I'm a wrist watch guy- Collecting vintage watches is a hobby, just like cues for me. I have found that the best watch to wear while playing pool is one that sits flat on the wrist and is lighter in weight. The modern big round face watches are not great for wearing while playing pool. The Cartier TANK style watches work best- but you don't need to spend $15K on a Cartier- Seiko makes a line of non- battery Photo cell- solar- watches in tank style that -, I feel, are ideal for pool- lightweight, and sits very flat on the wrist.
