GMS Sunglasses Collection

GMS, short for “Glasses Masunaga Special,” is a heritage line born from Masunaga’s century-long tradition of excellence in eyewear. Introduced in 1933, GMS was originally crafted for the Japanese Imperial family and remains a symbol of prestige, refinement, and meticulous craftsmanship.

Each pair is handcrafted in Fukui, Japan, taking six months and more than 200 precise steps—guided by 150 dedicated artisans from start to finish. GMS frames balance timeless Japanese aesthetics with exceptional comfort and durability, offering eyewear that is as distinguished as its legacy.
