Dive watches are often touted as the most versatile style of watch. They tend to strike the perfect balance between ruggedness and wearability. They’re perfect for everyday use, tool watch duties, and formalwear. For most watch collectors, myself included, a dive watch is always present in their collection.
In the affordable watch market (<$1k), Seiko’s SKX line has been king for the last few decades. It was tough (I’d argue “impossible) to beat the value of an SKX. For decades, $200 (or less if going preowned”) could get you an ISO certified diver with torch-like lume. Often times, what was lacking, like applied indices and some quality control issues, was compensated by the strong brand name and respect Seiko carries. If you ever needed an affordable diver, the SKX line was the way to go; a million recommendations online can back that statement.
