This will be the only watch I wear so I'm particular. As you can tell I'm partial to the military type designs. Those new CWC's are beyond my budget but would love a used one. Below is what I'm shooting for:

thickness: 10mm to 12mm
width: 38ish to 40ish mm
movement: prefer quartz but not a must
band: titanium or stainless or fabric
water resistance: minimum of 100m
crystal: sapphire

It needs to be tough as nails so probably a diver. I appreciate any advice or recommendations
