I know I'm some weird supervillain in this circle jerk of a topic but the dial is .3mm bigger. If you think .3mm is somehow not perceptible to the human eye then you really need to get some prescription glasses.
Mate I have a Gen 126613LN and dial size if different is definitely not perceptible n trust me I myself is a super OCD for fine details....although my opinion is mine n each to its own, so yo can nitpick what you want whether on lugs or on bezel or dial diameters
