Hi guys, I bought this "THE Chrono" series Swatch at a second hand store but I cannot find what its exact model is. The inner dial appears to be a "Side Protection" (YCN4003AG) model, while the outer dial resembles a "Mat Rebeaud" (YOZ100) model but with silver color instead of gold. The casing and crown is stainless silver but the buttons are gold. I'm starting to think it might be a watch fiddled around by a watch artisan? Thanks in advance!
