Swiss watch brand Hublot has revealed two new interpretations of its iconic Big Bang collection, which show the scope of the company's design and engineering capabilities. We are talking about the Square Bang Tourbillon 4-Day Power Reserve and Big Bang Unico Summer 2025 models. These premieres reflect Hublot's strategy of combining the traditions of high-end watchmaking with innovative materials and modern design.
Square Bang, launched in 2022, is the third form of the Big Bang collection after the classic round version and the Spirit of Big Bang line. The new model received a tourbillon and a completely redesigned rectangular mechanism architecture. The hand-wound calibre MHUB6023 is designed as a skeletonized structure, where the bridges form a clear geometric grid that enhances the sense of spatial architecture.

Special attention is paid to the power reserve: the extended four-day life significantly exceeds industry standards, which makes the model more functional for everyday use. The tourbillon's silicon escapement provides resistance to magnetic fields — a factor that is becoming increasingly important in the era of ubiquitous digital devices.
The Big Bang Unico Summer 2025 model reflects a completely different mood. It demonstrates Hublot's mastery of bright ceramics and serves as a symbol of the summer season. The design was inspired by the scenery and atmosphere of the Greek island of Mykonos. The color palette includes orange, sky blue and white-associations with sunsets, the Aegean Sea and beaches.
The case is made of orange ceramic with micro-jet treatment, combined with a blue bezel and white body elements. The watch is equipped with a One-Click quick-change strap system, which allows you to adapt the accessory to any event or style. A set of rubber straps in different colors enhances the versatility of the model and emphasizes its positioning as an accessory for leisure and active life.
Both new items illustrate the Hublot philosophy that has made the Big Bang collection one of the most recognizable in the world for two decades. Square Bang Tourbillon represents technological progress and the desire for new forms of mechanics, while Big Bang Unico Summer demonstrates the brand's boldness in color solutions and innovative materials.
For the watch industry, these models are becoming an indicator of global trends: the demand for complex mechanisms with architectural design and at the same time for emotional, bright accessories that emphasize the personality of the owner.
