JJ+ factory 1:1 Hublot Big Bang 42mm - HB1110-architecture movement with steel stamp, sapphire anti-reflective crystal, titanium H-screw bezel, and laser-engraved "wheat-head" logo.
JJ+ has long been respected for refusing to take shortcuts, and their 42mm Hublot Big Bang is a showcase of that philosophy. The movement inside is built to the HB1110 specification, confirmed by matching the original's internal steel stamp and matching Swiss-import English markings - no adhesive overlays. The HUBLOT "wheat-head" logo on the hands is laser-engraved by a specialist facility rather than applied as a sticker, producing a crisp, permanent mark visible under magnification. The bezel is fitted with six titanium H-shaped screws. The anti-reflective sapphire crystal minimizes glare from any angle. Dial variants include blue, grey, and green (print plus radial brush), black (sandblast plus print), and white (sand-white spray plus print). Case surfaces are CNC-machined in Switzerland-standard tooling with alternating high-polish and brushed finishing. The rubber strap was developed from a US-sourced original reference, with four rounds of tooling revision to match the HUBLOT lettering on the clasp wings.
The 42mm is Hublot's more refined everyday size, sitting comfortably on wrists in the 6.5 to 7.5 inch range. It is less imposing than the 44mm or 45mm but still has strong presence.
Yes, the Big Bang uses a standard lug system. Compatible aftermarket straps in Hublot lug widths are widely available and can be swapped with a standard spring bar tool.
Yes, the subdials are functional. The movement drives the registers as displayed on the dial. The chronograph pushers (if applicable to the variant) are operational.
