I have a Venu 2 and an Epix 2. My Marq 2 Captain arrived 2 days ago. Here some pics comparing the Marq and Epix.
Initial impressions...
The Marq is a little big heavier. Weighting them without the straps its about 12g heavier. I noticed it a little bit initially compared to the Epix, but after wearing it for a bit it feels fine. I was concerned about the face being 0.1" smaller and while yes if you put them next to each other you can see it, but as I saw someone else say, once its on and alone you don't notice it at all. Also because the watch is thicker/chunkier I think the slightly smaller diameter makes it a more overall appropriate size. The crystal is slightly domed, but it's also set down into the bezel just slightly so it just barely stick up above it with its domes part. I don't quite understand why, but the Marq face does seem a bit clearer when I look at it. The base face with the knots on the bottom that they use in all the ads is certainly very pretty, but unless you have a need to know wind direction it's somewhat useless as far as a data face and you can't change the knots data option. It's such a pretty watch that I feel like it deserves a little fancier face than the one I've been using on my Epix that seems like more of a tool watch face shown below even I think it's more functional with ease of finding the data. The jacquard strap is nice, although not $300 nice to buy a second one. In the end, while certainly very expensive I'm happy with the purchase. My dad has a Aviator on the way.
Side note - this forum software is rather wonky for uploading pics so hopefully they come out ok on here.
