Hoping some of you can offer recommendations on upgrading bezel insert and Crystal on my Sub. Who's makes the best and how difficult is ut for me to perform these upgrades myself. Thank you in advance.
Easy answer- Rolex makes the best!
Difficulty is relative to your skills. If you’re inexperienced, have a modder do it. If you don’t want to spend gen $, get a Clark’s crystal and a spongebob insert.
