Two very different pieces
the 5105 had the Vintage calibre 9’90”
One of yhe best ever movements and a Vintage inspired case
The 5100 has a modern 10 day movement and possibly one of my top 5 modern PP with Vintage inspired case
Both are amazing
One is classically sized
The other has modern proportions
Depends what are you looking for,
A modern vintage
Or modern inspired by Vintage
Best
