Great finish

This was a great product to finish my gold skeleton project for a NH71 watch that is a little dressy. I rarely place display caseback, but wanted to utilize for his time. This was a nice one that worked with the other case that I used from Modmode. Great caseback would buy again.

paired with a slim bezel and the GS diver case bundle, creates a great feeling at miminal bulk. Love the result!!!
