Seiko Diver's 200m (SKX) SKX007
Specs, Market Price & Buying Guide
- The Seiko SKX007 is the benchmark affordable ISO 6425 dive watch — produced from 1996 to 2019, powered by the 7S26 automatic, and still the reference against which every sub-$500 diver is judged.
- Market range: roughly $300–$420 on the secondary market (verified Aug 16, 2026 — it is discontinued, so condition drives price).
- Availability: discontinued since 2019. Secondary market only; the Seiko 5 Sports SRPD line is the official successor.

How it wears, by wrist size
Surprisingly good — the 46mm lug-to-lug and 4 o'clock crown are why the SKX fits wrists that '42mm' says it shouldn't.
The sweet spot; this is the wrist size the SKX legend was built on.
Compact and tool-like; the jubilee keeps it casual.
Wears smallish but purposeful; many big-wrist owners never notice.
Buy or skip?
Editorial take: 8/10 — buy it for what it is, not what it was.
The SKX007 earned its reputation the hard way: two decades of actual diving at a price nobody could touch. In 2026 the calculus has changed — at $300–$420 used you are paying collector-era money for a movement (7S26) that does not hack or hand-wind, under a Hardlex crystal, with zero warranty. If you specifically want the SKX — the proportions, the history, the mod scene — buy the best example you can find and enjoy it. If you just want a great affordable diver, the modern alternatives below do more for less.
- You want hacking and hand-winding — the 7S26 has neither.
- You want a warranty — discontinued means secondary market only, as-is.
- You want sapphire — Hardlex shrugs off knocks but collects scratches.

| Watch | Case | Movement | Crystal | Water | Typical price |

Ownership costs
| Cost item | Detail |
|---|---|
| Service | 7S26 service runs $100–$180; many owners simply run them until they stop — movements are cheap to swap. |
| Mods | The SKX is the most-modded watch in history; cases, dials, hands and movements (NH36 upgrades) are an entire industry. |
| Parts | Bezels, inserts and crystals are widely available; check a used example's bezel action before anything else. |
| Resale | Values have climbed since discontinuation; clean, unmodified examples hold best. |
Frequently asked questions
SKX007 vs SKX009 — what is the difference?
Color only. The 007 is black dial and black bezel; the 009 is blue dial with the red-and-blue 'Pepsi' bezel. Same case, same 7S26, same ISO 6425 rating.
Is the SKX007 a real dive watch?
Yes — ISO 6425 compliant and rated to 200m. For two decades it was the default choice of working divers on a budget, which is exactly why it has the reputation it does.
Is the SKX007 worth $350+ in 2026?
Only if you want the SKX itself — the proportions, the history, the mod platform. Purely on specs, the SRPD successor and tribute options like the Islander give you hacking, hand-winding and sapphire for the same money or less.
What should I check when buying a used SKX?
Bezel action and insert fade first, then Hardlex scratches, day-date quickset function, jubilee stretch, and whether the 7S26 holds a healthy amplitude. Budget a service if there is no history.
Where to buy safely
eBay and Chrono24 carry the deepest supply at $300–$420; buy the seller, then the watch.
r/Watchexchange and watch forums often price more fairly; check feedback history carefully.
Japanese-market stock surfaces regularly; confirm import costs and returns before committing.
Expect a steep premium and scrutinize hard — NOS claims on a 2019-discontinued watch are often optimistic.
