This replica Big Bang 5207 45mm presents the Sang Bleu II collaboration in a grey ceramic case, a material choice that positions it between the stealth of black ceramic and the brightness of white. The 418.GX.5207.RX.MXM22 carries Maxime Plescia-Buchi’s geometric dial and bezel architecture in a Hublot material that few other watchmakers work with at this scale. At 45mm, the layered hexagonal geometry fills the wrist with angular facets that fragment light across matte grey surfaces.

Grey ceramic achieves its tone during the sintering process itself, making it a through-body color rather than a surface coating. Scratch resistance matches black and white ceramic variants, but the neutral grey provides a more muted visual presence.

Design & Finishing

The Sang Bleu II design language pushes further than the original Sang Bleu series. Overlapping geometric planes on the bezel and dial create a three-dimensional effect where the time display sits within a sculptural framework rather than beneath a flat surface. Grey ceramic softens the visual intensity compared to black, making the geometric details easier to read in mixed lighting. The matching grey strap blends with the case rather than contrasting against it, reinforcing a monochromatic palette. Compare this grey approach against the black Sang Bleu II 418.CX.1107.RX, which uses the same geometric architecture in a higher-contrast material. Both belong to the Big Bang range and share identical case geometry, separated only by color and the resulting mood.

On the Wrist

Grey ceramic at 45mm reads as modern and architectural without the aggressive contrast of an all-black watch. The material stays cool on initial contact and warms slowly, a characteristic shared across all ceramic references. Geometric facets catch ambient light at shallow angles, creating subtle shadow play across the bezel and dial plane. The monochrome grey palette makes this version more versatile with clothing choices than either black or white extremes. This replica Big Bang 5207 45mm offers the Sang Bleu II concept in the most balanced and neutral ceramic colorway available in the series.
