38 mm size is comfortable yet the case accommodates Seiko sea urchin dial in good proportion. Also the case looks well with W&S straight end FKM rubber strap in my opinion.
Don’t hesitate to deal with them, they’re amazing with customer service and their parts are really nicely finished and have a premium feel to them
