What does “BLRO” mean?

BLRO is the Rolex suffix for a blue and red bezel, from the French 'bleu rouge', the combination collectors call the 'Pepsi'. It appears on modern GMT-Master II references with two-colour ceramic bezels, including the white gold 116719BLRO, introduced in 2014 as the first red and blue ceramic bezel, the steel 126710BLRO from 2018, and the white gold 126719BLRO.

Making red and blue in a single piece of ceramic was technically difficult, which is part of why these bezels are prized. Older Pepsi GMTs with aluminium inserts, such as the 1675 and 16710, don't carry the BLRO suffix, so dealers use the nickname together with the reference for vintage pieces. On the steel 126710BLRO, the Jubilee and Oyster versions share one reference, so state the bracelet separately. Ceramic doesn't fade like aluminium, but it can chip if knocked, so check the bezel edges in photos.
