Limited Edition of only 50 copies (50% sold)


The SUBDELTA Quattro is a unique monochrome toolwatch with only one hand, just like the first clocks of yesteryear. It’s packed with top-of-the-line components, such as the proven and hand-modified Swiss Sellita handwound SW210-1, Swiss Super-LumiNova C3 X1 and a sapphire chrystal.

With 40mm diameter without crown, a mere 10mm thin and only 48.5mm long, it has the ideal proportions for male and female enthusiasts alike.

Its revolving, lumed seconds cap is quite uncommon and will start many conversations indeed. Since the dial has no logo and text and therefore has no north and south, you can wear the Quattro in 4 ways (hence the name “Quattro”, which is “four” in Italian obviously).

Being flat black and matte all over, this “Einzeiger” has military qualities. The Swiss Super-LumiNova C3 in the new X1 quality (+60% performance and the strongest in their line-up) in the Grade A finish will light up like a torch.

The 1st 25 of 25 copies of the SUBDELTA Quattro are sold to eager customers. The 2nd and last 25 copies ever can be ordered now. The production and delivery time is about 3 months.
