Thrilling engineering all around
Voyeurism not infrequently accompanies enthusiasm for horological mechanisms. In particular it is men, and above all the subset of men with an affinity for technology, who want to see what’s going on inside their ticking microcosms. Curiosity is further piqued when a watch does more than put a pretty face on the time and date. Chronographs undoubtedly rank among watchmaking’s most attention-getting achievements, and special calibers of exclusive manufacture provenance spark delight through the functional interaction of diverse components. One excellent example of this is embodied in automatic Caliber HUB 1242 Unico, developed by Hublot, which boasts 72 hours of power reserve and includes a flyback chronograph. A look through the skeletonized dial allows the observer to discover a classic column wheel to control the chronograph’s various functions. The curious observer’s eye will also find an extraordinary double clutch for the chronograph mechanism. A 60-minute totalizer on the right-hand side of the dial tallies each revolution of the chronograph’s second hand, which is triggered by a button at the 2 o’clock position. A continually running second hand opposite the totalizer shows time’s passage, which never ceases even when the stopwatch has captured an elapsed interval. Closer scrutiny also reveals the skeletonized date ring. The back of this watch has much to offer as well: a ball-borne oscillating weight makes its revolutions here to supply the movement’s spring barrel with fresh energy when the watch is worn. A 72-hour power reserve ensures that the Big Bang Unico Magic Sapphire will still be running precisely after having spent a long week- end in a safe. Incidentally: this watch’s name defines its message: the bold 45 mm case rewards the 500 owners of this limited edition model with intriguing side views because the case, which is water-resistant to five bar, is crafted in polished sapphire crystal. Six titanium screws, each polished to a high gloss, connect the case’s several layers, while the crown and the chronograph buttons are also made from the antiallergenic material.
