Joining his fellow Finnish watchmakers Stepan Sarpaneva and Kari Voutilainen, Antti Rönkkö has set up shop and is releasing his first watch, the Steel Labyrinth. Details below:
"I wanted to create watch with no compromises and with my own movement, using the best materials and a very unique design"
RÖNKKÖ STEEL LABYRINTH is a hand made stainless steel watch with my own designed movement, it takes hundreds of hours to complete one watch. Designing and producing my first commercial watch has been a very long journey. It has taken several years from the idea to the final product. The reason for that is my desire to make almost everything myself. I have made sketches, 3D CAD parts/assemblies, tool paths with CAM, machining parts with CNC, finishing/adjusting movement etc. Control of the process gives me complete Design freedom.
