The origins of the Duometre.

Did anybody wonder what are the origins of the Duometre?

Cal 381 on the left ( Quantième Lunaire ), and 380 on the right ( Chronographe ) :



I heard that the origins could be found in a pocket watch from the ... 19th Century.

1881, to be exact.

So, when I was at the Manufacture, I asked the Heritage Gallery to kindly show me this watch.

Which they kindly did.

The Cal 1920 RMSMI ( Repetition Minute Seconde Morte Inédpendante )



A closer view on the double gears train, one being dedicated to the Seconde Morte:

While the second is in charge of the other functions: Minute Repeater and Time.

A picture of this superb watch on its document:



On the aesthetical side, now, which JLC watch marked the start of the " Cotes Soleillées "?

The Antoine LeCoultre 8 Days, in 2003, to celebrate Antoine Lecoultre's 200th Birthday ( Cal 877 ).

Here is a picture of the Cal 876, which is basically the same, at the difference of a perpetual calendar module.



So, yes, two dates are important, when it comes to the Duometre movements: 1881, and 2003.

Interesting, isn't it?

Best.

Nicolas.
