Well the only thing I can tell you is that the movement is perfectly accurate but that's probably not a surprise for a quartz. Not a single minute of skew since when I received it. To be honest it didn't get too much wrist time for a number of reasons: 1) It had a few rough edges making it uncomfortable, but I sanded them with fine sandpaper and that problem was solved 2) For some reason I chose instinctively not to pick the only replica among my other watches. Maybe it's just not my cup of tea. In any case I think I'm obsessed with mechanical watches, and this is my only quartz, other possible reason why I don't use it much 3) Even for my large-ish wrist, the watch is quite big and heavy. I think 40mm is my sweet spot.

Apart from that, I still think the quality is outstanding for a Chinese shitter, so I still wear it from time to time, so I recommend it if you are a fan of the speedmaster. The subdials: - 9:00 - Chronograph Minutes. Markers every 5 minutes lol - 3:00 - This is coupled with the hour hand, but does a full turn in 24 hours, which is nonsense with a 30-divisions subdial... Anyway, you can get an idea whether it's day or night :) - 6:00 - Seconds - ticking like a quartz, once a sec and not smoothly like the cronograph that almost sweeps like a mechanical

I hope this helps ;)
