Well after waiting 3 months, my IWC Mark XVIII Tribute XI finally arrived!
So far, I'm really enjoying it and it does look much better in-person than the press photos, especially the olive nato strap colour. I also own the Mark XVIII LPP and I'm glad to say that the two pieces look extremely different, and can happily co-exit happily in my collection. I did note that the lume on the Tribute is evenly applied which wasn't the case for LPP so thumbs up there.
Can't seem to figure out how to attach images but I've uploaded some pics here: www.flickr.com/photos/130224234@N08/albums/72157687231938520
Shout out to Pernilla and Jarvis from the Miami Boutique as well as Peter's team at the Toronto Yorkdale boutique for making the purchase experience so pleasant.
