I was looking for a personal-use Railmaster for some time now, but was deciding between the XXL and the 41mm. Yesterday I decided to go with a 41mm, but forgot to turn off my snipe bot and won an XXL today. Here's the question - what I got had a black strap instead of brown. I can see pix of the black strap XXL online, but it always refers to the brown strap model number! Also, this morning I discovered a MOP w/ diamonds variant at the Omega site. Does anyone know the model number for this? Mystery model - I've seen enough pictures of the black-strap version so it's probably the original strap that comes with the watch (picture from WUS, NOT the one I bought) 2806.52.37 - what we all recognize as the XXL 2806.72.31 - fancy MOP w/ diamonds 221.53.49.10.01.001 - in red gold
That blue dial is kinda cool. It's called MOP? What is that pattern? Edit, oh, Mother Of Pearl. Looks nice, though I'm not a fan of the diamonds. Sorry I can't help with the strap question.
I had the XXL years ago and it came with the brown strap...not sure about black strap..looks legit though
