Ok, I'm going to state my case slightly more strongly than before.
Why should we choose this watch over all the others?
The IWC Aquatimer is a simple, yet elegant design. It can use a 2824 or 2836 movement making it a cheap, reliable option. The case is unique with an inner bezel that's controlled by a crown on the outside which gives it an unusual edge that isn't too difficult to reproduce with a gen version and CNC-based system. With a simple change of material (SS to Ti) and dial, it becomes the Aquatimer 2000, a more striking yellow-hinted design. Additionally, the bracelet is already available on the IWC GST models, meaning we know it can be reproduced without worry. With the choice of rubber or steel, this watch can go from wet suit to Armani suit with a simple strap change.
With one not-too expensive initial purchase, two different watches can be generated on the CNC, either of which would be a welcome addition to many people's collection.
My flag is firmly planted in support of this extraordinarily clinical yet beautiful design.
