Hi there. I got two 300M Ceramic in last month from same seller and they had asian movement and both with 3-4s gain. Interesting, the first had aluminium beezel painted in blue, and the second is a real shiny blue ceramic.
The beezel is misaligned a little bit on both near the 12 o' clock, but is fine from 20cm distance. The bracelei it's fine about a half hour sanding (with 1200 Scotch sandpaper) on the edges and after tightening all screws, but not as good as Noob CrPo bracelet, which is good out of box. The first one had some little scratches on the AR, the second had some little painting "drops" on the dial, but they are only noticed with magnifiying glass.
You never look at reps with magnifiying glass!!
And in final, the second one has misaligned hour markers Overall, from two reps you can make a good one, OR if you had lucky, the first will be perfect. (I haven't too much lucky, i was born in 13
If you not use the magnifiying glass, this is a super rep, i wear one a daily beating, i don't regret this purchase.
Cheers.
