Hi! Great research! Just a little mistake... The Rolex 126712CHNR is a 126711CHNR. Which brings me to a question, has anyone noticed that there are two types of bezels on the CHNR? Unlike the BLRO where the ceramic has different colour, I've noticed two types of PVD colour intensity on the CHNR making the newer ones seem lighter! Just to share what I've noticed and wondering if anyone else has... Cheers! Seb
