Hublot Spirit of Big Bang Moonphase Impact: Sapphire Diamonds, Osmium & All Black Edition Explained (2026)

The Hublot Spirit of Big Bang Moonphase Impact is a stunning display of innovation and craftsmanship in the world of luxury watches. This collection, introduced by Jean-Claude Biver, showcases Hublot's commitment to pushing boundaries and creating timepieces that are both functional and aesthetically captivating. The latest addition to the Spirit of Big Bang family takes inspiration from the iconic Big Bang Impact Bang of 2016, but with a revolutionary twist: diamonds set directly into sapphire crystal. This groundbreaking feature is a testament to Hublot's relentless pursuit of excellence and their ability to combine cutting-edge technology with timeless elegance.

One of the most striking models in the collection is the Sapphire Jewellery version. It features a 42mm tonneau-shaped case with a polished sapphire crystal, adorned with 54 fancy-cut diamonds set inside polished gold channels. The bezel is a masterpiece of craftsmanship, with laser-machined mounts holding the diamonds in place. The dial is a spectacle in itself, featuring 91 fancy-cut diamonds that practically eclipse the big date and moon phase complications. Despite the overwhelming sparkle, the hour, minute, and small seconds hands are equipped with lume, ensuring readability in various lighting conditions. This model is a limited edition of just 20 pieces, making it a highly exclusive and coveted timepiece for collectors.

The second model in the collection, the Sapphire, takes a different approach. It also features a 42mm tonneau-shaped case with a polished sapphire crystal, but instead of diamonds, it showcases sharp shards filled with crystallised osmium. Osmium, considered the rarest metal on Earth, is denser, harder, and heavier than platinum, and it possesses a natural bluish radiance. The crystallisation process, developed in collaboration with Swiss scientists in Valais, stabilises osmium and unlocks its cosmic sparkle. This model is a limited edition of 30 pieces, making it a rare and sought-after treasure for watch enthusiasts.

The third and final model in the collection is the All Black, a celebration of Hublot's 20 years of invisible visibility concept. It features a 42mm black ceramic case with a black ceramic bezel and dial, giving it a sleek and modern aesthetic. The impact motif is taken to the next level with the fragmented black ceramic bezel engraved and the dial featuring black-plated and polished appliques and hands with black Super-LumiNova. This model is limited to 100 pieces, making it more accessible but still highly desirable.

Under the hood, all three models are powered by the automatic HUB1770 skeletonised calibre, which boasts 288 components, 27 jewels, and a frequency of 4Hz. It provides a 50-hour power reserve and drives the moon phase display at 6 o'clock and the big date at 1 o'clock. The movement is a testament to Hublot's attention to detail and their commitment to precision engineering.

In conclusion, the Hublot Spirit of Big Bang Moonphase Impact collection is a testament to the brand's ability to create timepieces that are not only functional but also works of art. The use of diamonds set directly into sapphire crystal, the rare osmium shards, and the sleek All Black model showcase Hublot's innovation and their dedication to pushing the boundaries of what is possible in watchmaking. These timepieces are not just for telling time; they are for making a statement and leaving a lasting impression. As an expert in the field, I am in awe of Hublot's relentless pursuit of excellence and their ability to create timepieces that are both functional and breathtakingly beautiful.
