Subdelta Ace

SUBDELTA Ace - A Watch Representing Subdelta's Take On Future Pilot's Watches. Bold, beautiful & badass - all in one watch.

While it is conceived as a wristwatch for pilots with maximum legibility in air and space, the Ace also pays tribute to historic elements. Numbered Flieger-crown, a classic Handmade Leather strap with rivets and modified hand-wound movement with central hacking second.

The more futuristic elements are to be found in the contemporary font on the dial, the unusual dots as indices rather than the more typical stripes, the lit inner circle with invisible crosshair and the both futuristic and classic hands. The generous use of Swiss Super-LumiNova BGW9 "grade A", which is off-white in daylight hours and bright blue at night, further enhances the modern look at night and makes it very clear to read any circumstances.

The Ace is a sturdy 42mm watch, entirely hand-made and milled from extremely light and strong grade 5 titanium and housing the best components available - many of which can be found in some of the most iconic pilot watches from other established and well- known brands. Further, the Ace wants to use a re-engineered movement with an expensive and complex central seconds hand modification.
