Against the eggshell-coloured dial of the Master Ultra Thin Tourbillon watch, its new, larger hourmarkers with their gilded, honed silhouette are more eye-catching and easier to read than ever. They taper off at 6 o’clock and disappear altogether to make room for the Tourbillon to display itself, with its new gold bridge. On the back of the watch, the new mainplate of its automatic movement can be seen, decorated with a sunray finish.

10.77 millimetres – that’s how fine the new case is on the Master Ultra Thin Tourbillon, yet it can accommodate the Jaeger-LeCoultre Calibre 978G. This self-winding mechanical movement benefits from a 45-hour power reserve. Its Tourbillon draws the eye through a wide aperture at 6 o’clock, captivating the gaze with the play of full and empty spaces among its gear cogs.

Irreproachable rigour – expressed in the linearity of its hands and hour-markers – is a foil for the complex, intricate tangle of components that make up the Tourbillon. Its utterly sober pink gold case and eggshell dial are balanced by the generosity of a brown alligator leather strap.
