Actually, I believe so... But didn't know about the above.
A year and half ago, I had a nasty scratch that was bothering me, I tried to polywatch it without success! So took to a Junghans AD for a crystal change... 50€ later it was done, and now I scratched it again! I'm not changing it again immediately.
God knows what I do with this watch as I don't scratch my others watches !
Just to make sure I got this... You asked for a sapphire crystal rather than the plexi?
The latest versions come with sapphire: https://www.junghans.de/en/collection/watches/junghans-max-bill/max-bill-handaufzug/27370102?c=484
I bought mine used, but it was only 3 months old. I don't know if the new sapphire crystals are compatible with the older cases.
I think you will be happy with the sapphire. I really like a big domed plexi crystal and was afraid the sapphire would not have the same clarity and charm. They did a really good job with the high double dome and AR coatings.
I'm breaking a rule or two by sharing a 37mm watch (and what could arguably be called an homage) but the short lugs (just shy of 40mm lug-to-lug) make this Dan Henry 1975 an adorable option ($260-280 for the meca-quartz) that wears small.
Thanks for the feedback, as I really like the watch and I haven't worn it much in the past months because I was not sure what to do with it.
Can I ask you how much the sapphire cost?
