加拿大采购需求：LED手表，红色手表，军表，男士手表，粉色手表，金色手表

I am reaching out regarding an issue I'm experiencing with one of your products. It seems that I'm unable to get the digital display to illuminate. I've tried pressing the designated button, but nothing happens. It's quite important for me that the digital characters are lit up at all times for better visibility. Could you please provide some guidance or troubleshooting steps to resolve this issue? I would appreciate any advice on how to ensure that the display remains illuminated. Thank you for your assistance in this matter; I'm looking forward to your prompt reply.
