Rugged, Reliable, Functional Form

“A good wristwatch is something I can’t stand to be without. I believe that a watch should look good but most importantly be able to withstand everyday abuse, plus some. Our Seiko Mods are built carefully and precisely to deliver these beliefs!”

Explorers Lead The Way!

Beautiful work, friend! Keep doing what you do, because these babies' are amazing! I'll most likely buy another time piece from you in the future!

Just got the watch yesterday, and we had a great first day together—tennis, swimming, and then dinner…The watch wasn’t out of place at any time. Exactly what I was looking for, a watch to be excited about but not worried about.

This is just plain awesome.

I was apprehensive about ordering a super expensive watch, but the quality, condition, speed and value of the watch was definitely worth it…I am very happy with the purchase and will definitely shop here again!
