Inside the watch is a still fairly new movement from Hublot known as the HUB6035 caliber. This skeletonized movement presents the time with a tourbillon regulation system as well as a micro-rotor automatic winding system. Replica Hublot designed the movement for aesthetics and did a great job of “hiding” the automatic rotor on the barrel which sits just below the 12 o’clock hour indicator. The automatic rotor is also where the "Hublot" branding is on the dial, so it's quite fun to watch it spin while you wear the watch on your wrist. The Hublot HUB6035 caliber operates at 3 Hz with 72 hours of power reserve and is produced from 243 parts.
The readability on the dial is also very good. Few brands next to Hublot have the sheer experience of skeletonized dials and how to make them both cool and readable. Replica Hublot has been doing this for as long as I can remember and achieves prominent hands and indexes, subdued coloring and proper replica watches surface finish. The result is a perfectly readable dial yet offers a complete skeleton/transparent experience for viewing pleasure. Additional pieces of sapphire crystal are additionally used in the dial and for parts of the movement bridges to further enhance the “see through” effect that Hublot is aiming for. What’s next for sapphire crystal watches? Colors. Synthetic sapphire is actually easier to color with different shades than ceramic. Hublot and some of its contemporaries have already started to play with different colors of sapphire crystal.
