In watch talk, a hippocampus is the seahorse medallion stamped on the back of an Omega Seamaster. A fake hippocampus is one that was cut, cast, or etched by someone other than Omega. The 2014 in the search is a year, not a model. It shows up because Seamaster references from that stretch get compared often, and because Omega's Seamaster family was shifting under Master Co-Axial movements right around then. There is no Omega release called the Hippocampus.
If you arrived here from a neuroscience search, that is a different hippocampus entirely. Nothing below applies to it.
Why a seahorse sits on a caseback
The word comes from Greek and means roughly "horse monster." It is the animal we call a seahorse. Omega put it on the Seamaster back in 1957 and never really let go of it. On older watches it appears as a stamped medallion, often with stylized waves below the animal and "Seamaster" in script somewhere nearby. On modern solid casebacks it is usually a round medallion centered on the back, cut deep enough that light and shadow define it.

The medallion is small, which is exactly why it gets copied badly. A die that is a fraction off, or a laser that runs too fast, and the seahorse turns into a soft blob with fins missing.
Where 2014 fits in
By 2014 a large share of Seamaster models ran Master Co-Axial movements. The Seamaster 300 introduced that year has a sapphire display back, so there is no seahorse to inspect at all. The Seamaster Diver 300M of the same period kept a solid back with the medallion. That contrast is useful. If a listing calls a watch a 2014 Seamaster 300 and then shows you a stamped seahorse caseback, the two details do not belong on the same watch. Either the year is wrong or the back is.
How I judge a hippocampus stamp
- Depth. A real medallion is struck into steel. You can feel the edge with a fingernail and see a hard shadow line at an angle. Copies tend to look shallow, waxy, or printed on a flat disc.
- The animal itself. Look at the snout, the small dorsal fin, and the curled tail. Copies lose the fin first, then round off the snout until it reads as a comma.
- The waves. Count them and check their shape. Mushy or uneven wave lines under the seahorse are a common tell.
- The ring and script. The border circle should be even all the way around. "Seamaster" script should have clean thick and thin strokes, not a uniform line.
- Caseback text. Check the font and spacing of the brand name, the reference number, and the water resistance rating. Wrong letterforms show up faster than a wrong seahorse.
- Reference logic. A watch sold as a 2014 reference should not carry a reference number from the 1990s, and the movement should match the era.
What this means when you are comparing replicas
On a display-back watch, the medallion is irrelevant because it is not there. On a solid-back Seamaster it becomes the largest single surface on the watch, and it sits flat against your wrist where nobody sees it but you. That is why buyers argue about it online and why sellers photograph it straight on and at a raking angle. Ask for both shots. A straight-on photo hides depth. An angled photo hides symmetry. You need the pair to know what you are looking at.
Weigh the rest of the case too. Caseback engravings are usually done in the same pass as the rest of the finishing, so if the bezel action feels cheap or the crown threads catch, the medallion is rarely the only weak point.
Bottom line
A fake hippocampus is a copied seahorse medallion, nothing more exotic than that. 2014 is a reference year people use when comparing Seamaster casebacks, and it is a good one because the line split between display backs and solid backs around then. Check depth, the fin, the waves, and the text. If one of those is off, the back was not made where the seller says it was.
