Although I was OP, I can in no way take credit for the invaluable hour index info in this thread. https://omegaforums.net/threads/arrowhead-markers-other-names.72330/
Black dial Railmaster, White dial Railmaster, Seamaster Chronometre, Black dial Constellation? I hate you.
C'mon man.. Your the expert.. I know you know more about this stuff than me! But I say that cuz the first one doesn't have the big silver retainer ring like the railmaster have, and the case is more flatter like a seamaster. I think the second is a railmaster.
I’ll take that as a joisey compliment so thank you these are very much my favorites in the stable. As others said the first two are Ranchero and Railmaster. I’ll make another version and add the black Ranchero. The white 2777 Railmaster is still just a dream unfortunately.
I haven’t found the right one yet, feel free to send that one over and I’ll include it in the next version
