"Hippocampus" is the Latin word for seahorse. Omega stamps a seahorse on the caseback of every Seamaster. In search data, "replica hippocampus 2020" stands for replica Omega Seamaster watches traded in 2020. Omega does not use "Hippocampus" as a model name. Listings vary, and some sellers apply the term to any Seamaster that carries the seahorse emblem.
Short answer: the 2020 copies came in three grades. Low grade cost $60 to $120. Mid grade cost $150 to $300. High grade "super clone" cost $350 to $600. None matched the movement, the magnetic resistance, or the METAS certification of the genuine watch.

What Is Unverified
