Short Answer
A Hippocampus 212.10.44.51.01.001 replica copies the Omega Seamaster Diver 300M chronograph: a 44 mm stainless steel dive watch with a black wave dial, a ceramic bezel insert, a helium escape valve at 10 o'clock, and a three-register chronograph. Hippocampus is the Greek word for seahorse, the emblem Omega has stamped on Seamaster casebacks since 1957, and buyers in several markets use it as the model name. If a listing carries this reference but shows a 41 mm three-hand diver or a two-register dial, the photos and the number do not match.

How To Read The Reference Number
Omega builds reference strings in blocks, so you can test a seller's claims against the number itself.
- 212 points to the Seamaster chronograph family.
- 44 is the case diameter in millimeters.
- 51 covers the movement group.
- 01.001 covers dial color and case finish.
Confirm the last two blocks on the manufacturer page before you pay. Replica makers reuse popular references on cases with the wrong size, and the number is the fastest way to catch it.
The Ultimate Guide to the Hippocampus 212.10.44.51.01.001 Fake Watch
Prerequisites
- Calipers or a digital rule that reads to 0.1 mm.
- A kitchen scale that reads to 1 gram.
- A bright lamp and a UV torch for lume checks.
- Macro photos of the actual watch, not catalog renders.
- A jeweler willing to pressure test a watch they did not sell.
Inspection Steps
- Measure the case across the widest point, excluding the crown. A correct 44 mm case reads 43.8 mm to 44.2 mm.
- Measure thickness from caseback to crystal top. Anything under 15 mm is too thin for this model, and the subdials will sit shallow.
- Rotate the watch under a lamp and check that the dial print is centered inside the rehaut, with no dust under the crystal.
- Rest one drop of water on the crystal. Sapphire holds it in a tight bead; mineral glass lets it spread.
- Turn the bezel through a full rotation. It should click at 120 positions with no back play, and the triangle at 12 should line up with the dial marker.
- Pull the crown to the date position and watch the flip. A clean movement changes the date within ten minutes either side of midnight.
- Run the chronograph through three full cycles. Start, stop, reset, then confirm every hand lands on zero.
- Charge the dial under a lamp for 30 seconds, then step into a dark room. The pip, hour markers, and hands should all glow.
- Flip the watch and read the caseback engraving with a loupe. Letters should be crisp and level, not fuzzy or double struck.
- Weigh the watch head. A steel 44 mm chronograph on a full bracelet usually lands between 180 g and 210 g.
- Ask the jeweler to pressure test the case and stop at 50 m.
- Photograph every fault in macro before you accept delivery or open a dispute.
Movement Tiers
Replicas of this reference ship with one of three movements. A quartz chronograph is the cheapest and the easiest to spot, because the seconds hand ticks once per second. A Chinese automatic chronograph built on the Valjoux 7750 architecture gives a sweeping seconds hand and a working three-register layout, but it runs thick and loud. The top tier uses a decorated automatic chronograph with a column wheel or a modular chrono plate, and it is the only tier worth buying for daily wear. Ask for a photo of the movement. If the listing has none, assume the lowest tier.

Finishing Details That Give A Replica Away
Look at the hands first. Genuine Seamaster hands are skeletonized with polished edges, and cheap replicas leave them flat and painted. Then check the bezel insert. Ceramic reflects light in a hard line; printed aluminum looks chalky. Next, inspect the end links where the bracelet meets the case. Poor replicas leave a visible gap and a sharp edge that catches on a shirt cuff. Last, compare the font on the clasp to the font on the dial. Makers often get one right and the other wrong.
Water Resistance And Legal Reality
Do not dive with a replica of this reference. Gaskets, caseback threads, and crystal seating on replica cases rarely hold pressure, and a flood ruins the movement in minutes. Wear it for desk duty and rinse it under a tap at most. Note also that importing a counterfeit watch can lead to seizure and destruction at customs in the United States and the European Union, and that selling one as genuine is trademark infringement. Price that risk into the decision.
