Genuine Mitsukoshi Speedy - warranty card check

I have an opportunity to purchase what I'm told is a genuine mitsukoshi speedmaster.

I have attached a photo of the warranty card. I couldn't find any reference photos of what it should look like. Do any experts on here know if it's correct? I can't read Japanese either, does the text in the jeweller field indicate that it's from Mitsukoshi?

Additionally, I heard that genuine mitsukoshi has a hesalite crystal. This might be a stupid question but how would I tell that it's a hesalite crystal in person? I've only ever owned/handled sapphire watches.

Also does anyone know of any useful webpage that does a deep dive into the genuine mitsukoshi?

That says it's from the Hiroshima Mitsukoshi watch salon. So the card looks right. You'd need someone with access to extranet to check the serial to confirm it's a legit Mitsukoshi that's the quickest way.

Would they do it even if I don't have the watch (ie before purchase)? Do I drop in to a boutique and just ask "hey can you check this serial number for me?"

The name "Mitsukoshi" is written in Japanese Kanji characters as "三越".
