I always considered the Big Pilot too big for me, although when trying one on I found it to wear surprisingly comfortable. I have two 45 mm watches that I really like, and what is 1 mm to reach the size of the Big Pilot.
At 44 mm the Vintage Collection Pilot's watch is slightly smaller, at about 12 mm thick it is slimmer than the Big Pilot, it also is lighter. I own this watch, it is very comfortable to wear. It looks a bit different from most Pilot's watches and, most importantly, it appealed to me very much. The Jones calibre that can be admired is a bonus too.
You probably know about the technical differences between these watches, so I will not mention them here. Both are great watches. If I had to choose again, I again would choose the Vintage Collection Pilot's watch. Good luck!
Kind regards,
Paul
