The most used accessory in men’s fashion is wrist watch. They can also be used to show your style and personality.
Plastic and colorful straps are fine for fun purposes but it would be wiser to use metallic or leather straps for daily use and special events.
Gold colored straps can make you look older than you actually are. If you want to use gold, choose the models that has silver and gold together.
It is also very important that your watch matches your outfit, especially with your shirt and suit. Going with the same color you use for your shoes and belt will help you achieve a complete look.
