⚠ Function Disclosure — Read Before Purchasing
The PPF 6102P is built on a two-hand Shanghai Cal.240 base movement without a complications module. The celestial functions behave differently from the genuine reference in the following ways:
- Star chart (lower crown): Rotates the sky disk manually in both directions. The disk is mechanically independent from the movement — it does not self-advance with timekeeping. Both crown rotation directions control the same sky disk.
- Moon phase: The moon phase indicator is mounted directly to the date wheel and advances once per calendar day alongside the date. It does not follow the genuine 29.5-day lunar cycle, and does not produce the gradual waxing and waning effect of the original.
- Lower crown linkage: The lower crown does not interface with the movement caliber. Pressing the case-side date correction buttons advances both the date and moon phase indicator simultaneously.
- Case markings: The case is stamped PT950. The fold-over clasp carries an AU750 mark — an inconsistency present across the current production run.
This reference is recommended for collectors drawn to the visual architecture of the 6102P — the three-layer sapphire dial, correct case profile, and dial depth — rather than functional complication accuracy.
Movement — Shanghai Cal.240 Two-Hand Base
The PPF 6102P runs on a Shanghai-manufactured Cal.240-based automatic caliber in a two-hand configuration. The movement bridges carry perlage and côtes de Genève decoration visible through the exhibition caseback. The rotor is a full central winding rotor rather than the micro-rotor of the genuine Patek movement — this architectural difference is visible under loupe inspection through the caseback.
The movement drives timekeeping and date functions reliably. The celestial disk and moon phase display are separate assemblies mechanically independent of the caliber — the movement does not drive either complication.
⏱ Accuracy Profile:
±10–15 s/day. Consistent with the Shanghai 240 base caliber under normal wear conditions.
- ✅ Power Reserve: Approximately 36 hours
- ✅ Upper Crown: Time-setting and manual winding — fully functional
- ⚠ Lower Crown: Manually positions star sky disk only — no movement linkage
- ⚠ Moon Phase: Calendar-indexed display — advances daily with date, not by lunar cycle
What PPF Got Right — and Why the Functions Were Simplified
The dimensional accuracy of the PPF 6102P is genuine: previous factory attempts at this reference produced cases exceeding 12.5mm to accommodate a gearing module, making them visually distinct from the genuine. PPF resolved this by using a two-hand base movement without a complications layer, achieving the verified 10.5mm profile.
The trade-off is functional: replicating the genuine 240 base with its independent celestial module requires machining tolerances that Shanghai movement manufacturing cannot reliably produce at volume — and even the genuine Patek movement requires careful hand-fitting of the module to avoid gear mesh errors during assembly. A fully functional version produced to this standard would carry a substantially higher price point.
This piece is the correct choice for a collector who wants the visual presence and case architecture of the 6102P on the wrist. It is not the correct choice for a collector who wants the lower crown to interact with the movement.
Collector Q&A
Q: Does the star chart rotate automatically as time passes?
A: No. The sky disk is mechanically independent from the movement. It is positioned manually using the lower crown and holds its position. It does not advance with timekeeping. This differs from the genuine reference, where the star chart is driven by the movement and rotates in sync with sidereal time.
Q: What does the lower crown actually do?
A: Rotating the lower crown in either direction manually repositions the star sky disk. It does not interface with the movement caliber. On the genuine 6102P, the two crown directions serve different functions — clockwise for moon phase, counter-clockwise for sky chart — and both are linked to movement-driven modules. The PPF version uses the lower crown solely to physically rotate the sky disk.
Q: How does the moon phase behave compared to a genuine moon phase complication?
A: The PPF moon phase indicator is mounted to the date wheel and advances once per calendar day alongside the date. It does not track the 29.5-day lunar cycle and does not produce the gradual waxing and waning progression of a genuine moon phase complication. Pressing the case-side date correction button will advance both the date and the moon phase indicator simultaneously.
Q: Is the case made of solid platinum like the genuine 6102P?
A: No. The case is 316L stainless steel, polished to match the luster of the genuine platinum reference. The case carries a PT950 stamp; the fold-over clasp is marked AU750. The 87g total weight reflects steel construction — significantly lighter than the genuine platinum piece.
Q: Who is this reference suitable for?
A: The PPF 6102P is the correct choice for collectors drawn to the visual architecture of this reference — the three-layer sapphire celestial dial, the correct 10.5mm case profile, and the overall wrist presence of the grand complication format. Collectors who require the lower crown and celestial functions to operate as the genuine movement drives them should be aware of the differences outlined above before purchasing.
