Seiko's low-end watches are of the same level as Citizen, and they are only better than the movement. Citizen now mainly develops light kinetic energy and light wave watches, and Seiko mainly develops mechanical watches. Seiko's Guido series is of the same level as Swiss high-end watches, followed by 6R movement and Swiss low-end ETA movement. In the second place, 4R movement feels better than Citizen 82 movement, but Citizen 82 movement is higher than Seiko. Citizen 9 movement should be of the same grade as Seiko 6R movement

Japanese mechanical watch grade

Seiko Guido (equivalent to Swiss high-end)

Seiko 6R, Citizen 9 (approximately equivalent to Swiss low-end ETA movement) 3. Seiko 4R, Citizen 415 4. Citizen 82 5. Seiko 7S

Citizen light wave, light kinetic energy, and so on. This is the high-end of two brands.

Whether you like Shi Ying or mechanical watches, it should be said that they are not comparable.

Also, depending on the landlord's budget, I can help you advise. If you choose Seiko for mechanical watches, Citizen for light kinetic energy.
