The chronograph mechanism is not the cam actuated variety but rather, Replica Hublot uses a column wheel chronograph which is better and has smoother action. The chronograph features a Flyback function, letting you stop and reset the stopwatch with the push of a button.
The chronograph uses a large central second hand which has a red tip. There are two sub-dials associated with the chronograph; there is a 30-minute counter at the 9 o’clock position; there is also a 12-hour counter at the 6 o’clock position.
These features are made possible by the in-house Hublot caliber UNICO HUB1270. The brushed King Gold case isn’t the only unique feature about this watch. A quick release system allows rapid strap changing with the push of a button located on the lugs of the Big Bang Unico Perpetual Calendar watch.
The watch is fastened to your wrist with a black rubber strap that has a ribbed texture and a black PVD coated titanium with an 18kt King Gold push-button clasp.
The skeletonized dial has incredible depth and features king gold-toned hour markers, as well as black sub-dials with white lettering and red markers. The Hublot Replica Watch rose gold-toned hands and hour markers have luminous fill and the perimeter of the dial has white printed numerals using a nice stencil style font with red printed minutes/seconds track.
The back side of the case uses a transparent sapphire crystal which lets you peer at the HUB 1270 movement; a 4Hz / 28,800 VpH automatic movement comprised of 46 jewels and 416 parts. This caliber can hold its power for approximately 72 hours straight when fully wound.
