Very nice to play the « jeu des 7 différences ». The size of the segments of the bezel is not the same (larger on the blue one), the Memovox writing is at 12 o’clock when not upside down like on your pic, it is at 6 o’clock on the grey one, one is JLC the other is Lecoultre, without mentioning the difference on the graduation of the bezel as you rightly mentioned… You can continue the game 😉
