Laid my hands on really large 1.4 inch round ultra-low power transflective color Sharp LCD, will work on it in parallel, as the controls are rather complex. This is a parallel effort and might not be progressing as fast as the rest. Got two in case one breaks. These are super-hard to find, I was very lucky to procure two pieces which were miraculously in stock from a European distributor. Those are used in very high end smartwatches.
