He has used his multidisciplinary approach to create the ‘2.4ml’ watch as his fourth collaboration with Fortis watches. The stunning timepiece takes its name from the volume of air contained between the glass surface of the watch and its dial and will be presented at baselworld 2017.

Rolf Sach has embraced the aesthetic of laboratories and all of the visual design present within them, he brings it all together perfect and combined in a way that only Rolf Sach can this beautiful  ‘2.4ml’ watch was born. To create the dial markers ‘ambering’ (amber staining) was applied to the glass so as to replicate the visual language of ‘graduation’ marks which are often found on measuring instruments. This process required an accurate eye as it was carried out by hand and involved applying the artwork directly onto the glass surface, dipping it into the amber stain tank and then baking it in a high-temperature industrial oven.

sachs explains ‘I always look to experiment and go beyond the expected. for this fortis artist edition, I was inspired by the visuals and techniques found in chemistry laboratories and adapted the scientific process of ‘ambering’ to create a new way of crafting a time piece, printing onto the glass surface instead of the dial.’
