Seiko’s dive watches are among the best — and the most affordable, relative to their specs — in watchmaking.

From the rare-as-hen's-teeth 6159, to the film-famous 6105 and 6309 models, to the economy workhorse SKX007, Japanese watchmakers perfected incredibly well-made tool watches decades ago — and at prices that make the most diehard Swiss watch fans bristle with jealousy.

The particular Seiko diver we have here is an SLA039, a high-end, limited-edition recreation of the Reference 6159-7001 from 1968. A professional-grade instrument meant for offshore divers, the 6159-7001 has become ingrained in Seiko lore as one of the brand’s most capable tool watches.

Housed in a 45mm stainless steel monoblock case with holey lugs, a sapphire crystal, and a black ceramic unidirectional dive bezel, it features a sunburst blue dial with applied luminous plots, a matching ‘sword’ handset, and a date window at 3 o’clock. Water-resistant to 300m, undeniably handsome, and limited to just 1,100 pieces, the SLA039 is powered by Seiko’s Hi-Beat Caliber 8L55 with 37 jewels and 55 hours of power reserve. Further, it comes fitted to a blue rubber ‘studded’ dive strap with a stainless steel hardware, and is accompanied by its factory goodies.

Seiko has a reputation for affordability, and indeed, many of its products are eminently attainable. The SLA039 is not such a watch — it’s a serious wrist companion for the serious diver, and it warrants a closer look.

Have at it!
