The SUBDELTA story

Subdelta Pilot one

Each year, Holland's largest watch forum (Horlogeforum.nl) launches a Limited Edition. Members can pre-order a modified, existing watch for a few hundred dollars. Usually, an average of 25 watches was being sold. In 2014, however, a few true watch aficionados talked about doing something that has never been done before: to design and build a watch of their own.

Projectteam P1lot One

They met in a pizzeria in the city of Utrecht and shared their ideas on what is becoming the perfect pilot's watch - awesome specs, yet still affordable. "P1lot One", a hand-wounded titanium "lefty" pilot's watch built for a group of really passionate watch enthusiasts. It was built by hand out of grade 5 titanium. In the Netherlands.

Hans de Ree got together again for the next project - and that's when SUBDELTA Toolwatches was born. Time to go pro!

The first SUBDELTA watch

Subdelta Periscope Singlehand Watch

SUBDELTA What the 2016 Periscope, a one-hand 24-hour automatic piece, forged from bead-blasted grade 5 titanium and housing a bespoke movement from Russia. The matte hardware and day / night dial totally fitted in the submarine theme. It was built around 25 enthusiasts around the globe, referred to as "Commanders". They all have their own personal number, which is engraved in the crown. This teutonic design is something completely off the beaten tracks and watch enthusiasts all over the globe are waiting for a second hand specimen. They rarely come though though.

Being now built under SUBDELTA, nothing has changed from the spirit and quality of the "P1lot One", as it has come to be known At option, neither making a big profit a consideration.

Ace and Blue Ace

Subdelta Ace

The 2017 project is called the "Ace", a rugged, 42mm, purpose-built tool-made out of grade 5 titanium and a single dial providing maximum legibility day and night. The Swiss hand-wound and re-engineered pocket-watch movement (ref. 6497) with swan necks is a sturdy sapphire crystal case back.

The prototype of this is a world tour, where it is with future owners in the United States, Singapore, Hong Kong and Switzerland. The 2017 model is sold out completely. The latest edition of this remarkable watch 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.

What's SUBDELTA up to?

SUBDELTA continues to redefine all the rules that make a brand, in an attempt to build that perfect timepiece, true to its origins. Next up will be the SUBDELTA Quattro (runner-up 2019 Limited Edition Dutch Watch Forum). 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. Delivery Q4 2019.

Subdelta Quattro

For 2020, we aim to produce two new models. Their prototypes are being developed at the moment. As soon as we're confident to show you the sketches and specs - we will.
