Unusual time display
HYT - H1
The hour on this futuristic timepiece is displayed by a tube of fluorescent liquid - activated by two bellows each driven by a piston - running along the perimeter of the 48mm case. The seconds are indicated by a rotating wheel at the 9.30 position of the unstructured dial, the power reserve of 65 hours is shown by a fan-shaped indicator at the 2.30 position. It is crafted in various materials such as titanium and pink gold. Prices range from HK$370,000 to HK$553,000.
Christophe Claret - X-TREM-1
The retrograde hours and minutes display of this titanium timepiece is generated by magnetic fields instead of mechanical connection. Two 4mm hollow spheres are encased in the cylindrical sapphire tubes on the two sides of the case. Driven by magnetic carriages, the two spheres glide along the tube following a durable silk thread to indicate the time using the Super-LumiNova painted graduations. The seconds are displayed on the tourbillon cage, which also offers a glimpse of the flying tourbillon at work. It has a power reserve of more than 50 hours and is water resistant to 30 metres. It costs HK$2 million and comes in white gold, rose gold, and platinum.
MB&F - Moon Machine
The HM3 Frog timepiece has been interpreted by Finnish watchmaker Stepan Sarpaneva, who incorporated his iconic moon-phase indicator in this model (HK$785,000). The time is shown by two stationary pointers atop two aluminium domes - one of which rotates every 12 hours and the other every 60 minutes. These are housed under the 'frog eyes'. The moon phase indications feature a northern sky rotor as the backdrop. The Moon Machine is available in three styles - natural titanium, black titanium, and red gold, with matching moons and sky backdrops - with 18 pieces each.
