Limited Edition of 50 copies


The SUBDELTA Quattro is a unique-looking monochrome toolwatch with only one hand and packed with lots of top-of-the-line components. The Swiss Sellita handwound movement is adjusted in the Netherlands by our trusted watchmaker.

With 40mm diameter without crown, a mere 9.6mm thin and only 48.5mm long, it has the ideal proportions for male and female enthusiasts alike.

Its revolving, lumed seconds cap is very uncommon. Since the dial has no north or south, you can wear the Quattro in 4 ways (hence the name “Quattro”, which is “four” in Italian). You decide on what side the crown is. Away with obsolete markings: everything for ultimate legibility.

Being flat black and matte all over, this “Einzeiger” has military qualities. The Swiss Super-LumiNova C3 in the new X1 quality (+60% performance) in the Grade A finish is just awesome and will light up like a torch. Don’t forget to cover your wrist as you engage in combat though 😉

The 1st 25 copies of the SUBDELTA Quattro are sold and planned for shipping late Q2 / early Q3 2019. The 2nd and last 25 copies ever can only be pre-orderded and pre-paid. Delivery time is a few weeks (exclusive of summer holidays).
