Timeless elegance in consummate form: with three hands and a discreet date display, this simple automatic watch has established itself as one of the most popular Portofino models.
The Portofino Automatic with a black dial and black alligator leather strap is optionally available with a Milanaise mesh bracelet in stainless steel. The solid, mechanical automatic movement reliably ticks away the time. The evenly rounded sides of the 40-millimetre stainless-steel case make it appear even slimmer.

Really Great Watch
I picked up a Seiko for daily use and I’m seriously impressed. Keeps perfect time, looks clean, and feels durable. You can tell it’s built to last.

Feels Super Legit
Was nervous buying a Versace online but this one’s 100% real. It has a nice weight, and the face is stunning. I get compliments every time I wear it.

Amazing Deal
Scored a gorgeous Gucci piece for way less than retail. Brand new, boxed, and certified. Will recommend this store to my friends for sure.
