I wish to finish my report with the watch we already know very well: the Grand Tourbillon Heures Mystérieuses. We may know it but it is always special to see it...
First of all, the original shape of the dial attracts our eyes: it looks like an egg or a drop... but this shape is not a pure aesthetical effect, it is also due to the layout of the dial.
The dial has two objectives: to enhance the mysterious side of the time display (at the bottom) and to propose the best view of the Tourbillon: this Tourbillon is wide-open which gives us the ability to enjoy the sensual curves (yes, I use these words!) of the bridges.
The watch is big (47mm), quite thick (14,4mm) and heavy.
The handwind caliber has a power reserve of 50 hours, smaller than the "equivalent" chronograph caliber (16.29) which has the same diameter, frequency and balance wheel size. It is due to the energy required by the Tourbillon.
Hopefully, Montblanc and Minerva kept the simplicity of the watch: no complication was added in order to be concentrated into the two key functions of the watch: the Tourbillon and the time display. They managed to make a complex watch simple.
Sadly, the caseback is plain but the caliber was conceived to display its most interesing parts dial side. So it is not a big trouble.
