Subdelta Ace Lumeshot

SUBDELTA Proudly Introduces Its 2nd Commercial Model, The Titanium Ace - A Watch Representing The Firm's Take On Future Pilot's Watches. Bold, beautiful & badass - all in one watch. Orders are closed.

Subdelta Ace

While it is conceived as a wristwatch for future pilots with maximum legibility in air and space, the Ace also means tribute to historic elements. Flieger-crown, a classic leather strap with rivets and updated hand-wound movement with central hacking second for example.

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.

Subdelta Ace modified movement

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. The movement is now 4 times more expensive than the standard one with small seconds hand.

Technical details

Upgraded hand-wound movement: The Ace is equipped with a re-engineered Swiss Made UNITAS 6497 displaying a large central second hand with hacking feature (stop-seconds). The bridges have côtes de genève finishing on the baseplate. In addition to blued screws and a beautiful swan neck, this original pocket-watch movement sports a unique modification: a signature crooked bridge used to centralize the second hand. The movement wants to be hand-adjusted to 6 positions, 1 more than factory settings. A printout wants to prove this. SUBDELTA's unwavering commitment to remain true to its values. SUBDELTA ACE

Case material and construction: All parts of the Ace's case are hand-crafted from grade 5 titanium, being the highest grade of this exquisite material due to its lightness and hardness. All titanium used at SUBDELTA is milled, finished and decorated in the Netherlands.

The combination of hand-polished bevels on all lugs the industrial-looking bead-blasted case is a statement in itself of what's being housed inside. The SUBDELTA case has the firm's DNA etched in bold yet simple lines, its distinctive shape being an evolution of the P1lot One and Periscope case with additional refinement. Dimensions are about 42 x 54 x 13 mm (width x length x height), 22 mm lug width.SUBDELTA-ACE Pre-Flight Briefing 16-05

Straps: The handmade olive leather straps by Dutch artisan are attached to the case using solid stainless steel spring bars. There are many additional options available to make the ACE your own even further. Finally, there's a secret military-grade NATO or ZULU style strap as well. This will be unveiled during the unboxing by the new owners.

Drilled lugholes: The case has been drilled with a very high degree of accuracy on an extremely hard material. Bergeon is included to make the straps at home easily. SUBDELTA-ACE-Pre-Flight-Briefing-15-13

Crystal caseback: The matching grade 5 titanium screw down caseback is rated waterproof for 60 meters (6 ATM) when shut with strategically positioned rubber gaskets. The double-domed sapphire crystal has thus been anti-glare treated on the inside, so the nicely decorated movement can be enjoyed with minimized reflections. The watch is individually numbered and details are laser etched into case and case back.

Personalization: Each SUBDELTA has a meaningful date engraved between the lower lugs (ie up to 6 numbers) as a free option. By default, the space between the upper lugs is laser-engraved with Ace of Spades as a reference to the name of the watch. The unique build number is laser-engraved on the outside of the crown as a constant reminder of the unique quality of the particular timepiece.

The crown: The bespoke 10mm titanium classic "Aviator" crown has been sourced from the best Swiss crown maker and is placed on the left side of the case for maximum comfort and freedom of wrist movement. SUBDELTA-ACE Pre-Flight Briefing -16-06

Bespoke tang buckle: The handmade tang buckle is also made out of bead-blasted grade 5 titanium.
