Under the loupe today is a very nice vintage Ollech & Wajs 2002 Valjoux 7730. O&W was created in Switzerland in the late 1950’s, and grew in popularity in the 1960’s, especially with servicemen, sportsman, divers and aviators thanks to a strong reputation for quality and dependable mechanical watches. O&W still operate today, see their website
Following on from this post, Anthony sent me another watch for a service. Once again it is a watch with military influence: a very nice Ollech & Wajs Chronograph. O & W is a Swiss watch company created in 1956, which specialises in automatic and manual-wind mechanical military and dive watches.
