Buying notes
- The Seiko 5 is popular and easy to resell, but its 100 m water resistance and push-pull crown make it less of a true diver.
- The Orient Kamasu usually wins on sapphire crystal, automatic movement value and enthusiast credibility under $300.
- The Citizen Promaster Eco-Drive is the easiest daily tool watch because there is no automatic servicing worry and it has true diver credentials.
