Description
Patek Philippe Nautilus 5811/1G-001: The 3KF “New Clasp” Edition
The successor to the throne. Featuring the new 41mm White Gold Style Case and the upgraded Micro-Adjustment Clasp.
⚠️ Important Technical Notice: Caliber 324 vs. 330
We believe in total transparency. The genuine 5811 utilizes the newer Caliber 26-330 S C (which features a hacking/stop-seconds function). However, the replica industry (including 3KF) currently ONLY produces the Super Clone 324 movement.
What this means for you: Even though the movement bridges are correctly engraved with “26-330” to visually match the genuine, the internal mechanism is still the ultra-thin Clone 324. Therefore, the watch functions like the classic Nautilus: The seconds hand does NOT stop when setting time. This is normal behavior for this clone movement and ensures the watch maintains its ultra-thin profile.
Why the 3KF 5811?
The 5811 is not just a larger 5711; it’s a complete refinement. 3KF has captured the subtle differences that distinguish this White Gold masterpiece.
- ✅ The New Clasp System: Finally, a Nautilus with adjustment! 3KF has replicated the new fold-over clasp with a lockable micro-adjustment system, allowing you to expand the bracelet by 2-4mm for comfort.
- ✅ 41mm “Jumbo” Size: True to the new reference, the case diameter is 41mm. The two-piece case construction aesthetic pays homage to the original 1976 Nautilus.
- ✅ Sunburst Blue-Black Dial: The 5811 features a richer, darker blue peripheral gradient than the 5711. 3KF’s dial captures this “White Gold Exclusive” hue perfectly.
Technical Specifications
8.3mm Ultra-Thin
Despite the size increase to 41mm, 3KF maintains the razor-thin 8.3mm profile, ensuring it remains the most elegant sports watch on the market.
White Gold Tone
Constructed from 316L Stainless Steel but finished to mimic the high-sheen luster of 18k White Gold. The bezel features vertical brushing and mirror-polished bevels.
Clone 324 (Visual 330)
Engraved as “26-330 SC” to match the transparent caseback view. The rotor is silent, and the finishing includes Côtes de Genève and perlage.
Patented Micro-Adjust
The game-changer. A secure fold-over clasp with a dedicated adjustment mechanism on both sides, solving the “too tight/too loose” issue of the 5711.
