A replica Patek Philippe ref 5711 is a copy of the Nautilus 5711/1A, the 40 mm stainless steel sports watch with an integrated bracelet that Patek Philippe discontinued in 2021. The best versions reproduce the case profile, the brushed and polished surfaces, and the bracelet taper toward the clasp. The weakest ones miss the thickness, the date font and the crown position, which are the three details most people notice first.
Ref 5711 basics before you buy
The original Nautilus 5711/1A measures 40 mm across the case and roughly 8.3 mm thick. It has a rounded octagon bezel, a porthole style case with lateral hinge ears, an integrated bracelet with a locking clasp, and a blue gradient dial on the steel reference. Patek Philippe retired the model in 2021 and moved the design into a larger white gold reference, so the 5711 remains one of the most copied watches on the market.
- Case size: 40 mm, lug to lug around 44 mm
- Profile: slim, dress-watch height on a sports case
- Bracelet: integrated, tapering links, no standard spring bars
- Dial: horizontal grooved texture with a blue gradient finish
- Movement: automatic, centre seconds, date at 3 o'clock
Why the 5711 shape is hard to copy
Most replica watches live or die on one thing: silhouette. The 5711 is a case study in thinness, because the movement has to sit inside a case that is only a few millimetres deep. When a factory uses an off-the-shelf Japanese automatic, the case often grows by a millimetre or more, and that extra height changes how the watch sits on the wrist.
The second hard part is the bracelet. Nautilus links are wide at the case and narrow at the clasp, with alternating brushed and polished faces and a hinge that folds flat. A bracelet that tapers wrongly makes the whole watch look off, even from across a table.
Replica quality tiers explained
Sellers usually group replica Patek Philippe ref 5711 stock into three bands. The names vary, but the differences do not.
- Entry level: mineral glass, thick case, painted dial, basic or quartz movement. Fine for a novelty, poor as a wearable.
- Mid tier: 316L steel, sapphire crystal, reliable Japanese automatic, decent dial texture. Case height is often noticeably thicker than the original.
- High end: 904L steel in some batches, closer case height, decorated clone movement, correct date wheel font, sharper bevels on the bezel and bracelet.
Movement options you will see
The movement decides thickness, reliability and how the seconds hand sweeps.
- Miyota 9015: slim, 28,800 vibrations per hour, easy to service, often fitted with a decorative rotor plate.
- Seiko NH35: common in budget builds, robust but thicker, which pushes the case height up.
- Clone calibre: a copy of the original architecture, sometimes with engraved bridges and a gold-toned rotor. Closer in look, harder to repair, and parts are not always available.
Ask for a timegrapher photo if you buy online. A reading of plus or minus ten seconds per day is normal for a well-regulated clone.
Details to inspect on the watch
Check these points in seller photos or in hand before you commit.
- Date window position and font: the numerals should be thin and centred, not thick or offset.
- Dial texture: fine horizontal grooves that catch light, not a flat print.
- Bezel bevels: polished edges on a brushed top face, with even width all the way round.
- Crown: correct size, sits flush against the case, no gap.
- Bracelet screws: even spacing, screws that sit flush, no burrs.
- Caseback: crisp engraving, correct reference markings, no blurred text.
Fit, wear and everyday use
With a 44 mm lug to lug span, the 5711 style case suits wrists from about 16 cm upward. Because the bracelet is integrated, sizing is done by removing links rather than moving spring bars, so ask for spare links with the watch. Water resistance on any replica should be treated as splash only. Gaskets are not tested to factory standards, so keep it out of pools and showers.
Care and service
Wipe the case with a soft cloth after wear to clear skin oils from the brushed surfaces. Avoid perfume and chlorine, which dull the finish and dry out seals. A Japanese automatic will run for years with a service every five to seven years; a clone movement is better serviced sooner if it starts losing time. Store the watch on a soft pad rather than face down on a hard surface.
Judging a seller
- Real photos of the actual watch, not catalogue images
- Movement photos with the caseback removed or a display back shot
- Clear returns policy and stated shipping times
- Consistent stock across sizes and dial colours
Compare several listings for the same replica Patek Philippe ref 5711 and look for matching specifications. When three sellers quote the same case height and movement, the specification is likely accurate rather than invented.
