Rolex President 41mm Vs 40mm. Caliber 3255 which is fitted with the optimized geometry chronergy escapement. The movement inside is a fairly new one for rolex.
The new rolex submariner 41mm feels slightly more compact on the wrist than its predecessor. The case of the 2020 submariner as you would guess from a modern rolex is made from oystersteel the internal name for 904l stainless steel. Rolex yacht master i ii.
In my opinion that watch was a bit too big and lacked the finesse and perfect design ratio of the original day date in 36 mm.
Rolex datejust 31mm s steel. Rolex 18k rose gold model 228235chodmip. The extra 1mm in diameter is almost imperceptible and the overall design has a bit more elegance. The rolex day date 40mm was released in baselworld during 2015.
