Hublot Big Bang Perpetual Calendar 406.NM.0170.RX Skeleton Index Black Ceramic Bezel & Titanium Case Rubber 45mm BRAND NEW

The Hublot Big Bang Perpetual Calendar 406.NM.0170.RX is one of the most compelling expressions of complication watchmaking within the iconic Big Bang family. Since Hublot introduced the Big Bang in 2005, the collection has stood as a symbol of the brand's "Art of Fusion" philosophy — merging unconventional materials, bold proportions, and sophisticated movements into watches that are equally at home at a black-tie event and in an active lifestyle. The Perpetual Calendar variant elevates that vision further by housing one of horology's most revered complications — the perpetual calendar — inside the collection's signature cushion-shaped case architecture.

At 45mm in diameter, the titanium case of the 406.NM.0170.RX makes an assertive statement on the wrist without sacrificing comfort. Titanium is prized in fine watchmaking for its exceptional strength-to-weight ratio, its natural resistance to corrosion, and its hypoallergenic properties — qualities that make a large-format watch like this far more wearable across extended periods than a steel or gold equivalent of the same dimensions. The satin and polished finishing on the case integrates the multiple components and exposed screws that are a hallmark of Big Bang case design.

The black ceramic bezel frames the dial with a deep, lustrous contrast that ceramic does better than almost any other material. Ceramic is extraordinarily scratch-resistant and retains its rich color and surface finish over decades of daily wear, making it a practical as well as aesthetic choice. The bezel's bold profile echoes Hublot's characteristic integration of fine materials in unexpected pairings, a defining element of the Art of Fusion ethos.

The skeleton index dial is the visual centerpiece of this reference. By opening the dial to reveal the perpetual calendar mechanism beneath — displaying day, date, month, and leap-year cycle — Hublot transforms a highly functional complication into a three-dimensional exhibition of mechanical artistry. Indices provide legibility anchors across the openworked landscape, ensuring the watch remains readable despite its architectural transparency. The perpetual calendar itself is one of watchmaking's most admired complications because it autonomously accounts for months of varying lengths and leap years, requiring virtually no manual date correction until the year 2100.

A rubber strap completes the configuration of the 406.NM.0170.RX, reinforcing the Big Bang's sport-luxury DNA and providing a secure, comfortable fit suited to a watch of this size and presence. Hublot's proprietary rubber is renowned for its durability, flexibility, and refined texture, and it serves as an ideal pairing for a titanium-cased tool-inspired grand complication. This reference is offered brand new, making it the ideal choice for a collector seeking an unworn example with full manufacturer warranty coverage.
