Great point, i've noticed this alot recently as i'm researching - looking to buy one at the moment. It's clearly not obvious to many as when you mention this often the owners are sure their crystal is on the correct way. I think the correct way looks better as it follows the case curve, but each to their own...!

: Hi all,

: In studying the photos of many many Monacos I have found out that
: there are quite a few where the crystal is mounted wrongly.The
: original way is to have the curved side there where the lugs
: are, following the curved shape of the casing .There are many
: however - also among us collectors- where the curved side of the
: crystal is mounted on the same side as the crown and pushers.
: Also on some of the photos of this great web site I have noticed
: some that are like that .So check your watch if you want your
: Monaco to be 100% like original.

: From a technical point of view there is no problem, should your
: crystal be mounted in the wrong way. So think it over before you
: go to the watchmaker or do it yourself, because every time you
: open up your Monaco is one too much. Some also think a Monaco
: with the curved side along the side where the crown is looks
: better. So think it over.

: The only original however is as described above. Thanks Abel for
: your input and Fabienne in confirming.

: Cheers to all
