Seiko Prospex Solar SNE591P1 is designed and manufactured to withstand up to 200m going under the water, and is suitable for wearing while scuba diving.

The crown has screw-down protection to prevent it from being pulled out by any accidental operation as the water resistance function is secured only when the crown is at its normal position.

Seiko Solar technology converts all types of light into energy to power a watch thanks to a solar cell with high performance electricity generation.

The precise and secure operation of the uni-directional bezel prevent accidental rotation, so that the time measured is never shorter than the actual elapsed time.
