Stated for one, not the other
These rows cannot be compared, because one maker publishes the figure and the other does not. An empty cell is a gap in the manufacturer's documentation, not a gap in the watch — and not a licence to fill it in from the other column.
| Clasp | Ardillon buckle in rose gold 750/1000 | not stated |
|---|---|---|
| Calibre | Caliber 1917 MC | not stated |
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.
Two different ownership conversations
The WGTA0011 is hand-wound and the WSTA0129 is quartz. That changes what a buyer needs telling at handover, and it changes intake: a hand-wound watch has no rotor to mask a tired mainspring, and a stopped quartz watch is usually a battery rather than a fault.
One of these is a different asset to hold
The WGTA0011 has a gold case and the WSTA0129 is steel. That is not just a price difference: a precious-metal case changes what your insurer needs told, how the piece should be stored and handled, and — in some jurisdictions — whether trading it puts you under a precious-metals rule your steel stock would not. Check your own city guide before you assume they are the same transaction.
One needs sizing, the other needs stock
The WSTA0129 comes on a bracelet and the WGTA0011 on a strap. They are different jobs at resale: a bracelet has to be sized and its removed links kept with the watch, because a buyer who receives it short of links has received an incomplete watch. A strap is a consumable — check whether the one on the wrist is the one that should be in the photographs.
What to check on each
WGTA0011
- Grade the crystal as mineral, not sapphire. Cartier specifies mineral glass here, which scratches in ordinary use and can often be polished, and describing it as sapphire is a claim the maker does not make.
- Note that Cartier's own page title says Large model while its specification says Medium. Quote the specification and say the title disagrees, rather than picking whichever suits the sale.
- Wind it from stopped and treat the stop as absolute, since the 1917 MC is hand-wound with nothing protecting the mainspring.
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.
