Entrepreneur Ahmed Abouhashima spotted wearing a Hublot

Ahmed Abouhashima, the Egyptian billionaire businessman and co-founder of Iwan Developments, has been photographed wearing a Hublot Spirit of Big Bang Full Sapphire chronograph — a watch that commands as much attention for its manufacturing complexity as for its retail price of $94,500. The sighting places Abouhashima in a relaxed indoor setting, the transparent sapphire case catching ambient light with the quiet confidence of someone accustomed to serious horology.

The Spirit of Big Bang Full Sapphire — reference 641.JX.0120.RT — measures 42mm (some 45mm variant references also exist across the range) and features a case, bezel, and caseback machined entirely from scratch-resistant sapphire crystal. The six H-shaped titanium screws anchoring the bezel are the only concession to metal on the exterior. Inside sits the HUB4700, a self-winding skeletonised flyback chronograph movement with approximately 50 hours of power reserve, its architecture deliberately exposed so that every rotor arc and column wheel operation is visible through all six faces of the case. The white structured rubber strap reinforces the all-transparent aesthetic without distraction.

Hublot introduced the Spirit of Big Bang line in 2014 as a tonneau-shaped counterpoint to the circular Big Bang, and the full sapphire iterations — launched progressively from 2016 — quickly became among the most technically celebrated pieces in the collection. Machining a sapphire monocoque case capable of withstanding chronograph pusher forces while maintaining water resistance is a process that generates significant waste and requires weeks of CNC time per unit, which explains the price point and the extremely limited production runs.

For collectors, the Full Sapphire occupies a specific niche: it is not a restrained dress watch nor a straightforward sports reference, but an exercise in material science worn on the wrist. Its market appeal crosses architecture, design, and engineering audiences in ways that few luxury watches manage. Grey-market premiums have remained modest relative to retail, reflecting decent but not frantic secondary demand.

Abouhashima's choice aligns with a broader regional taste among Gulf and Egyptian ultra-high-net-worth individuals for bold technical statements over conventional precious-metal complications. Paired here with a neck brace suggesting recent injury, the watch does the visual work of anchoring an otherwise clinical moment in unmistakable personal style.
