南非采购需求：电子表，男士，按系列选购

I'm interested in exploring pricing options for Naviforce watches. Could you provide me with your current rates and any available discounts for bulk purchases? Additionally, if you have a catalog or product list, that would be super helpful! Also, I'd like to know about the available models, specifications, and any warranty or return policies you offer. I'm looking to make a significant order, so details like lead times and payment terms would be great to have. Thanks!
