this 50/60 series of protreks is really tempting- they are around 42-43mm in case size, closer to 47-48mm from the left sensor across to the edge of the crown. L2L is apprx 50.5mm and they are around 13.5mm thick
has all the bells and whistles like the triple sensor (ABC/temp), tough solar, multi-band 6 atomic timekeeping, screw down crown.
I will probably wait awhile until the price drops on these before I pick one up but these are really tempting. I loved the 600 series one I had a few months back but the size of it was a little larger than I liked for an everyday kind of watch, so it mostly sat in the drawer. I could see wearing this smaller model much more often.

here are some reviews:
