Aftermarket Rubber Strap for Hublot King Power Big Bang Series – 28x20mm

Description

Two of Hublot’s most imposing references, one precise lug specification. The King Power and Big Bang share the 28x20mm taper in certain of their variants — a wide, substantial geometry that demands a strap built specifically for it rather than adapted from something narrower. The Hublot King Power / Big Bang Rubber Strap is that strap: high-quality rubber, a proportionally correct 28x20mm taper, and a folding buckle that holds the watch securely through everything these references were designed to handle. Sleek, functional, and built to last.

28x20mm Rubber. Built Wide Enough to Mean It.

• High-quality rubber for long-lasting flexibility — the rubber is chosen specifically for its combined performance across two axes: flexibility that keeps it comfortable through a full range of wrist movement without creasing or pulling, and durability that holds its profile, colour, and structural integrity across years of daily wear. No softening at the fold, no surface cracking under UV — just consistent, dependable performance from the first wear to the last.
• 28x20mm taper — the specification these references share — built from 28mm at the case outward and tapering to 20mm at the buckle end, the strap is engineered to the exact geometry of the King Power and Big Bang variants that use this lug width. It seats flush at the case with no gap and tapers proportionally along its length — a fit that only a correctly specified strap delivers.
• 115mm + 85mm length — the 115mm long side accommodates the broader wrist range that watches of this presence naturally attract, while the 85mm short section provides reliable adjustability without the tail overrunning the keeper. Sized for the wrist the watch deserves.
• Folding buckle closure — the secure, flat-sitting closure that a strap of this width calls for. It locks with confidence, opens single-handed, and distributes closure tension evenly across the 20mm buckle-end width — keeping the strap secure and the wrist comfortable through active, all-day wear.

For the King Power and Big Bang That Needs a Proper Rubber Option.

At 28x20mm, the aftermarket narrows considerably. Most rubber straps for Hublot are built around the more common 25x19mm specification, leaving the 28x20mm King Power and Big Bang references without a correctly proportioned rubber option. This strap fills that gap — the right width, the right taper, and the right construction for two watches that have always rewarded being worn hard.

This strap is the right choice for:

• King Power and Big Bang owners with 28x20mm lug variants who have found the aftermarket defaulting to specifications that don’t fit their references correctly.
• Active wearers who use these watches in sport, outdoor, or water environments where rubber outperforms leather entirely — no maintenance, no degradation, no hesitation before getting it wet.
• Owners rotating rubber alongside a bracelet or leather strap who want the correct-width rubber option for active days without sourcing three different products.
• Detail-focused buyers for whom the 28mm-wide case end on the strap matters as much as the lug width measurement — a strap that fills the lug fully rather than leaving visible gaps.
