Much to our satisfaction, we have seen smaller watches re-emerged over the past few years. Even Panerai, known to be on the large side, has been downsizing its iconic design, with its 42mm Luminor Due, which is now offered for the first time in a handsome, light-weight titanium version. We go hands-on with the slender PAM00728 or Panerai Luminor Due 3 Days Titanio 42mm.
