How Does A Minute Repeater Work?

The Minute Repeater complication (such as the one in the Jean Dunand Grande Complication we featured last week) is widely considered to be the most complex and challenging of all complications, presenting a true test of skill for master watchmakers seeking to reach the pinnacle of their craft. But just why is that? What is it about the Minute Repeater complication that makes it so…well, complicated?
Well, who better to answer that question than two master watch-makers themselves?
Brothers Tim and Bart Grönefeld cemented their reputations as master watchmakers with the introduction of the Grönefeld GTM-06 Tourbillon Minute Repeater (pictured above in platinum), the most complicated wristwatch ever created in the Netherlands. Four years in the making the piece features a tourbillon movement as well as a minute repeater complication.
As such, they are more than qualified to explain the detailed intricacies of this most technical of complications and fortunately for us (and you) they have been thoughtful enough to do so. In a detailed article posted to their Facebook page, complete with illustrations, you will learn exactly how a minute repeater works using snails, racks, levers and cams.
The article is comprehensive without being overpowering and is most certainly deserving of five minutes of your precious time. So, if you would like to expand your knowledge of Haute Horology then simply click here and read on.
