The “Big Dipper” Reverso

A steel Reverso built around a double dial with a 24-hour display, its specially made blue starburst dial mapping the stars of the Big Dipper (Ursa Major) across the face rather than showing a conventional astronomical complication. Case No. 2’190’694, dated by Christie’s to circa 2000. The kind of one-off constellation dial that turns a Reverso into something closer to a wearable star chart than a watch.
