This replica classic fusion 7170 pairs a blue sunray dial with a 42mm black ceramic case under reference 542.CM.7170.RX, creating an uncommon color-material combination within the range. Blue dials in the Classic Fusion lineup typically appear in steel or titanium cases, which makes the ceramic-blue pairing a deliberate departure from the usual material-color logic. The result is higher contrast: a deep blue surface framed by a matte black bezel and case. At 42mm the proportions stay moderate, avoiding the wrist dominance of the 45mm variants while providing more visual real estate than the 38mm references.

Technical Overview

• Case diameter: 42mm
• Case material: black ceramic
• Dial: blue sunburst
• Crystal: sapphire with anti-reflective treatment
• Strap: rubber with deployant clasp
• Movement: automatic
• Functions: hours, minutes, seconds, date

The blue sunray finish shifts between navy and cobalt depending on ambient lighting. Against the black ceramic frame, the dial appears to float rather than sit recessed, because the color contrast draws the eye inward rather than outward to the case edges.

Inside the Movement

An automatic caliber with date complication handles the mechanical duties behind a solid caseback. The date window at three o’clock uses a color-matched border to reduce visual interruption on the dial surface. Crown operation follows the standard Hublot pull-and-set configuration: first position for winding, second for date, third for time. The same movement platform appears across multiple Classic Fusion 42mm references, but the blue-on-ceramic presentation of the 7170 gives it a different personality than the carbon-dial or grey-dial alternatives. Compare this against the 525.NX.0170.LR in titanium for a material contrast study, or explore the wider Classic Fusion range to see how blue dials appear across different case materials.

What Sets It Apart

Blue-dial ceramic watches are uncommon because most ceramic models lean into the all-dark aesthetic. This reference breaks that pattern by introducing a saturated color into an otherwise monochrome case. The visual effect is more dynamic than a fully blacked-out piece, while the ceramic construction still delivers the scratch resistance and lightweight properties that define the material choice. This replica classic fusion 7170 offers the color-forward approach to ceramic that the rest of the 42mm ceramic catalog deliberately avoids.
