We are passionate about our trade. We seamlessly complement each other. We work surprisingly well together to craft the most beautiful watches in the world.
In our way, we are setting forth a family tradition that began back in 1912. We studied with the best watchmakers in Europe and returned home to bundle our strengths. It is a great privilege to share our passion in life.
Bartholomeus Albertus Johannes Grönefeld, ‘Bart’, was born in 1969. After concluding his studies at technical school in Oldenzaal, Bart travelled to Rotterdam and attended a school for watch technicians. Later, he travelled to Switzerland and trained at the world-renowned watchmaking school Wostep, Neuchâtel. After leaving Wostep, the bright lights of London beckoned and Bart worked for Asprey, the prestigious jewellers. One year later, he returned to Wostep, keen to advance his understanding of complicated watches.
Each day he would work with a talented group of artisans on minute repeaters, chronographs and grande-sonneries. Later, his younger brother, Tim, joined him in Switzerland at Renaud et Papi.
Tim Lambertus Joseph Grönefeld, simply ‘Tim’ to his friends, was born on the 12th March 1972. His career path took a similar route to his older brother’s. After leaving the same technical school as Bart in Oldenzaal, he attended Vakschool in Schoonhoven, a further education establishment for training watch technicians.Tim, chose to follow his older brother and also travelled to Switzerland.
It did not take long for Tim to show his watchmaking prowess. He soon assumed responsibility for the training of other watchmakers. Moreover, he was also placed in charge of the assembly of tourbillons and regulator escapements, playing a key role in the quality control of complicated movements.
