At the heart of the 2790 SQ is a massive tourbillon at 6 o’clock. The cage is Vacheron’s signature maltese cross shape, suspended from a large, imposing bridge. Above that, you’ll notice the hour and minute hands are anchored just off-center, slightly above the dial’s true center, making more room for the tourbillon (which doubles as the small-seconds display). To the right of the hands is a transparent disk marked with the days of the month for the date display. It’s there when you need it, but it doesn’t take any visual prominence away from the beauty of the movement. There is also a subtle power reserve indicator barely visible across at 10 o’clock, again kept restrained to avoid distracting from the caliber.
