The Damasko DC57 Black is made by Damasko Watches of Germany. The watch is made in-house by Damasko. Many in-house technical innovations are found in this fine timepiece alone. The unqie luminous dial is coated entirely with luminous compound Luminova™ C1. The watch is powered by the tried and tested Valjoux 7750 which is fine tuned and tested by Damasko to high precision.

The 40mm watch case is made in-house by Damasko and features the industry's toughest material yet. The material is called "ice-hardened, nickel-free stainless steel". What is so unique about this steel is that they are absolutely nickel-free, offer a good corrosion resistance, and can be tempered up to 64 HRC/800Vickers which is four times the hardness of every other steel currently used in the watch industry. And this ice-hardened steel is used for the entire case, crown and pushers. Finished with extremely abrasion-proof Damest layer and the PVD black treatment, lending a full blackout aesthetic in tandem with its utilitarian dial.
While other manufacturers choose to harden the surface of 316L (1.4435) or 1.4301 up to 1200 Vickers by diffusing carbon into the top layers of the steel, there is no way to temper the material. Due to the austenitic structure of the alloy it is impossible to make sure that that steel remains its hardness throughout the body.
Various tests have proved that this kind of surface treatment is not suitable for our purposes because it only hardens the top layer of the metal. This leads to the so-called eggshell effect. We were able to dent and scratch the “hardened” surface with an ordinary pair of tweezers (which are normally made from spring steel) because the material underneath the hard layer was not able to withstand the pressure. With the height at 13.8mm, and lug-to-lug of 48.6mm, the watch wears extremely well on most wrist!
The crown system is also another patent of Damasko. After extensive research Damasko developed a decoupling screw-down crown which is constructed according to standards derived from mechanical engineering. The use of a hex bolt with 2mm width across flats and the fact that the entire crown, including shaft, thread etc. is made from our patented hardened steel (60-62 HRC) results in a longevity which is second to none.
All gaskets of the new crown system are made of Viton™, a material with high chemical and mechanical resistance which is superior to every other gasket material (Nitril etc.) currently used in wrist watches.
Crown and pushers are also equipped with our patented lubrication cell which ensures a smooth action and lubricates the shaft and the gasket. The tubes of both crown and pushers are, according to industrial engineering, screwed into the case using a special key. Almost every other watch manufacturer makes use of an inferior press fit tube.

Yet another Patent found in this watch is the Gasket system. The new gasket system overcomes the common problem of moisture and dust ingress during the operation of the crown and pushers.
Every Damasko watch features an important technical detail which is not visible at first sight but has a major influence on its accuracy under harsh conditions – the anti-magnetic cage. Only very few mechanical pilot’s watches are equipped with this feature.
The unique inner case consists of the dial, the movement retaining ring, and a second back. These parts are made of a special material with anti-magnetic characteristics which is able to withstand magnetic fields with a strength up to 80,000 A/m. They are machined with maximum precision to ensure an exact fit and to prevent the escapement from being magnetically charged.

The Damasko DC57 Black watch comes with a 20mm black genuine leather strap with premium rubber backing for better water-resistant.
In short, if you are in the market for a chronograph and appreciate good craftsmanship, the DC57 Black is one of the few overly-built chronograph you can get. Feature packed with specifications like the scratch resistant case, the anti-magnetic properties, reliable chronograph movement with a whole lot of engineering to sum it up.
