Dear Customer,

thank you for showing an interest in the PRIM OK-A DLC watch.

For all future contact with us, you will be assigned a personal sales specialist, whom you can contact at any time and who will assist you in choosing a suitable watch for yourself, a loved one, or an acquaintance.

Please indicate below the purpose of your interest:

OK-A is the international designation for Czechoslovak civilian aircraft. As the name of this PRIM sports watch therefore suggests, it is inspired by the aviation industry. In this spirit, a completely new case with a threaded crown was created, which is solid, but at the same time, very comfortable to wear.  The DLC finish in black not only gives the watch an impressive look, but also increases the case´s resistance to external conditions.

The OK-A inscription on the dial is visually different from different angles due to the printing technology used. Distinctive luminescent indices, readable even under difficult conditions, are reminiscent of aircraft on-board instruments.

The dominant feature on the closed caseback is the two-bladed propeller, a reference to the beginnings of Czechoslovak civil aviation. This symbol decorated the buttons of the pre-war uniforms of CSA employees. The water resistance of the watch has been increased to 10 ATM, as a result of which the PRIM OK-A model is suitable for wearing even in more demanding conditions.

The watch belongs to the PRIM Automatic model series and is equipped with a high-quality Swiss ETA movement with automatic winding. All the other components, such as the case, crown, hands and dial are made in our factory in Nové Město nad Metují by Elton hodinářská.
