As many of you many know I purchased both galliera mono gm and azur pm a few weeks ago.* I wore both equally.* My galliera gm was getting a lot of black blacks due to those brass rings rubbing against the vachetta in LESS THAN A MONTH!* However, my galliera azur pm still look like new with no black marks, WHAT A SHOCKER!* I examined the rings very closely and there were two plastic shields in the middle of each ring preventing brass rings rubbing on vachetta.* I'm happy to report that so far, those plastic shields actually worked!* I will bring my galliera in tomorrow and ask them to replace it with the new and improved rings and leather trim.***
