The Hublot BIG BANG 645.JB.4934.RX pairs a tourbillon with a 42mm sapphire case, introduced in 2025. This manual-winding timepiece features a skeleton dial and houses the HUB6020 caliber.
The sapphire crystal protects the dial, while the exhibition case back reveals the internal movement. The watch provides a water resistance of 30m and is secured on the wrist with a folding clasp. This timepiece is produced as a limited edition of 20 pieces.
When purchased from Aristo Watch, this watch comes with access to Aristo Care. A pre-owned watch should not come with less support than a new one, so Aristo Watch extends an additional year of movement inspection or servicing beyond the manufacturer's warranty.
