Fabrication

Our watches are made of the finest Materials available using 30 years of Aerospace and design experience.
The case, back cover, bezel and band segments are made from a high grade 316L surgical stainless steel. The snap-on band headers internal components are made from 17-4PH hardened aerospace stainless for a long service life. The watch case post are titanium nitride coated for ultimate wear and durability. The watch dial face is machine cut from 6061-T6 solid bar stock aluminum, then anodized for a superior lifetime finish. Band segments use screw pins, not pressed in pins for easy service and reliability.

Final inspection and overal quality control is directed by Robert Koelewyn himself to ensure 100% customer satisfaction and to ensure all watches have the standard he intended as designed. Then the watch is serialized and stored in their custom designed box from where they can be shipped anywhere in the world.
