The Design

Inspired by Aviation Cockpit Instruments

Drawing inspiration from cockpit instruments designs and the magic of flight, the OPUS line of watches by ALCADUS make a bold statement about who you are as a person, what you value, and the kind of life that you are living. Featuring a sapphire crystal lens, a venerable Swiss ETA 2824-2 automatic movement, and Swiss Super-LumiNova® luminescent hands, dial, and watch crown, these watches are durable, resistance up to 10 ATM and 100m water submersion. You can change out the strap easily because of the drilled lug holes, and sized at 39mm, the design is versatile, suited to a wide range of occasions and settings.

Reduced to its simplest components – the true bare essentials – the luminosity of the Swiss Super-LumiNova feature makes this a watch that you can take with you everywhere you go, relying on it and depending on it completely – with your life if necessary.

In a traditional Flieger watch, the triangular index at 12 O’clock position enables the pilot to quickly determine the upward orientation of the watch in the dark. Substituting the traditional triangular index with the ALCADUS logo, the OPUS 39 puts a new spin on this design. In addition, there is another subtle ALCADUS logo in the seconds hands, and calling back to the watch crown designed for pilots wearing thick gloves and flight suit, the OPUS 39 features a similar watch crown.

Molded from marine grade 316L stainless steel, the 39mm OPUS is coated with a high tech scratch-resistant coating with a hardness of 800 HV (four times the average 200 HV of uncoated stainless steel), so you can wear this watch for years on end.

Screw-down Crown

The OPUS 39 is water resistant up to 100m / 333ft / 10 ATM, much greater than the 30m water resistance rating common to most pilot watches.

Inspired by the Brave Voyages of Yesteryear

A true piece of vintage art, the OPUS 39 features a box-shaped crystal that sticks out beyond the case edge/bezel, an improvement on the easily-scratched plexiglass (acrylic glass) previously common to box-shaped watches lenses.

Sapphire Crystal – Just Try to Break It

Extraordinarily hard, the sapphire crystal used in the OPUS 39 is virtually unbreakable, rivaled only by the diamond in terms of hardness and scratch resistance.

More Affordable than Ever

Normally, box-shaped crystal is found only in watches that cost upwards of $2,000-3,000, but when you reserve the OPUS 39 through this campaign, you are getting it at a fraction of the price.

Anti-Reflective the Smart Way

There are five layers of anti-reflective coating applied to the top lens to prevent glare – not on both sides, as that can lead to scratching. Instead, the OPUS 39 features an inner anti-reflective coating.

Swiss ETA 2824-2 Movement

World-famous for consistency and reliability, this is a Swiss movement that has gone down in the annals of history as a notable feat of engineering. To us, there was just no other option when we were designing the OPUS 39.

The first batch of pre-orders will be assembled with an ETA 2824-2 elaboré with customized skeletonized rotor with engraved with ALCADUS logo.
