Using this Shinola Canfield watch is easy. Just adjust the time by unscrewing the screw - down crown and setting it as you like. Then screw the crown back tightly to keep water out. Remember, this watch has a depth rating of 5 ATM, which means it can handle light splashes and short swims, but don't take it for deep - sea diving. For maintenance, clean the stainless - steel case with a soft, dry cloth regularly to keep it shiny. If the leather strap gets dirty, use a mild leather cleaner. Keep the watch away from strong magnetic fields and extreme temperatures to ensure its proper functioning.
