Vintage watch listings have their own dialect. Nobody warns you that "working" and "serviced" are not the same thing, and that "spares or repair" is not a polite way of saying "a bit tired."
Here's the plain-English translation, so you know what you're getting before you click buy.
"Serviced"
What it means: A watchmaker has opened the watch, cleaned the movement, replaced worn parts, re-oiled it, and checked it keeps decent time. Think of it as a full MOT for your wrist.
What it doesn't mean: Brand new, waterproof, or guaranteed forever. A service doesn't fix a scratched crystal or a faded dial, and on older watches, water resistance is never something to test in the shower.
Worth asking: Who did the service, and when? A service from last month is great. "Serviced at some point" is a shrug in a trench coat.
"Working"
What it means: The watch runs. Wind it, set it, and the hands go round.
What it doesn't mean: That it's been serviced, that it keeps perfect time, or that it will keep running for decades without attention. A "working" watch might gain a few minutes a day, or its oil may be old and tired. It's a bit like a car that starts on the first turn of the key but hasn't seen a garage in years.
The good news: Plenty of working watches are lovely, and they're often the best value for buyers who want a characterful watch at a fair price. Just go in knowing a service may be on the horizon.
"Spares or Repair"
What it means: Something is wrong, and the seller isn't promising otherwise. It might be a stopped movement, a missing part, a cracked crystal, or a mystery rattle.
What it doesn't mean: Worthless. These are for hobbyists, tinkerers, and anyone who enjoys a project. A watch that needs a new crown might cost very little to fix. One that needs a rare movement part might be better as a donor for another watch.
Who it's for: People who know what they're doing, or who have a watchmaker they trust. If you're buying your first vintage watch, this probably isn't the grade to start with.
Questions Worth Asking Any Seller
When was it last serviced, and is there paperwork?
How does it keep time over a full day?
Is the crystal, dial, and case original?
Is there any known fault, even a small one?
Can I see photos of the movement?
A good seller will answer all of these without getting twitchy. If they won't, that tells you something too.
The Bottom Line
No grade is "good" or "bad." They're just labels for how much work has been done and how much is left for you. A serviced watch costs more because someone already paid the watchmaker. A working watch is cheaper because you might be the one paying later. A spares-or-repair watch is cheapest because you're buying potential.
