Product Details
The JJ+ atelier's 42mm Big Bang replica is one of the most technically ambitious in the market, engineered with a focus on details that serious collectors scrutinise. The movement carries internal steel stamps matching SW300 spec, and the dial's applied hour-markers feature the brand's signature pointed-and-chamfered "wheat-head" indexes, electroplated in white gold finish so they catch light from every angle. The case is CNC-machined and hand-finished with alternating mirror-polish and sandblast zones that closely mirror the original's complex surface treatment. The bezel is secured with six titanium H-screws, and the rubber strap was developed from a mould derived from a premium Hublot strap -- an expensive process revised four times to nail the correct logo font.

Frequently Asked Questions
What movement is inside the JJ+ edition and is it automatic?
Yes, the JJ+ edition uses an automatic movement that winds through the rotor. It runs without needing a battery and can also be manually wound.
Is the case material titanium or stainless steel?
The case on this rep uses a titanium-tone finished stainless steel to replicate the look of the retail version, giving it a light grey tone while maintaining durability.
Does the skeleton dial face match the retail layout accurately?
Yes, the bridge layout, sub-registers, and skeletonized dial design are closely mirrored from the retail reference. It is one of the stronger points of this edition.
