It's spectacular in-person. I tried it on at an Omega Boutique in California a couple years back. It wore very comfortably, and its lug-to-lug made it manageable for a 6.75 wrist. The combination of the rose gold bezel ring, dial patterns, and red text is an A+ design in my view.
Movement-wise, the actuation on its column-wheel chronograph is a notable upgrade over the 1861/1863. I'm not well-versed in all of the technical achievements of the 9300. But from a subjective user experience POV, the 'click/snap' of the 9300 chrono pushers felt much smoother than the 186x.
If it was priced within a couple thousand of the standard moon-watch, I probably would've added it to my collection by now. But unfortunately it's priced at a 3x multiple over the standard moonwatch 馃檨
A couple years ago, I remember seeing grey-market FS offers for BNIB examples at 40% off the MSRP. I'd recommend the one with the clasp, over the tang buckle.
