Great watch. Looks unpolished. I have a 2.38 mark 4 as well. I have always been told that a mark 4 in a 2.38 case is likely a replaced dial. I have now seen a few since I bought mine. I have also seen a 2.40 ff brown dial in the possession of a well known dealer......so is it possible that a 2.38 can have an organic mark 4 dial. We have seen the gmt dial guidelines largely debunked over time......is it time to do the same with the well known drsd article about red sub number guidelines? My baby is attached!
