[N Factory V5 Edition] IWC Portugieser IW371417 Yacht Club automatic mechanical 7750 chronograph questions & reviews

May I ask what material the watch crystal is made of?

Does this model come with a steel bracelet?

The watch timing function is very good, the pushers are easy to press, and although it has many features, the dial still looks uncluttered, very delicate and clean. I have been wearing it for several days and I am so excited. Wearing it to work feels utterly fantastic. Haha! The shop's items are truly great. I personally highly recommend everyone to give it a try.

The newly arrived IWC13, looks very nice and is pretty much indistinguishable from the genuine watch. Having listened to it, it certainly has a 28800 beat rate, but the movement feels quite different from the real one, and the chronograph pusher is a bit stiff.
