I guess we where really lucky to have the presentation of a complete new watch brand as our first day of the European GTG. The Grönefeld tourbillon minute repeater is a beauty to see in real life. Personally i just love the lugs, IMHO a modern and rugged version of the classic teardrop lugs.
And the cathedral gongs sound totally incredible... i never thought a wrist watch would make such a loud, clear and warm sound. Impressive!
