The White Gold and or Stainless Steel version of the ‘Grand Master’ Complication is our pinnacle thus far. A design to rival the very best in the industry but at a fraction of the cost, the KGS GMC will be one invitation worth getting.

The ever growing affinity with white gold and platinum are only echoed more by a highly polished steel in the modern world of horology. The former are obviously limited to deeper pockets but what many don’t know is that Rhodium, a rare metal that is resistant to corrosion can be used to combine with yellow gold thus turning it ‘white’ as in white gold. This is something we are taking very seriously with our silver version of the Grand Master Complication. (Silver simply a term given as a descriptive.)

 ’Tranquillity’We’re all familiar with the warmth that yellow and rose gold offers, but to us it simply would have been wrong to ignore the white or silver version. It was whilst thinking of implementing this into our designs during a trip to a place of thought, that the idea of creating a silver / white version of our Apex masterpiece the wording ‘Tranquillity’ came to mind.

If truth we’re told, gold in its standard colours is considered ostentatious— a blatant show of wealth. Whilst this isn’t a bad thing, we thought the combination of a highly sophisticated timepiece in an, on the face of it innocuous casing, would be rather fitting, so after some market research with our growing audience we found this to be a worthy thought. We thus look forward to the Silver Grand Master adorning those who appreciate our way of thinking.

The current unprecedented climate caused by COVID-19 means it would be remiss of us putting an exact cost on this. However, we are certain that we will make this the most affordable high end multiple complication timepiece on the market on a cost per quality aspect.We achieve this by refusing to make the supply chain any longer than it need be. By selling directly to the consumer without huge advertising costs to recover. The bottom line is we believe word of mouth will be enough of an advertisement.
