H Big Bang INTEGRATED SKY BLUE CERAMIC Ref# 451.EX.5120.EX
Model: H Big Bang Integrated Sky Blue Ceramic – 42 mm, Ref. 451.EX.5120.EX
Case & Bezel
The Big Bang Integrated Sky Blue Ceramic stands out with a 42 mm case crafted entirely from polished and satin-finished sky-blue ceramic, giving it a lightweight yet highly durable structure. The integrated case design flows seamlessly into the bracelet, while the fixed bezel—also in matching sky-blue ceramic—is secured by six iconic H titanium “H” screws, reflecting the brand’s unmistakable DNA.
Dial & Hands
The skeletonized dial reveals the contemporary architecture of the movement, highlighted with rhodium-plated index markers and hands coated with Super-LumiNova for readability in all conditions. The open-work design adds depth and sophistication while maintaining excellent legibility.
Chronograph & Date Functions
Equipped with a flyback chronograph function, the watch features a central chronograph seconds hand, a 60-minute counter at 3 o’clock, and a small-seconds sub-dial at 9 o’clock. The date display is integrated into the chronograph counter at 3 o’clock for a sleek, unobtrusive look.
Movement
At its heart is the in-house HUB1280 UNICO automatic flyback chronograph caliber. This column-wheel movement beats at 28,800 vibrations per hour, incorporates 43 jewels, and provides an impressive 72-hour power reserve.
Bracelet & Clasp
The integrated bracelet is made entirely of sky-blue ceramic with alternating polished and satin finishes, ensuring both comfort and a bold aesthetic. It fastens securely with a titanium deployant buckle clasp.
Crystal & Caseback
The watch is protected by a sapphire crystal with anti-reflective coating on both sides, and features a transparent caseback offering a clear view of the UNICO movement.
Water Resistance
Water resistant to 100 meters (10 ATM), making it suitable for everyday wear and light aquatic use.
