Some pictures of the Jaeger Lecoultre Duometre à Spherotourbillon.
This is one of the watches I had the pleasure to attend its making of.
Still, it is not my favorite Duometre.
The good / remarkable points?
It is a Duometre, with a tourbillon turning on different axes which is always magical, with a cylindric hair spring, which adds to the magic, and a GMT.
Another very important point is that it has a great level of finishings.
Now the less good point, for me, is that all these technology and horological skills let me cold...
For the moment, my favorite Duometre are the Chronograph, the UTT and the Quantième Lunaire Enamel, in this order.
