New Launch! SRPK 38mm Seiko 5 Sports Sapphire Crystal CT142 Now Live! Couple improvements made below:

1.) Sapphire Crystal
2.) Added .1mm to the thickness helping with the sunken crystal look
3.) Reduced Bevel to widen out surface and minimize distraction

Enjoy! Also, SKX013 inserts fit! In this post we have our CT142 Clear AR crystal with the CT665 insert.
