I know nothing about watches. Nothing. I have an Apple Watch but am interested in picking up something that I can wear in professional settings. I work in tech sales. Rolex’s are common in my industry but they scream douchebag to me. I want something that is well made and that will last. I don’t know watch brands but I’m hoping for something that is nice, will compliment a tailored suit or a blazer OR a black tshirt. And I want a brand that doesn’t scream that I’m trying too hard. TIA.
Another vote for a micro band from me.
Lorier are good - the Astra would suit your needs (based on your description).
Baltic are another as others have said, as are Traska and Farer.
If you are wanting something Swiss any of the entry level Swatch Group Brands are the way to go. The Tissot PRX or Gentleman, the Certina Action Diver, the Hamilton Khaki Auto and the Mido Ocean Star or TV Date are a good place to start.
Or Seiko. Especially the Prospex line - any Alpinist or Prospex Diver is really solid, respectable choice. And will last a lifetime. ☻
