Hublot and Ahmed Seddiqi introduced two commemorative Big Bang watches at Dubai Watch Week 2025: the Big Bang All Black Ahmed Seddiqi 75th Anniversary and the Big Bang Titanium Grey Ahmed Seddiqi 75th Anniversary. The collaboration marks 20 years of Hublot’s Big Bang and 75 years of Ahmed Seddiqi & Sons. Release coverage reports the All Black as limited to 10 pieces; detailed specifications for the Titanium Grey have not been established in the available coverage.
What the two anniversaries mark
The watches bring together two milestones in the 2025 release context: the Big Bang’s 20th anniversary and the 75th anniversary of Ahmed Seddiqi & Sons. The two models were presented in connection with Dubai Watch Week 2025. The Hour Markers describes Arabic numerals and an oscillating weight engraved with Seddiqi’s anniversary insignia as commemorative cues shared by the pair.
The two editions
| Edition | What release coverage establishes |
|---|---|
| Big Bang All Black Ahmed Seddiqi 75th Anniversary | Reference 431.CI.1340.RX.SDQ25; reported as a 10-piece limited edition. Available coverage describes its black ceramic construction and dark, Arabic-numeral dial. aBlogtoWatch search-result coverage and a Channel NewsAsia excerpt report the limited run. |
| Big Bang Titanium Grey Ahmed Seddiqi 75th Anniversary | The model name and its place in the anniversary pair are confirmed by The Hour Markers. Detailed materials, reference, edition size, and price are not stated in the cited coverage. |
The names indicate a visual distinction, but available coverage does not provide a complete, like-for-like specification sheet. In particular, details reported for the All Black should not be assumed to describe the Titanium Grey.
What is reported about the All Black
The All Black’s reference is reported as 431.CI.1340.RX.SDQ25. aBlogtoWatch’s search-result excerpt describes a microblasted black ceramic case, black-finished titanium crown and pushers, and H-shaped screws. It reports a 43 mm by 13.2 mm case format and 100 m water resistance for the pair; aBlogtoWatch’s article could not be accessed directly, so these figures are reported specifications rather than independently confirmed manufacturer data.
#1 Best Overall
- Made of non-allergic natural resin, waterproof, soft, light, durable, comfortable to wear
- It is suitable for Hublot Big Bang 25 * 19 * 22mm interface watch band , not for other watches
- It is very important to choose the correct model. To avoid the trouble caused by the return and exchange of goods, if you have any questions about the model and size of the watch, please feel free to contact us
- Package included: 1 * Rubber strap (without metal buckle), 1 * tool kit, easy replacement with our free tools. The watch has a new look! It is not the original and is a good substitute
The same coverage describes a checkerboard-like “Carbon Effect” dial with large Eastern Arabic even-hour markers, Eastern Arabic numerals on the date and chronograph displays, and black tone-on-tone hands and dial elements. It also reports a textured black rubber strap and a folding clasp made from black-finished titanium and black ceramic.
There is a notable contrast between the predominantly black exterior and the movement visible through the sapphire caseback: Channel NewsAsia reports a 22k solid rose-gold oscillating weight engraved with Seddiqi’s anniversary insignia. That detail is reported for the All Black and should not be extended to the Titanium Grey without a supporting specification.

What is—and is not—known about specifications and availability
The Hour Markers confirms the Titanium Grey model and the pair’s commemorative cues, but does not give its detailed specification, reference, production quantity, or price. Current stock and retail pricing for either edition are not established by the cited release coverage. The All Black’s reported 10-piece limit is a production figure, not evidence that any example remains available.
Ahmed Seddiqi’s official 75th-anniversary limited-editions collection provides broader anniversary context, but its listed editions do not independently verify the Big Bang models. For a purchase inquiry, confirm the exact reference, price, and availability directly with Hublot or an authorized retailer.
