Barometer

Measuring atmospheric pressure, a barometer is built in to some models in the SEA range, and is used to forecast changes in weather conditions.

Depth Gauge

For those who venture beneath the waves, the depth gauge which features in certain SEA watches is a vital instrument. Enabling the wearer to precisely track their progress underwater, and ensure that they are safely positioned, this is essential kit for any diver.
