This is for sale locally. It’s a little high priced but complete. I have a question. I thought these sapphire case backs came with a sapphire crystal. This one isn’t. Does the watch match the reference?
What is for sale? You've given us next to nothing to go on, but there was a version that had a Sapphire back but Hesalite (plastic) crystal available a few years back. The 3572.50 was one but there are also limited editions with that spec too. Quite desirable but not super rare. More recently the display back models have come with sapphire front and back.
