What Makes a 3800/1A Super Clone Worth Buying?
A Patek Philippe 3800/1A super clone is worth buying when the case measures 37.5mm across, an automatic movement sits inside (Miyota 9015, Seagull ST2130, or a decorated ETA 2892 clone), and the bracelet integrates into the case instead of attaching with spring bars. Those three details separate a wearable copy from a quartz watch in a Nautilus-shaped shell. Dial color, engraving depth, and box paperwork matter, but they matter less.

The 3800/1A is the mid-size Nautilus that Patek Philippe produced from the early 1980s into the 2000s. It resembles the famous 3700/1A and the later 5711, just smaller. That smaller size is exactly what most replica listings get wrong.
Real vs Fake Patek Philippe 3800/1A: How to Tell Them Apart
Which Size Is Correct for a 3800/1A?
37.5mm. Not 40mm, not 42mm. Plenty of sellers take a 5711 copy, photograph it next to a ruler-free wrist, and label it a 3800/1A to catch search traffic.

- Correct: 37.5mm case width, roughly 8.3mm thick, 20mm at the bracelet root.
- Wrong: 40mm or larger cases sold as "3800/1A." These are 5711 or 5726 copies.
- Also wrong: 33mm or 35mm lady's Nautilus cases relabeled as 3800.
Measure your wrist before you order. A 37.5mm integrated-bracelet watch wears larger than its number suggests because the bracelet flows straight out of the case. On a 6.5-inch wrist it reads as a full-size watch. On an 8-inch wrist it reads as a dress piece.

What Movement Should Be Inside?
The genuine 3800/1A uses Patek Philippe caliber 330 SC, an automatic based on the ETA 2892 architecture with a date at 3 o'clock. No replica ships with a real 330 SC, so judge the substitute on accuracy and serviceability.
- Miyota 9015: 28,800 vph, about 42 hours of reserve, thin, easy to service. The best budget pick.
- Seagull ST2130: 28,800 vph, about 40 hours, accurate when regulated. Common in mid-tier builds.
- Decorated 2824 clone: fine if the rotor and bridges carry real Geneva stripes, not printed decals.
- Quartz: skip it. The seconds hand ticks, the case is thicker than 8.3mm, and the date flips in a snap instead of a roll.
Real Specs of the Reference 3800/1A
Compare any listing against this list. If a seller's description drifts from these numbers, the watch is not what the title claims.
- Stainless steel case and integrated steel bracelet, 37.5mm wide.
- Solid case back (no display window) on the original reference.
- Blue or black dial with horizontal embossed texture, date window at 3.
- Sapphire crystal, anti-reflective on the inside.
- Fold-over clasp with the Calatrava cross stamped on the blade.
- Baton hands with luminous fill; no lume on the applied markers in most variants.
What to Ask the Seller Before You Pay
Ask these questions in writing. A seller who dodges any of them is telling you something useful.
- What is the exact case diameter in millimeters, measured at 10 and 4 o'clock?
- Which movement sits inside, and what is its beat rate?
- Is the bracelet integrated, and how many removable links ship with it?
- Is the crystal sapphire or mineral glass?
- Can you send a macro photo of the dial text and the date wheel font?
- What is the return window, and who pays return shipping?
Common Pitfalls When Buying
Most bad purchases trace back to a handful of repeat problems. Watch for these before money changes hands.
- Stock photos from another factory. Ask for a timestamped photo of the actual watch.
- Wrong date font. The 3800 date wheel uses a thin, plain numeral. Fat or serif numerals mark a cheap build.
- Bracelet mismatch. A 3800 bracelet tapers and has a specific link count. A grafted 5711 bracelet sits loose at the lugs.
- Weight off by 20 grams or more. Hollow links and plated brass cases feel light in the hand.
- "Swiss made" claims on a 37.5mm quartz. Quartz Nautilus copies come from a different supply chain.
- No service history on a used copy. A 5-year-old automatic needs a clean and oil, which adds cost.
Price Bands for a 3800/1A Super Clone
Price tracks movement quality and case finishing far more than dial color. These bands reflect typical asking prices from replica dealers.
- $150 to $250: entry tier, often quartz or a low-grade automatic, plated bracelet.
- $300 to $450: Miyota 9015 or ST2130, solid steel case, decent dial texture. The value zone.
- $500 to $850: top tier, hand-finished case edges, better bracelet articulation, sapphire with internal AR.
Anything above $850 for a 3800/1A copy means you are paying for a box, a card, or a story. The watch itself does not get better past that point.
Frequently Asked Questions
Can I swim with a 3800/1A super clone?
Only if the seller states a tested water resistance rating and the case back gasket is new. Most replicas ship with gaskets that are dry or missing. Assume no water resistance unless a pressure test proves otherwise.
Does the 3800/1A super clone come in rose gold?
Yes, but the gold versions are plated, not solid. Plating wears through at the clasp and case edges within a year of daily wear. Steel is the safer buy.
How do I spot a quartz 3800 copy?
Check the running seconds. A smooth sweep at 8 beats per second means mechanical. A tick once per second means quartz. Then measure thickness: quartz cases run thicker than 8.3mm because the battery needs room.
What wrist size suits a 37.5mm Nautilus?
It fits wrists from about 6.25 inches to 7.5 inches with the standard link set. Smaller wrists need links removed; larger wrists need extra links, which few dealers stock.
Final Walkthrough Before Checkout
Confirm the case measures 37.5mm, the movement is automatic at 28,800 vph, and the bracelet is integrated. Ask for real photos, not catalog renders. Pay with a method that allows a chargeback if the watch arrives at 40mm or ticks like a quartz.
If a listing hits all three checks and lands in the $300 to $450 band, you have found the sweet spot for a 3800/1A super clone.
