Housed in a 45mm grey titanium tonneau-shaped case measuring 14.45mm thick, this Spirit of Big Bang Meca-10 pairs a fixed grey titanium bezel over a black bezel base with a black rubber strap secured by a deployant buckle. The screw-down crown and scratch-resistant sapphire crystal — both front and through the transparent case back — complete a build rated to 50 meters of water resistance.
The transparent skeleton dial draws the eye directly to the movement beneath, framed by luminescent silver-tone index hour markers and minute markers along the outer rim. Luminescent hands sweep across the open architecture, while a small seconds sub-dial and a dedicated power reserve indicator round out the display.
Driving it all is the Hublot HUB1233 hand-winding movement, delivering a remarkable ten-day, 240-hour power reserve — the mechanical feat that defines the Meca-10 name. This example is offered complete with its original box and papers, and carries the Swiss Made designation.
