SUBDELTA Toolwatches

SUBDELTA makes toolwatches in low production runs for real watch enthusiasts. No middle-of-the road style copies of existing brands and models, no. A SUBDELTA has a design of its own and is always a toolwatch with a rugged military theme, made out of the finest materials and components we can possibly source.


We’ve sketched a couple of new models in a totally new range, consisting of:

  • Air (airforce style flieger watches)
  • Water (navy style diving watches)
  • Ground (infantry style military watches)

Each model and variant shares the same design philosophy and specs:

  • ultimate legibility and ruggedness: hardcore toolwatches – all of them
  • R.O. Shock-System: unique, patented Dutch system, proven in space by our own astronaut Andr├ę Kuipers (we’re the 1st licensed brand)
  • 41mm diameter without crown and as flat as possible
  • hardened, beadblasted 316L with drilled lug holes and solid casebacks
  • sapphire crystals with AR coating on the underside
  • 20 bar (air and ground) or 100 bar (sea) pressure resistant
  • proven and top-notch Swiss Sellita automatic movements
  • black and blue dials, as well as “specials” such as khaki for field watches
  • “Leading Hand” principle: the most important hand sticks out from the rest
  • “Key Data” principle: low-key data has an understated color (i.e. logo)
  • Swiss Made
  • the best available quality Swiss Super-LumiNova┬«
