[Question] Getting married soon! Need suggestions for a 38-40mm diver.

Hello, I am a noob when it comes to Seikos so I apologize if this is a common question. I am getting married in a few months and want to get a nicer watch for the wedding. Up until this point, my watch collection has been mostly budget Casios (which I love). I have a skinny wrist so I am more interested in a diver that won’t look too bulky on me. Does anyone have any suggestions? The most affordable/best value is preferred if possible but I know watches can vary greatly in price. I do not mind shopping the used market if you have any suggestions on which one to look for. Thanks!
