Your Corino looks great Joey, is that one of your dials? Wow
The crystals are both correct, the tropic 38 was used early on, it's a super dome with no cyclops! They did use gilt dials until 66 I believe but the pcg's stopped in 63 and with them so did the swiss only radium dials.. For a 61 like mine it shouldn't have the later swiss t<25 dial but it's still ok, would have been changed during a service for example.
Thanks Whoop, You make a lot of sense, essentially gilt is gilt and it's gilt
