The Watch: The Hublot Spirit of Big Bang Moonphase (Ref. 647.NX.1137.RX) combines Hublot’s signature tonneau case design with an elegant astronomical complication. The result is a striking balance of industrial design and technical refinement.
The 43mm satin-finished titanium case is paired with a black skeletonized dial that reveals the mechanics beneath, including a large moonphase aperture at 6 o’clock, date ring display, and applied indices. The combination of polished titanium and skeletonized components gives the watch a sophisticated, architectural depth.
Inside beats the Hublot Caliber HUB1770, an in-house automatic movement with a 50-hour power reserve. The case features Hublot’s signature sandwich construction with a sapphire crystal on both front and back, ensuring full visibility of the movement’s detailing.
This example is fitted with a black rubber strap with deployant clasp, maintaining the bold yet comfortable character Hublot is known for.
Condition: Excellent condition overall. Light signs of handling only. Case, bezel, and crystal are clean with no notable marks. Movement runs accurately and all functions operate properly.
