The PPF Nautilus 5711/1A is the best fake to buy first. It gets the two details that matter most right: a 40mm case that measures 8.5mm to 8.8mm thick, and a blue sunburst dial with the correct horizontal grooves. Expect to pay $480 to $700 depending on movement and seller.
Below is how that build compares with the 3K, PF, and SWF versions, plus the checks that separate a wearable replica from a paperweight.
Why the PPF 5711/1A takes first place
PPF worked from a scanned case instead of a photo, and it shows at the edges. The bezel bevel catches light the way the original does, and the caseback sits flush against the wrist.
The bracelet is the real reason to start here. Each link is brushed on top and polished on the sides, and the taper toward the clasp follows the genuine 5711 line.
- Case: 40mm steel, 8.5mm to 8.8mm thick
- Dial: blue sunburst, applied baton markers, lume that matches in daylight
- Movement: clone 324 SC or Miyota 9015 with a decorated rotor
- Bracelet: single-fold clasp, correct link count
- Weak spot: the date font runs a touch wide on older batches
How the four builds compare
All four run the same outside dimensions. The gaps show up in finishing, movement, and how the bracelet feels after a full day on the wrist.
- PPF: best overall. Sharp case edges, correct dial color, clone 324 SC available. $480 to $700.
- 3K: best dial. Deeper sunburst, centered date wheel, softer case edges. $420 to $600.
- PF: value pick. Good case, weaker bracelet with a rattly clasp. $300 to $400.
- SWF: cheapest usable option. Thin dial printing, flat blue color, but the size is right. $220 to $300.
What separates a good 5711 replica from a bad one
Case thickness
The genuine 5711/1A measures 8.3mm. Anything over 9.2mm reads as a different watch on the wrist, and the caseback will not sit flat. Ask the seller for a caliper photo before you pay.
Dial color and print
The blue should shift from navy at the edges to a lighter tone in the center. Flat royal blue is the common tell on cheap builds. Check that the brand print sits centered under the 12 marker and the minute track is crisp.
Bracelet and clasp
The 5711 is an integrated-bracelet watch, so the bracelet is half the design. Run a fingernail along the link edges. Sharp burrs mean a low-tier polish. The clasp should close with a firm click and sit level with the caseback.
Movement choice
A Miyota 9015 is reliable, cheap to service, and beats at 28,800 vph. A clone 324 SC looks closer through the caseback but costs about $150 more and is harder to repair. For daily wear, the Miyota is the safer call.
Option two: 3K Nautilus 5711/1A
Pick the 3K if the dial matters more than the case finishing. Its blue sunburst comes closest to the real thing among the four, and the date window sits where it should.
The trade-off is a softer bezel bevel and a bracelet that feels a touch lighter in the hand.
Option three and four: PF and SWF
PF makes sense if you want the 5711 look for under $400 and plan to swap the bracelet for a leather strap. SWF is the pick for a first replica or a gift, where the price gap beats the detail gap.
How much should a fake Nautilus 5711/1A cost?
Plan on $450 to $700 for a top-tier build with a clone or Swiss movement. Under $300 you lose the dial color and the bracelet finish. Over $800 you are paying for a seller's name, not a better watch.
What to ask the seller before you pay
- A caliper photo of the case thickness, measured at the lugs
- A short video of the clasp opening and closing
- A clear photo of the movement and rotor
- A timestamped photo of the actual watch you will receive
- The return window, in writing, plus who pays shipping back
FAQ
Is the 5711/1A replica waterproof?
Most builds handle hand washing, not swimming. The caseback gasket and crown tube are the weak points. Have a watchmaker pressure test it before you take it near water.
Can a jeweler tell it is a replica?
Yes, under a loupe. The finishing on the movement bridges and the date font give it away. On the wrist at arm's length, a top-tier build passes casual inspection.
Which dial color should I choose?
Blue is the classic and the safest bet. The green 5711/1A-014 dial is harder to copy, so color match on replica green dials is weaker.
Do replica 5711 bracelets fit aftermarket straps?
No. The integrated lugs use a custom end link. You need a strap cut for the 5711 case, or the bracelet stays on.
