1997 Seiko 5H23-8160 'Micro Tuna'

Having hiked through the Rockies in the winter, a reliable watch is essential. A slight deviation in time is the difference between safely arriving at your destination, or being stranded in the winter night of an unforgiving environment. The Seiko 5H23-8160 is about as reliable and rugged a watch can get. A reinforced steel case houses the Seiko movement 5H23, a movement accurate to ± 15 seconds a month, a quick-set day/date complication, and a EOL (End Of Life) battery indicator which ensures you’ll never be caught off guard with a dead battery. But there is a reason this watch has one more feature up it’s sleeve; a bezel guard, that’s right this watch has two bezel guards protecting the bezel from accidental bumps which may cause the bezel to rotate, add the 10bar water resistance and screw down crown and you have a watch that can accompany you from the sea to the ridges of the Rockies, and all while looking great. 

Dimensions/ Wrist Size fit: 38mm, 40mm with crown, 11mm height, 18mm lug to lug width. Watch suits wrists from around 6 inches to 8.5 inches. Comes with extra links to fit your wrist.
