The step from $200 to $300 mostly buys a sapphire crystal (Orient Kamasu), a 200 m dive rating with a screw-down crown, or a steel bracelet instead of a strap. Movements are the same Seiko 4R36 / NH35 and Orient F6922 families as the tier below.
At $300 a quartz watch can offer sapphire, solar charging and 200 m (Citizen Promaster, Seiko Solar divers). Choose the automatic for the mechanical movement itself; the quartz rivals are on the under $300 page.
