HR makes a nice watch, but the crystal and bezel are problematic. I had same issues that JoeyB describes above. Will not accept gen spec parts without modifications. Insert size was not even close. Plexi would need to be modded and glued on. A nice piece but somewhat stuck with their parts. I know some have pulled off some pretty nice budgets builds with these case sets, but my research really showed that to do a franken with gen parts, a high cost gen spec case set is needed.
