This is the updated 41mm Submariner Date ref. 126610LN, and yes, Rolex have managed to make it even better! Although 1mm wider in diameter, Rolex have slimmed the case lugs and subtly reduced the crown guards, the result is a more comfortable watch on the wrist, and with better aesthetics. The little Rolex coronet on the black luminous dial between 'SWISS MADE', is a visual clue this latest Sub Date is powered by the new 3235 calibre with an extra day's (72hr) power-reserve, water-resistance is unchanged at 300m. Under Rolex warranty for 4 years, and complete with its Rolex box, Sub instruction booklet and Rolex warranty certificate.
