As my contribution to this "hot" subject, let me present you some pictures of a genuine Explorer 1655 next to a "Franken" GMT Master 1675 fitted with Explorer dial, hands a bezel. Neither do I have Jocke's sense of humor or photographic skills...but I hop...
Its post like this one, which help us to see the difference. With your comparisons, even I could see the difference in the crown guards. Thanks once again. Regards Tony
