Monoblock vs Non-monoblock crown?
At the bottom of this excellent post there is an image illustrating the various crown types.
What exactly is the difference between these two types? Rolex Serial Numbers By Year/Clasp Codes - Crown Markings https://r.tapatalk.com/shareLink?sha...hp%3Ft%3D54362 Sent from my cracked, broken, hand wound Phone |

"The old gold crowns were sheet gold sandwich wrapped around a steel threaded core..
The new "monobloc" crowns are solid 18k gold and machined out in the center and a SS threaded insert pressed in." Found that on a post https://www.rolexforums.com/showthread.php?t=149692 |

Should this be moved to the watch tech forum, for future reference?
