Rado Watch DiaMaster Power Reserve R14137156. For the Rado DiaMaster Power Reserve watch, the luxury Swiss watch manufacturer combines their legendary high-tech ceramic material with an unusual dial layout. At the centre of the ink black sunburst finished dial are three sleek silvered hands for the hours, minutes and seconds while at 9 o’clock, a separate subsidiary dial displays the power reserve. The power reserve dial is detailed with a railway-style track to display the luxury watch’s remaining power of up to 80 hours. A vivid marking in red aims to warn you when the timepiece is running low. Rado’s high-tech ceramic is one of the brand’s most coveted materials, promising scratch resistance, lightweight wear and hypoallergenic properties. The case of this Rado DiaMaster Power Reserve watch does just that with a 43 millimetre profile inclusive of a slender unadorned two-step, straight lugs and a knurled crown at 3 o’clock. Fortified within the case is the Rado Calibre C07, a Swiss made automatic winding movement with a power reserve of 80 hours and date complication. Its intricate construction is put on display through the sapphire crystal case back where the Cotes de Geneve oscillating rotor spins with every movement of the wrist. Securing the Rado DiaMaster Power Reserve watch to said wrist is a sophisticated black alligator leather strap and a classic steel folding buckle.
