shadowprince2000,
You showed some rare watches.
Opal is brittle and difficult to make big dials so we usually get ladies' watches with opal dial. A larger watch is rare indeed.
Lapis lazuli dial is in a very rare shaped case and bracelet combination; I have only seen that shape in Piaget museum and not in the real world. You must live in a museum!
Finally, the jade dial watch has a iconic gold woven bracelet that Piaget.
The bracelet design is from decades ago but Piaget could revive the design in 2013 with a small technical improvement. Now, the size can be adjusted by the local service centre instead of being sent back to Geneva for permanent alteration by the bracelet specialist.
Thank you for showing us some exquisite rare pieces do exist outside Piaget museum.
Regards,
MTF
PS. I made some typing edits to your post.
