Seiko SKX007
The SKX007 is the automatic diver everyone starts with: ISO-rated, 7S26 movement, made from 1996 until Seiko discontinued it in 2019, which is when the price started climbing. It is also the most modded and most faked cheap watch on earth, so the checklist is about originality: a stock SKX is worth more than a modded one, and a Frankenwatch is worth its parts.
This week in Salt Lake City · from the desk, not a writer
The ceiling is for exactly this: Seiko SKX007, as listed. Priced the way the app prices a target you add yourself: from eBay comps (43) on Sep 19; sells-for is 90% of the eBay median, the ceiling leaves 25–30% after you sell.
Is it the right one?
- Reference on the caseback: SKX007K (Malaysia) or SKX007J ("Made in Japan" on the dial, worth a little more). Serial on the caseback gives the month and year (first digit year, second month).
- Dial code at six o'clock: 7S26-0020. Black dial, lume plots with a lollipop seconds hand, 120-click unidirectional bezel, day-date at three, crown at four.
- Stock bracelet (Jubilee) or the rubber Z22 strap; aftermarket straps are fine, aftermarket bezels, dials and hands make it a mod.
Before you drive
- Ask for the reference and serial from the caseback, and whether box and papers are included. Look the reference up; the dial text, hands and caseback engraving must match the maker's photo exactly.
- In person under the loupe: the printing on the dial (fakes are fuzzy), the date wheel font, the caseback engraving depth, the crown logo, the clasp stamping.
- Set the time and date; wind it; time it against your phone for ten minutes; run the chronograph if it has one. Listen to an automatic: it should be near silent.
- Pay after the reference, serial, dial and movement behavior all agree with the reference.
Bring
- A loupe or your phone camera at 3× for the caseback and dial
- A reference photo of the model from the maker's site
- Cash
What to check in person
- Caseback reference and serial vs dial code: all three must agree; a mismatch is a Frankenwatch.
- Under the loupe: dial printing crisp, lume plots even and the same color, the Seiko logo on the crown, the caseback engraving deep and clean.
- Movement: wind by shaking (7S26 does not hand-wind), watch the seconds hand sweep (six beats a second, no stutter), set the day and date and check they jump at midnight when you advance the time.
- Bezel: 120 clicks, no back-play, the lume pip present; crown screws down; crystal (Hardlex) chips at the edge are common and cheap to replace.
- Case: unpolished lug edges are worth more; heavy polishing rounds them off.
- Water resistance is unknown on a used watch; price it as "not tested" and say so when you sell.
The desk's own checklist for this unit
- Reference and serial on the caseback match the model; fakes of Seiko, Tissot, Omega and Rolex are everywhere at every price.
- Runs and keeps time over ten minutes against your phone; date changes; chronograph resets to zero.
- Crown screws down and winds smoothly; crystal free of chips; lugs unpolished (rounded lugs mean heavy refinishing).
- Box, papers and warranty card add real value and prove provenance; ask for them before you drive.
- Ceiling comes from current eBay asks, not sold prices. Treat it as a starting point and tighten it with your own sales.
What goes wrong
- Fakes at every price
- From $30 Seiko clones to $500 "Omegas". The dial printing, the caseback and the movement sound give them away; a jeweler will open the caseback for $20 if the price is high enough to matter.
- Frankenwatch
- Real case, replaced dial and movement. Common on Seiko divers (SKX especially). The serial and the dial code (on the dial at six) must agree with the reference.
- Polished lugs sold as unpolished
- Rounded lug edges mean heavy refinishing; collectors pay less. Compare to the reference photo.
- "Box and papers" that are not that watch's
- The warranty card carries the serial. If it does not match, it is a box.
The message
What the app writes for you, one tap, never above the ceiling. If the ask is under $300 you meet the ask; if it's over, you offer the ceiling.
Hi! Is the SKX still available? I can pick up today with cash near Salt Lake City. Would you take $300?
Then, before you drive: "Could you send a quick video of it powering on and working? Then I'll head straight over with cash."
Where it sells
- eBay with authentication (eBay authenticates watches over $2,000 for free) and Chrono24 are the national markets; local cash sells the under-$500 pieces fastest.
- Photograph the dial straight on in daylight, the caseback, the clasp, the crown, the box and papers, and a short clip of the seconds hand sweeping.
- A fresh strap and a wipe-down are $15 and worth $50; never polish it yourself.
Photograph the caseback, the dial code and a clip of the sweep; title with the reference and the year: "Seiko SKX007K · 2016 · stock · Jubilee bracelet".
Why this one
Discontinued, collected, and under-priced by people who bought it as a beater. A stock example bought from someone who "just wants it gone" is a reliable small flip with a global market.
