Slim, understated profile with metal case and leather strap.
When you’re attending a formal event—anything from a traditional wedding to a black tie event—classic and understated is best.
Your accessories should match the formality of the event itself, and when it comes to your watch, a simple style with a light-colored face and black/brown leather strap is perfect. (It goes without saying that your leather shoes and belt should also be black!)
For “dressy casual” or business casual situations when you’re still in a suit and / or tie, a similar watch with brown leather band would fit the bill.
