The Subdelta History

SUBDELTA is founded from the passion to design and build exceptional tool watches which are very authentic, durable and with outstanding quality.

Our mission to build the best, toughest and highest quality Tool Watches in the world

It all started with the P1lot One. This stunning grade 5 titanium "lefty" pilot's watch with a manual-wound ETA / Unitas 6498-1 was made exclusively by and for members of Horlogeforum.nl, the largest Dutch watch forum.

Subdelta Periscope, a one-hand 24-hour automatic piece, forged from bead-blasted grade 5 titanium and housing a bespoke movement from Petrodvoreds from Russia.

The matte hardware and day / night dial totally fitted in the submarine theme. This teutonic design is something completely off the beaten tracks.

The 2017 project is called the "Ace", a rugged, 42mm, purpose-built tool-watch made out of grade 5 titanium and a sandwich dial providing maximum legibility day and night.

The heavily modified and re-enginered Swiss Made hand-wound movement (ref. ETA 6497) with swan neck regulators.

The limited edition of 2017 , the SUBDELTA Ace is a blue-faced, steel version of the Ace, called Blue Ace. : some with a polished crown and some with a beadblasted crown, both in titanium.

Our 2019 limited edition is the SUBDELTA Quattro . This 40mm toolwatch with a Swiss mechanical heart has a unique revolving seconds cap, among other fine details and specs. This one-pointer is modified by hand by our Dutch Watchmaker and can be worn with the crown on either side and thus on either wrist. The name "quattro". This can be achieved by swapping the strap halves: the dial has no north or south, so the watch can be turned around.
