Then, congrats on your first Patek, too. I am not sure the 5134 is under appreciated, though. It has its charm and interest, it cannot compete with the 5110 which is a totally different watch. It has a friendly complication, a nice manual winding movement, and yes, a too big case ( compared to the movement, or is the movement which too small compared to the case.
) and a date would ruin the symmetry of this dial, so, a good point that it doesn't have a date.
