This timekeeping masterpiece is as beautiful as it is light, it’s packed with mechanical, creative and artisan talents and is an ode to the past, namely the first foray into aeronautics so-dear to Zenith. This limited edition piece (5 available) is brought to life by the manual wind 5011K calibre which has been painstakingly openworked with a fretsaw and both sides can be admired through the two sapphire covers which hold it in place. This pocket watch movement powers the central hours and minutes with two openwork hands in blue-tone gold, small seconds at 9 o’ clock and 48-hour power reserve indicator at 3 o’ clock. The case is a true sapphire setting with fabulous measurements (60mm diameter) topped by a hand-engraved blue-enamelled gold bezel and fitted with a large ratcheted crown, a signature feature on pilot watches. The lugs linking the case to the strap have also been sculpted. Price: 200,000 CHF
