阿拉伯联合酋长国采购需求：男士石英计时表，按系列选购，选购

I'm interested in purchasing a black and gold watch, but I need some more details to help me make a decision. Could you provide information about the styles you have available in this color combination? I'm particularly keen to know about the features, materials used, and any warranty options. If you have images, that would be great too! It would help to compare the different options you offer. Additionally, I'd appreciate it if you could share pricing information and any bulk order discounts, as I might consider ordering more in the future. Let me know about your lead times for shipping as well. Looking forward to your response so I can proceed with my purchase. Thanks!
