Drawing inspiration from scientific methods, the process and visual language of laboratories and laboratory glassware has been adopted to create the ‘2.4ml’ watch. Sachs applies the handcrafted process of “ambering” (amber staining), a completely new technique in watchmaking, to the glass surface of the watch to replicate the visual language of ‘graduation’ marks typically found on laboratory measuring instruments. This process is carried out by hand and involves applying the artwork directly onto the glass surface, dipping it into the amber stain tank and baking it in a high-temperature industrial oven. This leaves the watch with the numerals, graduated minutes, hour indices and logos directly cauterized onto the scratch resistant glass surface. This technical, yet handcrafted process, results in slight variations in finish and colour, making each piece unique.
The name ‘2.4ml’ is in direct reference to the volume of air contained between the glass surface of the watch and its dial.
To date, Rolf Sachs has worked with Fortis on four art edition watch projects: IQ, frisson, 2π and 2.4ml, joining a distinguished group of designers who have created limited edition watches for the Swiss watchmaker.
