Hublot Big Bang Joyful Steel Purple: Amethyst Gemstones Complete the Color Spectrum

Hublot Big Bang Joyful Steel Purple: Amethyst Gemstones Join the Color Revolution

At Watches & Wonders 2026, Hublot expanded its successful Joyful collection with a new amethyst-set variant. The Big Bang Joyful Steel Purple (ref. 485.SV.2210.RX.1205) adds a sixth gemstone colorway to the lineup that debuted in 2025, completing what the brand describes as a full spectrum of mood-expressing timepieces.

Gemstone Bezel: 36 Amethysts at 380-450 Nanometers

The defining feature of the Big Bang Joyful Steel Purple is its bezel set with 36 amethyst gemstones. Amethyst sits at the highest frequency of visible light — between 380 and 450 nanometers — at the very edge of what the human eye can perceive. Hublot leverages this unique optical property to create a watch that appears to pulse with deep purple energy.

Case Architecture: The Big Bang DNA

The 33mm stainless steel case maintains the architectural, layered construction that defines the Big Bang silhouette. Satin-finished and polished surfaces create visual depth, while the iconic H-screws punctuate the bezel. The case measures 10.55mm thick and offers 100 meters of water resistance — practical capability that many dress-oriented gem-set watches lack.

The One Click strap-change system allows tool-free swapping between the two included straps: a white-lined rubber strap with amethyst purple central insert matching the bezel stones, and a plain white rubber alternative.

Technical Specifications

The Joyful Collection: A Complete Color Spectrum

The Big Bang Joyful collection now spans six gemstone references, each offering a distinct mood and color profile. The Purple Amethyst joins the existing lineup that includes pink, blue, green, yellow, and orange variants. Each model uses the same 33mm steel case platform with color-matched gemstone bezels and coordinating rubber straps.

Movement: Sellita-Based Reliability

Powering the Steel Purple is the HUB1120 self-winding movement, based on the Sellita SW100-1a architecture. Running at 28,800 vph with 18 jewels and a 40-hour power reserve, this caliber prioritizes reliability and accuracy for everyday wear. The sapphire case back with anti-reflective treatment reveals the polished and microblasted tungsten rotor.

Market Positioning: Accessible Luxury with Character

At $15,500, the Big Bang Joyful Steel Purple occupies an interesting position in Hublot's catalog. While marketed primarily as a women's watch, the 33mm format works across wrist sizes. The amethyst colorway offers a richer, deeper alternative to the brighter gemstone options already in the collection, appealing to collectors who prefer darker, more saturated hues.

FAQ

Can men wear the Hublot Big Bang Joyful collection?

Absolutely. While Hublot positions the 33mm Joyful models as women's watches, the Big Bang silhouette and bold gemstone bezels work well on various wrist sizes. The reviewer at aBlogtoWatch tried it on a 7.5-inch wrist and noted it was "a fun watch even on my 7.5\" wrists." The One Click strap system also makes it easy to find alternative straps for different styling preferences.

What gemstones are available in the Joyful collection?

The complete collection features six gemstone options: pink (rubellite), blue (sapphire), green (tsavorite), yellow (citrine), orange (spinel), and the new purple (amethyst). Each uses natural gemstones set in a color-matched bezel on the same 33mm stainless steel case platform.

How does the One Click system compare to other quick-change mechanisms?

Hublot's patented One Click system is widely considered one of the best quick-change strap systems in the luxury watch industry. The trapezoid push-buttons on the lugs allow instant, tool-free strap swaps, and the system has been refined over multiple Big Bang generations to offer reliable, secure connections.
