| Where | eBay item 237175743480, seller todaysbrilliancejewelery (99.4%) — ends Tue Nov 17, 2026, 11:46 AM PT |
| The angle | Parts examples ask $250 and running 6117s typically ask $400+; this one is stated running, at $34, with its fault — a scratched crystal — disclosed |
| Verdict | A running early Seiko GMT at a parts-watch spot. The gap is checked, and the crystal is the known cost. |
What it is
The 6117-6400 is Seiko's World Time of 1971: an automatic GMT with a rotating city ring, from the years when Seiko's travel watches were built like instruments rather than jewellery. This example is listed by todaysbrilliancejewelery (99.4%) as Pre-owned — Good. The seller states it "ran for me on a flat surface for 24 hours and keep great time" — their wording, quoted in the caption — and lists it head-only, with no band, and a crystal that has scratches.
Matthew approved this pick on Nov 10. By the pre-post re-check on Wed Nov 11 the auction had already moved to $70.00 on 12 bids; the article keeps the Nov 10 spotted figures, per the series convention — the pick is the spot, not a prediction of the hammer.
Why it matters
The eBay Pick bar is a checked value gap, or no pick. Here the comparison is in the caption record: parts examples of the reference ask $250, and running 6117s typically ask $400 or more, against a $34 spot for a watch the seller states is running and keeping time. What you are buying into is equally plain — a scratched crystal and a bare head that needs a strap before it needs anything else.

What to check before bidding
- The crystal has scratches. Stated by the seller. Price a replacement or a polish into your ceiling.
- It ships head-only. No band — budget a strap, and check the lug width from the listing photos before it arrives.
- "Kept great time" is a 24-hour flat-surface test. The seller's own wording. It is a running watch, not a serviced one; accuracy across positions is untested.
- The spot has already moved. $70 on 12 bids at the Nov 11 re-check, with the auction running to Tue Nov 17, 11:46 AM PT. Decide your ceiling now, not in the last minute.
