JJZ Factory Hublot Classic Fusion 542.CM.1171.JJZ 42mm Ceramic
The JJZ Factory Hublot Classic Fusion 542.CM.1171.JJZ is a 42mm black ceramic watch featuring a brushed ceramic bezel, six H-shaped titanium screws, an automatic mechanical movement, and an exhibition caseback.
The model combines the restrained proportions of the Classic Fusion collection with a predominantly black ceramic exterior. Different dial configurations introduce carbon-style, blue sunburst, and textured black finishes, while the strap system combines rubber with a leather-style upper section on selected configurations.
Its mechanical movement provides an approximate 42-hour power-reserve specification.
42mm Black Ceramic Case
The 542.CM.1171.JJZ uses a 42mm black ceramic case.
Ceramic provides a hard exterior surface with strong resistance to ordinary surface scratching compared with many conventional polished metal surfaces.
The dark case also creates a continuous visual relationship between the bezel, dial, strap, and other black exterior components.
As with other ceramic watch cases, the material should still be protected from severe impacts, particularly around exposed case and bezel edges.
Brushed Ceramic Bezel
The bezel uses black ceramic with a brushed surface treatment.
Rather than relying entirely on a high-gloss ceramic appearance, the directional brushing introduces a more technical texture across the bezel.
This finish becomes particularly noticeable as light moves across the surface and provides contrast against other case components.
Six H-Shaped Titanium Screws
Six exposed H-shaped titanium screws are positioned around the bezel.
These screws create one of the most recognizable geometric elements of the Classic Fusion exterior and provide a metallic contrast against the black ceramic.
The combination of ceramic and titanium also reinforces the mixed-material construction used throughout this configuration.
Multiple Dial Configurations
The 542.CM.1171.JJZ is available with several distinct dial treatments, allowing the same 42mm ceramic architecture to take on different visual characteristics.
The supplied configurations include:
1. Carbon-style dial
2. Blue sunburst dial
3. Matte black textured dial
4. Black dial configuration with exhibition movement presentation
The carbon-style option emphasizes a technical appearance, while the blue sunburst version changes noticeably according to lighting direction.
The matte black textured configuration provides a more restrained monochromatic appearance against the black ceramic case.
Automatic Mechanical Movement
The watch is equipped with a HUB1110 automatic mechanical movement.
Its supplied power-reserve specification is approximately:
42 hours
The automatic winding system uses normal wrist movement to provide energy to the mechanical movement during wear and also supports manual winding through the crown.
Exhibition Caseback
The watch incorporates an exhibition caseback, allowing the mechanical movement to remain visible from the rear.
This creates a clear contrast between the relatively restrained Classic Fusion dial architecture and the mechanical components visible through the back of the watch.
Rubber and Leather-Style Strap
Selected configurations combine a rubber strap structure with a leather-style upper surface.
The rubber component provides flexibility where the strap follows the wrist, while the upper section introduces a more traditional texture that complements the comparatively understated Classic Fusion case design.
A softer rubber strap configuration is also available.
Titanium Folding Clasp
The strap is secured by a titanium folding clasp with an IP-applied surface finish.
The folding construction provides a secure closure while maintaining the technical material theme established by the ceramic case and titanium bezel screws.

Ceramic and Titanium Construction
One of the defining characteristics of this JJZ Classic Fusion is its combination of black ceramic and titanium components.
The ceramic case and brushed ceramic bezel establish the dark exterior, while the six titanium H-shaped bezel screws introduce small metallic details around the front of the watch.
A titanium folding clasp continues the mixed-material construction on the strap side.
This combination creates a distinctly different appearance from stainless steel Classic Fusion configurations while retaining the relatively simple case and dial proportions associated with the collection.
Brushed Ceramic Surface
The brushed treatment is particularly relevant to the appearance of the bezel.
Directional finishing reduces the uniformly glossy appearance commonly associated with ceramic and introduces visible surface lines that respond differently to direct and indirect light.
This creates subtle variation across an otherwise predominantly black exterior.
Wearing and Care
The 42mm case gives this Classic Fusion balanced proportions for everyday wear while retaining a substantial presence on the wrist.
Ceramic is highly resistant to ordinary surface scratching, but it should not be treated as impact-proof. Strong impacts against hard surfaces should be avoided, particularly around case and bezel edges.
Use a clean microfiber cloth for routine cleaning. Abrasive polishing materials should not be used on the brushed ceramic surfaces because they may alter the directional finish.
The mechanical movement should also be protected from strong impacts and powerful magnetic fields.
