SUBDELTA was founded on a passion to construct exceptional tool watches – authentic, durable and of excellent quality.
SUBDELTA’s goal is to build watches that are so technically perfect that they can count themselves among the best in the world.
SUBDELTA watches are regulated in 5 positions with the aim of ensuring a maximum deviation of -5 / + 5 seconds / 24H.
It all started with the P1lot One. This Grade 5 titanium „Lefty“ pilot’s watch with a manual winding ETA / Unitas 6498-1 was at that time exclusively designed and manufactured for the members of the largest Dutch watch forum Horlogeforum.nl.
The SUBDELTA Periscope was the brand’s first 24-hour single-hand automatic watch, forged from bead-blasted Grade 5 titanium and equipped with a special movement by Petrodvoreds of Russia. The matte fittings and day/night dial perfectly match the submarine theme of this exceptional design.
In 2017, the „Ace“ joined the SUBDELTA collection, a robust 42mm pilot’s watch made of Grade 5 titanium and a sandwich dial that offers maximum readability day and night. The heavily modified and revised Swiss Made hand-wound movement (Ref. ETA 6497) with swan-neck regulator was the perfect choice here.
The limited edition SUBDELTA Quattro was released in 2019. This 40mm watch with a Swiss-made mechanical movement has a unique seconds dial among other fine details and special features. This single-hand watch was hand-modified by a master watchmaker and can be worn with the crown on either side and thus on either wrist. The dial has no defined 12 and 6 o’clock positions, so the watch can be rotated.
