Haldor Technology

HHC (Haldor hard coating)

Is a special hardening process to increase the scratchs resistance and hardness of the steel. It can be applied also on Titanium. This process creates a hardened barrier about 25microns deep on the upper layer of the metal, so the upper layer of the metal becomes much harder. We can reach about 2000HV (vickers) for the stainless steel (that's 7 times harder than the normal stainless steel!). The hardening process is applied before the steel cools, creating a protective layer of the steel. Using this technology the surface of the watch becomes significantly more resistant to scratches.

DLC (diamond-like carbon coating)

Is a nanocomposite coating that has unique properties of natural diamond low friction, high hardness, and high corrosion resistance. DLC coatings can have different structures and properties that rely on the ratio of diamond and carbon or other fillers like hydrogen, silicon, and metal in the layer. After the DLC process the metal changes the color to black. The hardness of a steel is about 1000-1200HV. Haldor can also apply this technology over HHC to obtain an ultra hard metal. In this case the steel can reach about 3500HV.

Magnetic Field Protection

To protect the watches against magnetic fields we add a light metal cage inside the watch case with some other modifications. The watch movement is protected up to 80.000 ampere per meter (A/m).

Top grade accuracy

We use only Swiss Made automatic movements produced by ETA SA Manufacture Horlogère Suisse. Before assembling we test and set the mechanical movements with the latest Witschi Eletronics equipment. Haldor watches are equipped with following mechanical movements: ETA 2824-2, ETA 2892A2, ETA 7750. All our movements are adjusted to Top grade level. The accuracy is almost like a Chronometer, but in this case we must consider strict standards prescribed by the COSC.

Metal by Haldor

Sapphire crystal

All our watches are fitted with sapphire crystal. It is made of crystal powder heated to a temperature over 2000C. We cut it with great precision from a polished slice of solid sapphire. After that the sapphire is polished for hours to produce the desired finish. Next to diamond it is the the hardest transparent material known on earth. It so hard that only a diamond can scratch it.
