Seiko SKX007 Review: The Legendary Dive Watch Discontinued

If you ask any watch enthusiast for the best entry-level mechanical dive watch, the answer for nearly two decades was the same: Seiko SKX007. Discontinued in 2019, this affordable ISO-certified 200m diver became the gateway drug for a generation of collectors.

Why It Became a Legend

The SKX007 nailed an unusual combination at its $200–$300 retail price: ISO 6425 dive certification, automatic movement, screw-down crown, unidirectional bezel, lume on hands and indices. No other watch at this price ticked all those boxes.

Movement: Calibre 7S26

The 7S26 is the workhorse of Japanese horology — 21 jewels, 41-hour power reserve, accuracy of -20/+40 seconds per day. By chronometer standards, that's mediocre. By "I dropped it and it still works" standards, it is unbeatable.

The Cult Following

The SKX007 spawned an entire modding community. Crystal swaps to sapphire, bezel inserts in every imaginable colour, ceramic chapter rings, custom dials — the watch became a canvas. Even straight from Seiko, the design was understated enough to wear casually or with a suit.

The Discontinuation

Seiko killed the SKX line in 2019, replacing it with the more expensive SRPE/SRPD "Seiko 5 Sports" range that lost the 200m rating, screw-down crown, and ISO certification. Enthusiasts were furious. Used SKX007 prices have since risen from $300 to $450–$600.

Should You Buy One Today?

Yes — but only carefully. Buy from a reputable seller, ideally with original box and papers. Check the bezel action, ensure the lume works, and verify the movement isn't losing more than 30 seconds per day.

Verdict

The SKX007 is one of the most important watches of the modern era. It taught countless enthusiasts that mechanical dive watches don't need to cost thousands. Even at $500 used, it remains exceptional value.
