Aeternitas Mega 4 8888 MGA T CCR QPSE

From the outset, the primary aim of the AETERNITAS MEGA project was to produce an extremely" complex watch. The second stage of the project involved the quest for noble complications to enhance what was going to become a genuine technical feat, i.e. the most complex wristwatch in the world. The Research & Development department at Franck Muller Manufacturing focused on the volume and shape of the case, both essential aspects as regards the progress of the project. Then came the dial production, which proved to be quite a tricky operation, as space needed to be found to display almost all of the complications at the same time as retaining a high degree of legibility. When designing the various mechanisms, their graphical representation on the dial had to be taken into consideration to ensure perfect compatibility. Numerous problems were encountered when designing the mechanisms. However, one of the main difficulties experienced involved fitting the large Tourbillon into the space normally reserved for the Great Alarm. The other major difficulty was fitting the Great Alarm and its four hammers into a Curvex shaped case. Finally, the entire development of the secular date was a task that needed the highest level of watchmaking expertise. The basic movement has a Cintr'e Curvex shape. It's an automatic movement with a micro-rotor placed at 6 o'clock and visible through the open-back. It has a grand tourbillon (14mm) with a balance wheel with adjustment screws in platinum and no index. It has a Breguet spiral and a Franck Muller conception escapement. The movement is equipped with a double barrel: the first barrel guarantees a power reserve of about 3 days; the second barrel provides energy for the Sonnerie. Each barrel has its own power reserve displayed on the dial."
