Aqu a Ter ra from the hippocampus watch family is closely linked to the ocean, and the vertical ‘teak concept’ texture is reminiscent of the teak deck on a luxury yacht.

In terms of movement, Omega selected a movement equipped with a silicon escapement. Silicon is a non-magnetic substance, which is more precise than the balance spring of traditional materials. The slight vibrations in daily life can cause deviations in the movement of the mechanical watch, but the silicon balance spring makes the impact of the vibration minimal.
