Got a new ultimate beater few days ago, Casio W-800 (tan display). Dirt-cheap, basic functions only, 100m WR, retro look... Good for cycling, hiking and everyday chores, no worries about being scratched or broken.
My Seiko 5 Military (SNK803) settled at 3-4 secs/day after break-in. Excellent workhorse with 7s26 movement, I just love it.
Cheers
I too have a Seiko 5 (same model) and while it is on the "smaller" size range it is definitely a fantastic watch for the price with that excellent proven workhorse of a movement. Can't go wrong with that one!!!
