“This is a watch that never made it to the Squale catalogue of watch models. It is one of a few variations of Ref. 1521 test-watches that were not considered further for mass production. These watches came to me directly from Squale, so there is no doubt about their authenticity. They were found during an office move in Milano and offered to me. Whether you call them test-models or prototypes, they are variations that were produced by Squale. I also have another one with a grey dial, listed separately. Since they never made it to production, these are pretty rare watches. All the photos are in natural light so you can enjoy the beautiful blue dial. Other than the camera photos, I also made some with my iPhone, holding the watch in the sun, so you can see how the colours are a little different depending on the camera and lighting conditions. Below you will find the specifications and further down I am listing some differences they have from the catalogue Ref. 1521 models. If I notice any other differences later, I will add them to the description. Any more questions, feel free to ask me.
