonal white gold-toned screws are properly aligned and polished.
Constructed from solid 316L steel, the integrated bracelet features a smooth taper and flexible links. The AP folding clasp operates with crisp tension, ensuring secure closure without excessive endplay.
Why We Selected 8F Factory
Collectors frequently ask: ��Why not BF Factory?��
While BF produces commendable mid-size Royal Oak models, 8F Factory currently offers superior tapisserie dial stamping and a more refined execution of the diamond-set bezel on the 77351ST reference. The alignment of the synthetic stones and the finishing of the integrated bracelet fit give the 8F version a distinct tactile advantage.
Worth Noting: The added decorative plates on the movement base can result in slightly more audible rotor bearing noise compared to the genuine Calibre 3120.

Collector Q&A
Q: Are the diamonds on the 8F 77351ST bezel real?
A: No, the 8F factory utilizes high-grade synthetic stones (cubic zirconia), meticulously handset into the 316L steel bezel to simulate the light refraction of genuine factory diamonds.
Q: How does the 34mm case wear compared to the 37mm 15450ST?
A: The 34mm case features a significantly shorter lug-to-lug profile, making it ideal for wrists under 6.5 inches while maintaining the signature angular Royal Oak presence and integrated bracelet fit.
Q: Is the Calibre 3120 clone in this model a true 1:1 free-sprung movement?
A: No, it is a heavily modified and decorated base movement designed to visually resemble the AP Calibre 3120. It features custom bridges and a 22K gold-toned rotor, prioritizing reliability over 1:1 mechanical architecture.
Q: Is the rotor noise noticeable on the 8F Calibre 3120?
A: Yes, as with many decorated clone movements, the added mass of the custom rotor plates can cause slight audible bearing noise in quiet environments during vigorous wrist movement.
