What the differences cost you
Each note below follows from the published figures in the tables above — what they mean for intake, for a listing, and for the handover. Nothing here estimates a price or a margin.
Where a shared listing template goes wrong
These two differ on case, thickness, dial, crown and bracelet. None of it changes how either watch is handled, but all of it changes what the listing has to say. Copy from one to the other and those are the fields that end up describing the wrong watch.
What to check on each
WSPN0012
- Assess the bracelet before the case. Cartier specifies the case and bracelet together on this reference, the links are small and numerous, and a stretched or repaired bracelet is most of the watch.
- Count the links and ask where any removed ones are. A Panthere sized down for a small wrist cannot be lengthened again without the original links.
- Check each link for splay at the pins under a loupe, since at this scale wear that would be invisible on a sports bracelet shows as a visible kink.
WSTA0129
- Give both case dimensions in the listing. At 25.7 by 21.2 millimetres a single figure will mislead every buyer who reads it, and there is no diameter to quote in any case.
- Watch the seconds display to confirm the movement is quartz as specified, since the Tank Francaise is also made in mechanical versions.
- Check the integrated steel bracelet where it meets the case for stretch and for play at the join, because on a case this small any gap is immediately visible.
