巴基斯坦采购需求：男士，石英计时手表，按系列选购，选购

I'm interested in the men's sports quartz chronograph watch featuring a luminous hollow dial, waterproof design, and date/stopwatch functions. Before placing a bulk order, I would like to request a sample to assess the quality and functionality. Specifically, I'm looking for a sample in black and copper color. Please let me know if you can provide this sample and any related costs or shipping details. Looking forward to your prompt response. Thanks!
