Cartier Panthere WSPN0012: specifications and what to check

Cartier specifies the case and bracelet as one thing

The materials line reads steel case and bracelet — a single entry, not two.

That is the right way to think about this reference when you are buying one. The Panthère's articulated link bracelet is not a band attached to a watch; it is most of the object, most of the surface area, and most of what can be wrong.

So invert the usual inspection order and start with the bracelet.

Stretch. Support one end and let the rest hang level, then judge the sag. Small links mean a great many pin joints, and every joint is somewhere for wear to gather. A stretched Panthère bracelet is obvious on the wrist and expensive to put right.

Splay. Under a loupe, look along the edges for links that have opened slightly at the pins. At this scale, wear that would be invisible on a 22 mm sports bracelet reads as a visible kink in the line.

Repairs. Look for a link that is brighter, duller or fractionally different in finish from its neighbours. Replacement links exist and do not always match.

Links removed. Ask where they are. A mini Panthère sized for a small wrist cannot be made longer again without the originals, and that limits who you can sell it to.

Six millimetres, twenty-five by nineteen

Published: 25 mm x 19 mm, 6 mm thick.

Six millimetres is thinner than anything else on this site — the slimmest round case here, a Tissot at 9 mm, is half again as deep — and the proportions are unlike anything else in the corpus. There is no diameter — the case is rectangular — so quote both dimensions, and quote the thickness, because it is the number that explains how the watch disappears under a cuff.

Nobody buying this reference is surprised that it is small. Plenty are surprised by how small if they have only seen it photographed on its own.

Quartz, and nothing else stated

Cartier's movement specification is two words: Quartz movement.

No calibre. No battery life. No accuracy figure.

Confirm the movement behaves as quartz on the watch in front of you, describe it as Cartier does, and if a buyer asks how long the battery lasts, say that Cartier does not publish a figure. That is a better answer than a number you cannot stand behind.

The crown, the crystal, the rating

The crown is octagonal, set with a blue synthetic spinel — distinct from the beaded and faceted crowns on the Tank references here, and from the seven-sided Santos crown. At this size it is small and fiddly; check that it still pulls and pushes cleanly, and that the stone is chip-free and firmly seated.

The crystal is sapphire, which Cartier does state for this reference — worth noting, because it declines to state a crystal material on the Tank Must.

The dial is silver with blued-steel sword-shaped hands; give the hands a loupe, since blued steel records handling permanently.

The rating, as Cartier gives it, is 3 bar (approx. 30 meters/100 feet) — which covers a downpour and a basin, and stops there. Spell that out in the listing.
