It starts with the most obvious differentiating feature (whether the Omega logo on the dial is applied or printed) to progressively narrow the list of potential “suspects” until it arrives at a perfect match, of course assuming all parts from the watch under examination are indeed original. The whole process is very impressive, and gives a playful spin to the considerable knowledge required in the world of vintage Speedies. 

In the end, the Identification Program not only provides one of the smoothest integrations I’ve ever seen of geeky horological facts, but it also bring a great deal of value to the collector community. It would very obviously be a fantastic tool for many more wristwatches that offer the same extremely long production period with subtle variations, and with many franken configurations. Did someone just whisper “Please do it for the Rolex Submariner”?
