Description
QF Factory Rolex Day-Date 36 Ref. 128398TBR Tungsten Heavyweight
The integration of a 155.1g tungsten-alloy case establishes a new tactile benchmark for 36mm precious metal replicas.
Powered by Clone Caliber 3255
The Clone Caliber 3255 represents a significant structural upgrade over legacy 2836-based Day-Date replicas. It features a true clone architecture that supports the correct hour-minute-second hand stack and instantaneous calendar jumps at midnight. Regulated via a traditional index system, the movement operates at 4Hz (28,800 vph) and has been evaluated against to ensure reliable daily performance. The rotor is designed to mimic the genuine winding feel, though it may exhibit slightly more audible feedback during rapid wrist movement.
卤10��15 seconds per day. This is standard for non-Dandong 3255 clone calibers, relying on traditional regulation rather than free-sprung balances.
- �� Power Reserve: Approximately 36 hours
- �� Complications: Center hours, minutes, seconds; instantaneous day and date with unrestricted rapid-setting.
- �� Winding Direction: Bidirectional
Technical Specifications
Measuring 36mm in diameter and precisely 12mm thick, the case utilizes a heavy tungsten core to achieve 155.1g. Finished with 18k yellow gold plating and brushed lug hoods.
Each dial exhibits unique organic iridescence. Features crisp typography and synthetic diamond hour markers, though coronet depth may vary slightly from genuine.
Stones are uniform in size and clarity, securely prong-set into the 18k gold-plated frame, mirroring the factory gem-setting layout of the 128398TBR.
Semi-circular three-piece links featuring polished center sections. Includes ceramic inserts within the pins to prevent premature stretch over time.
Why QF Factory for This Reference?
Many collectors ask: ��Why not GMF?��
While GMF pioneered the tungsten heavy-case movement for Day-Dates, QF��s recent 155.1g batch offers superior weight distribution. By concentrating the tungsten mass more evenly across the case mid-section and caseback, the QF version mitigates the top-heavy wrist feel that plagued earlier heavyweight replicas, ensuring the watch sits flat against the wrist.
Full Disclosure: The 18k yellow gold plating, while visually accurate under natural light, lacks the deep, warm metallurgical luster of solid gold under harsh artificial lighting, and the clasp mechanism exhibits slightly more lateral play than genuine.

Collector Q&A
Q: How does the 155.1g weight compare to the genuine solid gold Day-Date 36?
A: The genuine 18k gold Day-Date 36 weighs approximately 160-170 grams depending on the number of bracelet links installed. At 155.1 grams, the QF tungsten-enhanced version is within 10-15 grams of the genuine, providing a virtually identical tactile experience on the wrist compared to standard 115g steel replicas.
Q: Are the diamonds on the bezel and dial genuine?
A: No. The stones used on the bezel and dial are high-quality synthetic crystals (typically cubic zirconia or moissanite). While they offer excellent light refraction and clarity under natural light, they will not pass a professional diamond tester.
Q: Does the day and date mechanism function like the genuine caliber?
A: Yes. The Clone 3255 movement features an instantaneous flip for both the day and date apertures at midnight, rather than a slow, gradual roll over several hours. It also supports unrestricted rapid-setting via the crown.
Q: Will the 18k yellow gold plating fade or tarnish over time?
A: While QF utilizes an advanced PVD plating process for durability, it remains a surface treatment over a steel/tungsten base. High-friction areas, particularly the underside of the President bracelet and the Crownclasp, will eventually show signs of wear or fading with regular daily use.
