Well Ventura (preciluxe) came through, they are supplying me with a replacement clasp for 80 euro. I also needed a ceramic alarm plate as the last time I changed the battery I discovered mine had disintegrated, they tried to tell me that they couldn't sell me this part and I would need to send the watch to them for a technician to fit it, luckily I managed to convince them that I know what I'm doing and can fit it myself, so they're supplying me with this too, for around 20 euro
