"Hippocampus" is the genus name of the seahorse. Chinese collectors call the Omega Seamaster 海马, which translates to seahorse. Buyers who render that term in English arrive at "hippocampus." Search data links the phrase "hippocampus 2024 imitation" to one product: a replica of the 2024 Omega Seamaster.
The rest of this guide covers which references get copied, what separates a close copy from a poor one, price bands, and legal exposure in the U.S.
Which 2024 Seamaster references see copies
- Seamaster Diver 300M, 42 mm, ref. 210.30.42.20.03.001 and sibling colorways. Steel case, ceramic wave dial, ceramic bezel, helium escape valve at 10 o'clock, date at 6 o'clock.
- Seamaster Diver 300M Bronze Gold, a limited edition tied to the Paris 2024 Olympic Games. Bronze Gold is an Omega alloy with gold content, not standard bronze.
- Seamaster Planet Ocean 600M, 39.5 mm and 43.5 mm.
- Seamaster Aqua Terra 150M, 38 mm and 41 mm.
Genuine specs a copy has to match
The Diver 300M uses Co-Axial Master Chronometer Calibre 8800, a 55-hour power reserve, 300 m water resistance, sapphire crystal, and a ceramic dial with laser-engraved waves. METAS certifies the movement to 0/+5 seconds per day and resistance to 15,000 gauss. Any listing that claims Master Chronometer status for a replica is false: the copy cannot pass the test.
Tells on a replica
- Date wheel. Genuine date sits at 6 o'clock with a matched font. Overlay wheels on clone movements sit off-center and jam.
- Helium escape valve. Genuine unscrews and seals. Many copies fix the crown in place.
- Wave dial. Laser-cut ceramic shows depth under raking light. Copies show shallow waves or a printed pattern.
- Bezel. Genuine ceramic insert with enamel scale, 120 clicks, no back play.
- Movement. Decorated ETA 2824 clones or Miyota 9015 units under a fake bridge. The genuine 8800 has a silicon balance spring and a Co-Axial escapement.
- Lume. Super-LumiNova on indices and hands. Copies dim within a year.
- Caseback. Engravings, NAIAD lock, serial, and reference number.
Checks before payment
- Ask for photos of the actual watch with a dated card. Reject catalog renders.
- Request macro shots of the dial, date window, and caseback.
- Request a timing-machine printout with rate and amplitude.
- Confirm water resistance testing, or accept that none was done.
- Get return terms in writing.
- Pay with a method that allows a dispute.

Legal and practical risk
Counterfeit watches infringe trademarks under the Lanham Act and fall under 18 U.S.C. § 2320. U.S. Customs and Border Protection can seize and destroy shipments. Buyers get no Omega warranty, no service from Omega, and no resale path. Water resistance claims from sellers are unverified unless a test report is attached.
