The opportunity arose for Kari Voutilainen to work with a batch of Longines 360 calibres. These are observatory movements with an unusual rectangular layout.
Each one has been completely reworked. Numerous new parts were made and adapted, before being hand-finished to the highest possible level of visual and technical perfection. Each watch was then ready to be hand-guilloché in the unmistakable style that is a hallmark of the Voutilainen workshop.
