i can recommend the Seiko 5 strongly. the autos keep good time and i find the more i wear them the better regulated they become. even if you don't wear it often, changing the time and date are not too difficult. there's debate as to wear them more, put on a winder or not at all and how this affects the gear's wear and tear. i think Seiko 5s are inexpensive enough that these questions don't matter. i would think Invictas and Orients will be similar in function, form and concept. best...
