I chose the 141 for both its size and its looks. I have a teeny tiny wrist, so the larger Rads (45mm and up) were out of the question. None of the 40mm Rads really grabbed me with their looks -- I was actually looking at a 98 originally (I didn't even know about the 141 and thought the GMT/Alarm features of the 98 would be nice to have). But then I happened to spot a picture of the 141 on another site and was instantly hooked. I've always liked the silver small seconds dial on some of the Luminor models and I also thought the metal outlined markers on the 141 looked really sharp. So, I decided I would at least attempt to find a 141 before settling for a different model. Luckily, I was successful in my search.
I'm pretty happy to own 1 Luminor and 1 Rad -- a nice balanced collection, I think. Now I can concentrate on building up my strap collection for a while : )
Have a great day everyone,
