What to Look For

200-meter water resistance is the minimum for actual diving.

Unidirectional bezels prevent accidental over-timing of dives. Sapphire crystals resist scratches better than mineral glass. Screw-down crowns improve water resistance. Lume on the dial and hands must be bright enough to read at depth.
