规格
Circle, triangle, square. Shapes that spell safety to the diver.
When you’re diving, legibility is everything. When the water is murky and when clear thinking can be clouded by the conditions, you need a watch that is as reliable and legible as can be. This is why the 12 o’clock marker is a triangle, the 6 a rectangle and the others circles. It’s also why the hour and minute hands are very different shapes and lengths and generously coated in Lumibrite. The exact time is easy to read, even at a glance, deep below the surface. SBGA461 puts safety first, where it belongs.
