Cartier Santos Dumont Ultra-thin Guilloché Dial ref. 82105 in 18k Yellow Gold Box and Paper Set

By now, most are familiar with the iconic story of Louis Cartier designing a wristwatch for his friend, aviation pioneer Alberto Santos-Dumont. That historic creation would go on to become one of the most enduring classics in watchmaking — a true icon in the world of horology.

 

Over time, the ultra-thin variants — or extra plate, as the French elegantly put it — have earned a special place in collectors' hearts. And with good reason: they’re not just ultra-thin, they’re also undeniably cool.

 

Let us elaborate:

 

These hand-wound versions are noticeably slimmer than automatic references like the 2960. The result is a refined profile that hugs the wrist beautifully, offering both comfort and understated elegance. In our view, these are among the most desirable Santos models to own.

 

This particular example features an 18k yellow gold case in excellent condition, with a crisp bezel that retains its sharp lines. The rare silver guilloché dial, hand-finished with Cartier’s signature black Roman numerals, includes a discreet “Cartier” inscription hidden at 7 o'clock — a hallmark of authenticity. It comes paired with the leather strap shown, and is fitted with an original 18k yellow gold Cartier pin buckle. 

 

Powering the watch is the ultra-thin, hand-wound movement based on the celebrated Frédérique Piguet Cal. 21, which has been fully serviced by our watchmaker. This cool Santos' comes with its original Cartier box and the certificate states a sale in 1995, Kuwait.
