The Alpine Eagle has a glare-proof, flat, sapphire crystal which helps the owner to admire all of the fine details on the textured dial, as well as the gilded applied hour-markers and numerals link which are enhanced by Super-LumiNova (as are the gold-plated, baton-style hours and minutes hands). The arrow-type seconds hand with eagle link feather counterweight is made of bronze and also plated with yellow gold. The date window is displayed between four and five o'clock with a gold disc to match the link dial.

As for verifying provenance well. link There was nothing inside the watch that I worked on that would link have gone Oh link thats from him Perrett told me other than it was exquisite. I honestly have no idea how they made it so well. The quality is just phenomenal.
