The Seastar name first appeared in the Tissot catalogue in 1954, but not as a dive watch, or a chronograph. It was in reference to its caseback, which used new technology to repel moisture and dust. The latest iterations certainly do that. True to its name, the Seastar 1000 offers up a whopping 300m (1000ft) of water resistance, due in part to its screw down crown and caseback. To achieve this in the chronograph version, the brand has also designed funky, screw down pushers.
People marvel at what they cannot understand. And the function of a mechanical watch is indeed a minor marvel. But people cannot marvel at what they cannot see. So what's what better than a watch with an open heart? A watch with a skeletonized dial. In other words, don't just show them them balance wheel. Give 'em the gears.
