The Desk Diver is made from a recovered 1970's Swiss made case. We created a new dial and handset for this watch to match the 70's look. The watch has been fitted with a Sellita SW210 manual wind movement and brand new Acrylic crystal matching the shape of the original. The watch has no water resistance but is guaranteed to be a Superlative Desk Diver - Unofficially Certified! The dial and handset has X1 Superluminova so you can easily see the time in a dark office environment! Note that this is made from a new old stock vintage case. It was never used prior, however over the years of handling them they do each have unique patina. You may find small marks on the case. We selected the best available for sale. We can make only 75 total of these fantastically fun watches! What Swiss Brand Made the case? The inside of the caseback is marked "Aetos SA - Swiss Made." We could not find much out about this brand in our research, apparently this brand was a Swiss case supplier, thats all we know. We did have fun imagining what the dial and hands might look like, since we had no reference of what it did originally. We recovered these cases from a defunct watch parts supplier who had a gross of new old stock watch parts.
