A rarely seen 1960’s Vietnam-Era ‘Computer’ model that has been professionally inspected in-house at Localtime.

Ollech & Wajs (Swiss) is one of those cult brands that truly 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. 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. This rare Computer 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 nice vintage and original condition. The watch is wearing one of my own canvas sailcloth straps in black with grey stitching, that I think fits the watch extremely well. These straps can be purchased separately from my eBay store: 401623826555. You can also see more information in the last photo here. I have included many photos of the watch, including some extreme macro shots I made just for fun.

As with all the watches I handle in-house, the BIN price includes a 6-month written warrantee from the date of purchase. Please contact me for whatever questions you might have.

Extra: Try my Localtime canvas sailcoth straps! I have found them to be of a very good value and a great match especially for sport watches or chronograph watches that will combine well with this style of straps. Their colour is black and they come in 4 sizes [18-20-22-24mm] and 7 colours of contrast stitching. Their length is approximately 100mm on the buckle end [including the steel buckle] and 120mm on the tail end; so not short but not too long either. They are nicely padded, measuring 5mm thick at the lug end and they taper down to 3.50mm at the tail end. They have two keepers, one of them is fixed and the other one is floating. I have included many photos when you scroll down, so you can get a better idea of what you are ordering. A good quality pair of spring bars is included with each strap. Feel free to contact me for whatever questions you might have.

Important Note On Condition: Sometimes I am asked what I exactly mean with ‘professionally inspected by Localtime’. Here is my theory on vintage watches: as a purveyor of vintage watches, my effort is to always do only what is needed to the watch. I do not buy ‘junk’ watches to resell. I am choosy with my purchases and always sell watches that are, to my knowledge, authentic and in good condition. I first inspect the watch, both visually (cosmetically) and then mechanically. If I judge that the watch is not yet in need of a full service then I do not put the watch through a service which, by the way, entails a lot of risks too. Instead, I give it what I call my ‘Spa’ treatment which will include a cleaning, changing of gaskets, oiling, lubricating and mechanical testing. If the plexi is heavily scratched or discoloured and it can not be cleaned, I change it. If the crown is wrong or worn, I also change it. Now, if the watch is in need of a full service, then my ‘professionally inspected’ description becomes ‘professionally serviced’. In both cases, I include a written warrantee with my buy it now price and I always describe what I have changed, if anything, on the watch.

Important Note On Straps/Bracelets: The straps I use on my watches [leather, canvas, suede, rubber] are always brand new, unless otherwise mentioned and, in most cases, I also sell them separately in my store, in different colours and sizes. In the case of metal bracelets, if the watch is NOS, the bracelet is also unused. If the watch is pre-owned with its original bracelet, then the bracelet is also pre-owned, unless otherwise mentioned. Either way, if in doubt, please ask.
