OW watches are designed at the headquarters of Ollech & Wajs Precision A.G., on Bellerivestrasse in Zurich. Each timepiece is individually assembled and adjusted in Haute-Sorne, in the Swiss Jura, following the high standards of precision and quality which have made it a famous seat of Swiss watchmaking
This long process always begins with rigorous specifications, directly inspired by Ollech & Wajs’
Vietnam era production which was prized for being robust, readable and water-resistant.
Each new model is the result of an 18-month designing process, more than 30 sketches and dozens of detailed technical blueprints with zero margin for error.
One after the other, 8 prototypes undergo a series of tests to detect the slightest flaw in their casing: water-resistance up to 200M, 400M, 1000M and finally 1200M, resistance to impact, scratches, disassembly and successive reassembly.
At the same time, 5 renowned movements have been rigorously tested to determine their accuracy in 5 positions, their regularity and their ease of maintenance. Like Albert Wajs 50 years ago, our final choice was the Ébauches S.A. factory and its ETA 2824/2, for its indisputable reliability.
Each movement is taken apart, allowing the engraving of the OW brand on the plate and the addition of a new and exclusive rotor, fashioned after OW’s logo.
The manufacturing process of your watch begins in the Swiss Jura and involves more than a dozen operations before the final cleaning. The desired shapes are first cut and stamped, then properly machined and eventually given a brushed-satin finish.
After a thorough inspection, the dial is affixed to the movement on the assembly bench. Installing the hands one by one requires the highest level of dexterity and concentration, as does each step to complete the encasing of the watch.
Your OW will now go through a multi-step process to ensure that it is perfectly finished. The precision and regularity of movement are tested in 3 to 5 positions, the standard among major watch brands. A passage through a specially pressurized box allows to check its water-resistance up to a depth of 3,280 feet. Then it is time for the final test: a meticulous visual inspection hunting down the slightest speck of dust.
OW watches are guaranteed for 3 years against any manufacturing defect.
Great Britain: NATO bracelets.
Rest of the world: dials, hands, packaging.
Each of our partners and subcontractors is selected for their technical excellence, without overlooking a key-component: the true passion of watchmaking. In our workshops in the Jura, each watch is assembled by hand with love and care. This is how we guarantee the “Swiss Made” quality of our products, upholding the highest values of the Swiss watchmaking tradition.
OW’s watch straps are made from the finest leathers, selected, cut and hand-sewn by a renowned Italian tannery.
You can also choose from our large choice of exclusive NATO straps, assembled and sewn in Wales, by the official supplier of her Majesty’s armed forces.
Stainless steel and reinforced rubber straps will soon be available as well, alongside a new collection of travel accessories.
