Designed by tattoo artist Maxime Plescia-Buchi, this replica big bang 5107 blue carries reference 418.EX.5107.RX.MXM21 and represents the second generation of the Sang Bleu collaboration. The Sang Bleu II replaced the original’s hexagonal geometry with a more complex three-dimensional case construction where overlapping geometric planes create the indices and hour markers. At 45mm in titanium (EX designation), the case features angular facets across its surface that catch light in sharp, unexpected ways. The blue dial treatment adds depth to the already complex geometry.

Build Details

• Case diameter: 45mm
• Case material: satin-finished titanium
• Bezel: geometric faceted titanium with applied markers
• Crystal: sapphire
• Dial: blue with overlapping geometric planes forming indices
• Strap: black rubber with titanium deployment clasp
• Movement: automatic
• Functions: hours, minutes, seconds

The Sang Bleu II geometry means that hour markers are not printed or applied in the traditional sense. Instead, the three-dimensional construction of the dial itself creates the reference points for reading time, making this a fundamentally different design approach from any standard Big Bang.

What Collectors Notice

The Maxime Plescia-Buchi collaboration has produced several colorways across both Sang Bleu generations, and collectors track the differences closely. This blue version (5107 reference) uses a cool-toned palette that emphasizes the angular geometry through shadow play. The overlapping diamond-shaped planes create depth that photographs cannot fully capture. Under changing light, the blue shifts between navy and steel tones depending on the angle. Compare this against the white 418.HX.2001 Sang Bleu II to see how the same geometric platform transforms under a different color treatment. Both live within the Big Bang family as limited collaboration pieces.

This vs Other Versions

Among the Sang Bleu II colorways, the blue version sits between the high-contrast black edition and the subtle white version in terms of visual impact. Blue gives the geometric facets enough tonal variation to read as dynamic without the stark drama of black. The titanium case keeps weight low at 45mm, and the satin finish adds a muted industrial quality that supports rather than competes with the dial geometry. For anyone tracking the hublot big bang sang bleu evolution, the MXM21 generation represents the more refined, architecturally complex chapter. This replica big bang 5107 blue puts that collaboration design into a color that balances artistry with everyday wearability.
