If only it was 4 or 5 mm smaller, I would have grabbed one!

That design wise they made it look good, I am fully with you - thereโ€™s no reason why it couldnโ€™t have been even 10mm smaller ๐Ÿ˜‰ The Minerva movement inside is truly lovely, too ๐Ÿ‘Œ๐Ÿป๐Ÿ‘๐Ÿป

But youโ€™d lose none of the functionality or legibility at 42mm ๐Ÿ˜‰

I really enjoyed wearing the 42mm Mare Nostrum... but gimme this one in 42mm and I'm sold for sure!

But then I'm not at all into this brand, so it's just a first sight impression.

Mine was the 2000s reissue. A lot cheaper that way!

..as big as it was, in the original design, I've never considered buying one (same applied also to the earlier brother PAM300) The cost, for a "show" model (no way I would have used it) was prohibitive, for me. I had already bought the 341 Egiziano, which cost was a bit more approachable. Never regretted my decision, though.
