          Description

          【Case Construction】
          • Reference-based specification: 42 mm tonneau-shaped case in microblasted black ceramic, based on Hublot Reference 642.CI.0170.RX. The reference is listed with black ceramic case, black ceramic bezel, sapphire crystal, 100 m / 10 ATM water resistance, and black rubber strap.
          • The tonneau case shape gives the watch a more architectural and aggressive profile than the round Big Bang line.
          • The black ceramic construction creates a stealthy, modern, and technical appearance.
          • The exposed H-shaped screws preserve Hublot’s industrial design identity.

          【Dial Highlights】
          • The skeleton dial exposes the chronograph movement architecture, giving the watch strong mechanical depth.
          • Large Arabic numerals, baton markers, and luminous hands maintain readability despite the openworked structure.
          • The black and silver color palette reinforces the Black Magic theme.
          • The three-register chronograph layout adds practical sports timing functionality.

          【Crystal】
          • Sapphire-style crystal provides strong clarity and scratch resistance.
          • The crystal gives a clear view of the skeletonized dial, sub-dials, and movement layers.
          • Its anti-reflective visual treatment supports readability from different angles.

          ⸻

          【Movement】
          • Powered by a HUB4700-style self-winding skeleton chronograph movement, commonly associated with this reference, with approximately 50 hours of power reserve.
          • Functions include hours, minutes, chronograph timing, and date display.
          • The movement layout supports both sports functionality and openworked visual appeal.

          ⸻

          【Strap & Clasp】
          • Paired with a black structured rubber strap.
          • The strap matches the black ceramic case and keeps the watch sporty and comfortable.
          • Deployant-style clasp provides secure daily wear.
