The case for it

Six-hundred-metre water resistance, ceramic components and a compact span make it a technically serious alternative to the Diver 300M.

What goes wrong

Thickness, bracelet weight, helium valve, retail discounting and service evidence matter more than the compact diameter headline.

Who it fits

Best for someone who wants real dive-watch substance on a moderate wrist and does not need a slim profile.
