Offered here a very nice and rare Cartier Santos Dumont in ladies size.
The case measures 20 mm across by 28.9 mm long. (0.8 inch across by 1.1 inch long)
The case is very well made and is quite heavy.
As pictured here with strap and an 18K yellow gold deployant buckle it weighs 33.5 grams.
It is made out of a solid piece of gold with machined out space for the movement and case back.
Case back is held in place by four 18K gold screws.
White dial with black Roman numerals appears to had been refinished and looks very good.
The hour hand has some of the black paint coating missing and showing gold.
The case is in very good condition as is the crystal and the original crown set with the faceted blue stone.
The watch was serviced in January 2017 and is running fine.
The original Cartier black lizard band is new.
It is attached to the case with a gold screw on each side.
The 18K solid gold deployant buckle is also original Cartier.
The watch with current strap will fit up to 6 and 3/4 inch wrist.
Newer Cartier bands may not fit the deployant without some modification.
For this reason we have made a special gold attachment which fits on one side of the band and allows adjustment of the length of the band. 
The largest setting is for a 6 and 3/4 inch wrist size.
This is the size currently.
To achieve shorter setting some of the leather will need to be cut off and the gold end piece reattached.
We can adjust the length for you prior to shipping or you can have your jeweler measure your wrist and adjust the length of the leather for you.
