It appears you are right, it is indeed the 403. The 101 and 104 were also used for the Duoplan and are similar in some respects, but different calibres all together as you point out.

BTW, any info on the number of employees in that manufacturing plant?

Very thorough report that many will enjoy to read over and over.
Great work SJX!

the more I am finding it impossible to resist the temptation.
I had a chance to visit the NYC flagship boutique - wow! Now that is the classic definition of luxury Salon!
I agree with you about the dial and casework, Cartier has always been tops in these areas and now that movements are back a top priority, their horological "quality" and interest is second to none.
Kudos, SJX, great intro series and bravo, Cartier!
