I have a Clean Factory Submariner 41 with a VR3235 movement that I wear 24/7. Since it was running 30 seconds slow, I had it adjusted by my watchmaker who improved it to 11 seconds slow. I'm thinking about taking it back to my watchmaker to get it dialed in even more precisely to COSC specifications of plus or minus 2 seconds per day. Am I being realistic, or should I realize I'm wearing a replica and adjust my expectations accordingly? Either way, I love the watch and use it as my daily driver.
