1981 - 94

OW survives the quartz crisis by scaling back.

Despite the demand for quartz and intense competition from Asian manufacturers, Albert Wajs  steadfastly refuses to manufacture anything other than mechanical watches. (To this day, Ollech &  Wajs is one of the few Swiss brands that has never adopted a quartz movement.) Convinced that  Swiss-quality mechanical watches still have a future, OW reduces but never ceases production,  continuing to serve its professional and military customers around the world.


A new generation of watches.

With the renewed interest in mechanical watches that Albert Wajs predicted over a decade earlier,  Ollech & Wajs reboots its production, reigniting the OW brand with a new generation of sports  watches, military watches and chronographs.


A.I Wajs and the M-Series.

After Joseph Ollech passes away, Albert Wajs creates a new company and introduces a line of  OW watches to honour his business partner and friend. The M-Series, including the Mirage chronographs, reaffirms OW as shorthand for rugged yet affordable, professional-quality  timepieces.


A new direction for OW.

After 60 years at the helm, advancing in age and with failing eyesight, Albert Wajs decides it is  time to hand the company on. OW’s former distributor for the French market, a long-term  collector, takes over. Over the previous five years, OW has developed an exceptional new range  of timepieces, equal to any challenge and exemplifying the original vision of Joseph Ollech and  Alberts Wajs.
