I Love this watch. I tried a gen on in March. Decided not to purchase due to the 45 being too big, especially at 16.5mm thick.
The AD never mentioned to me a 43 version at that time. I would have thought he would if he was trying to make a future sale, but its possible they didn’t know yet.
I think 2mm difference makes a huge impact.. probably the factor is the 16.5mm thickness.. it will make the overall look much chunkier and larger.. I bought the 43mm piece too..
