Gruppo Gamma always delivers!

I’ve bought a lot of watches directly from the maker or authorized dealer. My experience upon receiving and checking it out is typically a mixed bag - things I love, like and some “nits”. Some go overboard on expensive packaging just ends up in storage, the leather straps are almost always a disappointment - short, cheap, etc.

I’ve never been disappointed with Gruppo Gamma Time Instruments. The packaging is just right - relatively inexpensive but effective. When I open it, the watch always sings to me! I get to choose the strap(s) I want, and even better, they are supple and actually fit me!! For those with a see through case like my PN-20, there is nothing like turning the watch over, winding it and seeing the movement come to life! Of course , the very best part is putting it on my wrist!

Beautiful look and elegant classy appearance. In blue perfectly match any outfit.


I love this watch. The color, the bronze, the small seconds, the no-date dial, the hand-wind movement … it’s perfect. I even like the rubber strap, although I have a tan leather on the way from HDStraps. My only complaint is the springbars. I like quick-release bars, but GG uses a bespoke springbar so QR bars are out. The watch came with a spare set of bars, so it’s off to my jeweler. This is my second GG and I’ll probably get another down the road. They make a great timepiece.
