batch 1/2: limited to 25 copies


The SUBDELTA Quattro is a badass toolwatch with just one hand. At only 40mm in diameter and a mere 9.6mm thin, it has the ideal proportions.

Its revolving seconds cap is unique and has a lumed logo. Since the dial has no north or south, you can wear it in 4 ways (hence the name “Quattro”, which is “four” in Italian) with the crown on the left and right side on each wrist.

The SUBDELTA Quattro was runner-up at the 2019 Limited Edition election and lost by a mere 4 votes (57 vs. 61). By popular demand, the SUBDELTA Quattro will be launched all the same.
