It’s hard to write a comment on a watch I purchased that I never received.
This is a beautiful watch--lovely face, elegant case, easy to read, and provides helpful time and date data, with a bonus moon phase dial for added enjoyment. But as a calendar watch, why is it missing a Perpetual Calendar function? Further, with Atomic Timekeeping, the watch would NEVER NEED SETTING! Just put it on, and it's always accurate for time and date.
I got the watch as a wedding present from my wife. No argument that it is a beautiful timepiece. Love the water resistance, look, and features, but in this price range the crystal should be sapphire. I personally would not buy the watch for that reason.
Changing day, date,month is way to difficult and involved.
