Montblanc's Nicolas Rieussec chronograph collection uses discs as opposed to hands to indicate time, elapsed seconds and minutes and a second time zone. And, with 2013's Rising Hours, two discs on top of the other indicate the hours and whether they are day or night.
Like all Nicolas Rieussec models, this watch has an off-centre dial for the ordinary time of day with an aperture at 12 o'clock in which a disc bearing Arabic numerals for the 12 hours turns below a little triangular index. Nothing revolutionary, however, with the Rising Hours, the hour numerals change colour from black to pale blue to indicate day and night hours respectively.
The new manufacture calibre is housed inside a classically round, 43mm case made of steel or red gold. A 28-piece platinum edition is also available.
