Cartier's masterpiece Santos Octagon has been available since the 1980s.
The items that arrived today are ``battery-powered''.
This watch is different from other watches.
A rare item that was sold together with a battery-powered model and an automatic winding model, which was rare at the time.
Easy to tell apart; battery-operated models have ivory-colored dials;
Automatic winding has a white dial.
And the SM size with date is battery operated.
Both LM sizes come with a date,
You can easily tell by the color of the dial once you get used to it.
The size of the case is almost the same.
The automatic winding watch is a little thicker.
The difference is so noticeable that you can just compare it.
It will be almost the same design.
However, for those who don't know much about watches,
I don't think you can tell which is which, so
If you want to have a quick look without having to operate anything, there is a battery-operated option.
I think automatic winding is better for those who want to spend a little time on the operation.
These slightly complicated watches,
It can be said that it is a lineup unique to vintage models,
I think it would be good if you could find that part interesting as well.
