Watch company Rebellion has created a watch set with a combined total of more than 300 diamonds in the case and crown of the timepiece.
The invisible mounting technique was developed by Van Cleef & Arpels for setting the diamonds, according to gizmag.com. The idea was to prevent the metal setting from obscuring any part of the 307 diamonds on the case, weighing 24.05 carats and 12 diamonds in the crown with a weight of 1.02 carats.
The Rebellion Black Diamond REB-5 (left) sells for 890,000 Swiss francs ($928,500), while the Rebellion REB-5 costs 189,000 Swiss francs ($196,000).
The entire case of the Black Diamond had to be rebuilt to enable the gems to be set.
To enable the so-called invisible setting, the diamonds had to be cut with extreme precision and set using minimum tolerances, with the setters using microscopes. Each stone was selected based on its top colour and its IF to VVS clarity, then individually shaped according to its position.
It took almost 1,000 man hours to carry out the programming of the machines and tools, cutting of the diamonds, visual inspection of each part, setting, assembly and adjustment. Rebellion carries out all its design and manufacture in Switzerland.
Only 12 REB-5 watches are produced each year and can be ordered in red gold, titanium or black DLC titanium black alligator leather straps with double folding buckle.
