Ollech & Wajs is a Swiss watch brand co-founded by Albert Wajs and Joseph Ollech in 1956. The brand creates rugged, precise mechanical tool wristwatches well-suited for military, aviation, diving and sports.
The robust stainless steel case of each Ollech & Wajs is stamped, machined and satin brushed in the Swiss Jura by expert hands. Joseph Ollech and Albert Wajs chose early on to use specially commissioned fine mechanical movements from ETA and Valjoux. This tradition lives on through the newly modified ETA 2824 movements.
After an initial quality control to ensure its accuracy, it is meticulously taken apart and its main plate is engraved with the OW logo. Ollech & Wajs also adds a new and exclusive rotor, machined and decorated in the Swiss Jura. Each movement is then carefully adjusted to 3 or 5 positions, twice, to meet the standards of finest Swiss watchmaking. The watches are also fitted with screw-on crown and case-back to guarantee exceptional water-resistance.
Most Ollech & Wajs watch self-winding movements can be wound properly by most watch winder boxes. Usually Ollech & Wajs’s self-winding movements need to rotate 650 - 800 revolutions per day, and most of them can be wound clockwise. So please take some time and like to choose a cute clockwork that suits you and your watch.

If you could not find your watch model (or caliber) in this table, you may determine your Ollech & Wajs. winding mode on a trial basis. You should select the combined winding mode (CW+CCW) and the minimal number of turns per day (TPD). Then place your watch into the watch winder and check after a few days how accurate your watch shows the time. If it runs behind, it is necessary to increase the number of TPD by one step.
