The top pick for most buyers is a Tiffany-blue 5711/1A-018 style build from a top-tier 1:1 workshop, because that is the limited edition people picture when they search for the reference and it has the hardest dial to copy well. The criteria behind that call are simple: case thickness and profile match, dial color accuracy in daylight, movement quality (a clone 324 S C rather than a decorated generic), bracelet taper and link finishing, and whether the seller can supply the same spec twice.
What limited edition means on a real 5711
Patek Philippe built the Nautilus line around scarcity, and three 5711 runs are the ones sellers reference when they use the phrase limited edition. The 5711/1P 40th anniversary from 2016 came in platinum and was capped at 700 pieces. The 5711/1A-018 with the Tiffany & Co. blue dial arrived in 2021 and was capped at 170 pieces. The 5711/1A-014 with the olive green dial was the final steel 5711 before discontinuation, and while it was not a numbered run, it closed out the reference.
On the replica side, limited edition is a style label, not a production cap. No workshop is holding a numbered run of 170 pieces. Treat the wording as a signal about which genuine reference the build is copying, nothing more.
Criterion one: case profile and thickness
The genuine 5711 is a 40 mm case at roughly 8.3 mm thick, and that slimness is what makes the Nautilus silhouette work. A replica that adds a millimeter looks bulky on the wrist and the bezel proportions drift with it.
- Pass: side profile photos next to a ruler, or caliper readings from the seller.
- Pass: the rounded octagonal bezel with a satin-brushed top and polished bevels.
- Fail: a case that looks flat or slab-sided in profile shots.
- Fail: sellers who only show wrist shots from a straight-on angle.
Criterion two: the movement
The 5711 has a sapphire display back, so the movement is visible and worth judging. The genuine 324 S C runs at 28,800 vph with about 45 hours of reserve, a gold rotor and Geneva stripes. Replica options fall into two groups: a clone 324 S C with correct beat rate and rotor engraving, or a Miyota 9015 under a decorative plate.
- Clone 324 S C: correct look through the caseback, closer winding feel, harder to service.
- Miyota based: smoother reliability, easier and cheaper to service, engraving that a trained eye can spot.
Ask for a photo with the caseback open and a short video with the rotor turning.
Criterion three: dial color and printing
Tiffany blue is a specific turquoise, and most replica dials land too green or too saturated. The olive green 5711/1A-014 has the same problem in reverse, often reading flat and gray in low light. The platinum 5711/1P adds the 40 and 1976-2016 text at six o'clock, which is a small printing job that many builds get wrong.
Judge dials from a daylight video, not from studio photos with colored lighting. Check that the hour markers sit level, that the date window edges are crisp, and that the applied logo has depth rather than a flat print.
Criterion four: bracelet and clasp
The integrated Nautilus bracelet tapers from the case to the clasp and mixes brushed link faces with polished bevels. A good build carries that taper through every link and closes with an engraved fold-over clasp that sits flat on the wrist. A weak build has loose links, uneven brushing and a clasp that rattles.
The three builds worth considering
Tiffany-blue 5711/1A-018 style
Pros
- Strongest visual match to a documented limited edition.
- Tiffany blue is easy to recognize and easy to show off.
- Widely produced, so replacement parts and dials exist.
Cons
- Hardest dial color to match, so quality varies more than any other version.
- Highest scrutiny from anyone who knows the reference.
Best for the buyer who wants the recognisable limited edition look and will accept that the dial is the make-or-break detail.
Platinum-look 5711/1P 40th anniversary style
Pros
- Rare enough that few people have seen the real one next to it.
- The 40 and 1976-2016 printing adds detail that reads as special.
- Platinum-tone finishing hides small case flaws better than polished steel.
Cons
- No genuine platinum weight, so the heft is lighter than the reference implies.
- The anniversary text is often slightly off in size and position.
Best for a collector who prefers a quieter, less obvious version.
Olive-green 5711/1A-014 style
Pros
- Steel case and bracelet, so the weight and feel are easier to get right.
- The green dial hides small finishing issues in low light.
- Reads as the final reference, which carries its own appeal.
Cons
- Green is a narrow taste and harder to wear with everything.
- Dial finish ranges from satin to flat depending on the batch.
Best for a daily wearer who wants the Nautilus shape without the Tiffany blue attention.
How to vet a limited edition listing
- Ask for an unedited daylight video of the watch on a wrist and on a table.
- Request caliper or ruler shots that show the case thickness from the side.
- Ask which movement is inside and for a caseback photo.
- Ask for close-ups of the clasp, end links and date window.
- Confirm the return window and whether the same spec can be repeated on a second order.
What to avoid
- Listings that say limited edition without naming a reference number.
- Photos taken under colored or heavy studio lighting.
- Prices far below the going rate for the tier, which usually means a bait-and-switch on the shipped piece.
- Sellers who cannot show an open caseback or a live video.
Legal and ownership notes for US buyers
Counterfeit watches are subject to seizure by U.S. Customs and Border Protection, and importing them carries risk of loss with no refund from the carrier. Reselling a replica is trademark infringement and a separate, more serious problem than owning one. On the ownership side, treat water resistance as unverified, keep the watch away from pools and showers, and expect that a clone movement will need a service long before a Japanese one does.
