Inspired by the designers desire for the finer things in life, the KG&S ‘Grand Master’ mirror images many aspects of his taste in surroundings often seen in his families’ home. From the luxurious yet age defying brown leather furnishings that offer warmth and comfort, to the intricate thought processes behind the design, the Grand Master is a demonstration of what might be called classically complicated, something that offers that gentleman’s feel. The gentleman in this case will know who he is.

Absolutely. We have no interest in creating an unlimited edition of any of our models, not least we don’t possess the ability to do so. A set Limite of just 50 -150 are planned.  
At this present time the Grand Master Complication is by invitation only. This may change with time, however, we firmly believe that our brand must adhere to its ethos of being the brand of Legacy. You can read more about that throughout the site. 
The current plan is to create a custom in-house movement. However this will still be created around the ETA Valjoux 7751 Top Execution.

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.
