1960’s NOS OLLECH & WAJS Swiss Selectron Sliderule Military Aviator – FHF Cal. 96-4


Out of stock

A rarely seen 1960’s Vietnam-Era new old stock model that has been fully service in-house here at our Localtime Spa. Ollech & Wajs [Swiss] is one of those cult brands that trully carries the full weight of their name. Their products were wonderfully designed and no expense was spared in using the best materials and movements available. This trully classic Selectron Sliderule aviator watch, is one of few and different Vintage O&W models we have discovered [the rest are listed separately in our store] and is in a New Old Stock vintage and original condition both visually and mechanically, with the FHF Cal. 96-4 really taking centre stage and stealing the show! We have included many photos of the watch, including some extreme macro shots we made just for fun. The watch is wearing a great quality handmade calf leather strap and Localtime buckle [more information and variations of these buckles can be found in our eBay store under eBay item number 400485469612] that we think fits the watch extremely well. As with all our in-house watches this will also come to you with a 6-month written warrantee from the date of purchase. Please contact us for whatever questions you might have.

Sliderules were useful on watches for pilots that could use them for a variety of much-needed information that the era’s technology did not offer, like rate of ascent/descent, average fuel consumption, ETA to destination based on speed, etc.
