March LA.B Mansart Petite Seconde

The March LA.B Mansart Petite Seconde is praised for its creative, unique, and classy design, with reviewers highlighting its distinctive octagonal-meets-square case and impressive finishing. Owners find the 35mm case size and 39mm lug-to-lug measurement manageable for wear. Some reviewers note that the lack of a minute track and a potentially short minute hand can make precise time-setting challenging, and one reviewer found the bracelet clasp fiddly. The watch is powered by the automatic La Joux-Perret G121 caliber. Overall, owners and reviewers appreciate the March LA.B Mansart Petite Seconde for its distinctive styling and finishing.
