I've had my Protek on a orange zulu for a while so decided to convert it into a more dressier version so I can wear it to work (shirt/khakis).
Ordered this 22mm leather nato from Crown-N-Buckle ($15 discounted price but the quality is much better than $30 leather nato's I've purchased in the past from Ebay).
What I love about the newer Protek is Casio's move to use standard 22 lugs (and pins) so strap changes are easy and really changes the entire look of the watch. When I had my Suunto Core last year, I'd change straps like every month till I sold it....couldn't live with the low resolution neg display on it ).
As of recently, I've been wearing my G's more and more and seriously think that automatics are overrated .
But anyho, here are the pics. I, personally love the look.
