Hublot Big Bang Unico King Gold 441.OM.1180.RX 43mm 1:1 Replica by LS Factory

Big Bang Unico King Gold, Recreated

This LS Factory 1:1 replica pays tribute to the Hublot Big Bang Unico King Gold 441.OM.1180.RX, one of the brand’s most recognizable modern luxury sports chronographs with its fusion of warm red‑toned gold and stealthy black ceramic.[0]

The genuine reference pairs a bold skeletonized dial and Unico in‑house chronograph movement with a sporty rubber strap, creating a watch that feels equally at home with a sharply tailored jacket or a minimalist streetwear look.[0] LS Factory captures this character in a 43mm homage that keeps the drama and detail of the original while tailoring it for accessible, worry‑free daily wear.

Authentic Reference & Core Specifications

The real Hublot Big Bang Unico King Gold 441.OM.1180.RX belongs to the Big Bang Unico family, featuring an in‑house HUB1280 automatic flyback chronograph movement with a skeletonized dial and open date display.[0] The OEM piece typically measures about 42 mm in diameter, crafted in Hublot’s proprietary red‑toned King Gold alloy with a black rubber strap and ceramic bezel.[0]

The official specification highlights include an automatic chronograph caliber with flyback function, approximately 72 hours of power reserve, and 10 ATM (100 m) water resistance, along with a sapphire crystal and exhibition caseback to showcase the movement.[0] This LS Factory interpretation stays visually faithful to that blueprint while using robust materials and a HUB1280 clone movement to deliver the same skeletonized aesthetic and functional chronograph experience.

Key Specifications

Case, Bezel & Wrist Presence

The first thing you notice on the wrist is the unique shade of King Gold: a richer, redder tone than ordinary rose gold, designed to echo Hublot’s proprietary alloy and its use of platinum to deepen the color.[0] LS Factory applies a thick 18k PVD gold plating on a 316L steel base, combining the visual drama and weighty feel of gold with the durability and value of stainless steel underneath.

The updated 43 mm case uses a new mold that wears cleaner and more compact than older 44 mm versions, with shorter lugs and integrated pushers that help the watch sit snugly even on wrists around 17 cm. The brushed surfaces on the case front contrast with polished bevels along the edges, underscoring the layered, architectural Big Bang design language that has become synonymous with Hublot’s modern era.[0]

Dial, Movement & Performance

At the heart of this homage is a HUB1280 clone automatic chronograph movement, echoing the structure and layout of the genuine Unico caliber used in the original 441.OM.1180.RX.[0] The openworked dial exposes the date ring and key gear train components, giving you a constant view of the mechanical choreography usually hidden behind a solid dial.

The chronograph is fully functional: the central seconds hand starts smoothly from the top pusher, stops precisely, and snaps back in a flyback‑style reset using the lower pusher. The movement is tuned for a power reserve of around 72 hours in typical use, so you can take the watch off for a day or two and still find it running when you pick it up again.

LS Factory also focuses on visual correctness, with a properly positioned, non‑sunken date window at the edge of the skeletonized display to mimic the look and legibility of the genuine Big Bang Unico dial.[0] Applied indices, bold hands, and layered sub‑dials reinforce the technical, high‑performance feel that enthusiasts expect from this design.

Strap, Comfort & Styling

This replica includes a high‑quality black structured rubber strap that mirrors the sporty, integrated look of the OEM model’s rubber bracelet.[0] The rubber is supple yet supportive, allowing the 43 mm case to hug the wrist without feeling top‑heavy or cumbersome.

A one‑click quick‑change system lets you release the strap with minimal effort, so you can swap to alligator‑pattern, colored, or hybrid straps in seconds to match business, smart‑casual, or weekend outfits. Paired with a secure deployant‑style clasp, the watch feels solid on the wrist while remaining easy to take on and off throughout the day.

On the style front, the combination of King Gold tone, black ceramic bezel, and skeletal dial delivers instant visual impact, making this an ideal choice if you want a stand‑out piece that still works with monochrome tailoring or minimalist streetwear. It is bold, contemporary, and distinctly modern‑luxury, without being tied to the price and delicacy of a full solid‑gold original.

Everyday Use & Practical Details

While the genuine 441.OM.1180.RX offers 10 ATM water resistance suitable for everyday splashes and light swimming,[0] this 1:1 homage is best treated as water‑resistant for daily wear only, avoiding prolonged immersion or high‑pressure water exposure. The ceramic bezel is exceptionally hard and scratch‑resistant, giving you real‑world protection against marks from keys, zippers, and desk wear.

The gold‑tone PVD coating is significantly more durable than traditional flash gold plating and is designed to keep its deep, red‑gold hue for years with normal care. Avoid harsh chemicals, abrasive polishing cloths, and repeated impacts to maximize longevity. With these habits, the watch can remain a dramatic yet reliable part of your rotation for both day and night occasions.
