Swiss assembly, 80-hour power reserves (Tissot Powermatic 80), ISO 6425 certified divers (Seiko Prospex), and sapphire as the norm rather than the exception. In spec points that is at most +5 for the long reserve, +6 for Swiss origin and +3 for ISO certification over a Japanese 41-hour automatic.
Above $300 the automatics catch up on hardware: sapphire and 200 m are common, so the choice comes down to whether you want a mechanical movement. Solar and high-accuracy quartz rivals are on the under $500 page.
