Hello, can a new sapphire crystal make the date appear smaller and more accurate in an old noob and a arf gmt? Also are movements interchangeable if they are both noob submariners. Also if I send my Daytona 4130 In to you can you make the long second hand run without such a notice movement stutter. They all seem to have slight pauses in moving from time to time and it’s quite different from authentic and very noticeable like it’s ticking as a quartz might. Does it need a part ? Can you help ?
Many thanks!
