I am owner of this watch store bought it a few years ago.
I bought the same on amazon because I like the look of this shows that we do not find more in store.
The store bought is for compensation for change of striped mineral glass and change lhorlogerie (delay in the time display)
The mineral glass is very fragile and scratches more easily which is why these watches with this type of glass are cheap.
However, I ordered an additional mineral glass in store for the future. However, there apparently has great difficulty in obtaining it. SAV problematic depending on the manufacturer and its monitoring over time of watches sold on the market.
