"Bart and Tim Grönefeld credit their passion for horology to their grandfather, Gerhard “Johan” Grönefeld. He was born in 1896 in Oldenzaal, a small town in the eastern part of the Netherlands, close to the border with Germany from whence the Grönefeld family originally settled. He received his horological education from his uncle, and entered the watchmaking profession in 1912.

Johan set up his watch workshop and jewelry boutique on Steenstraat, near the historic Saint Plechelmus basilica. Not only would his business there thrive, but he would also be placed in charge of maintaining the clock within the famous church’s tower."

Looks like these gentlemen have God given talent, honed to perfection with hard work and passion.

Every watch shown is to do for. Damn!
