Ever since I got into watches, the Peacemaker line from Gruppo Gamma has been high on my list. The design language, the dial, and the overall execution just clicked for me, to the point where it became a grail, not because of status or hype, but because it’s a watch I always wanted to add to my collection.

The Peacemaker has been part of the Gruppo Gamma’s story since 2017, introduced after the brand retired its original case family the Genesis(it was made from 2013 to 2017). With this model, they went back to their roots, to the utilitarian design, strong presence, and inspiration drawn from early military dive watches, including those issued to Italian frogmen during World War II.

The dial and the caseback

The Peacemaker arrives in a black canvas pouch and the moment you open it, your eyes are drawn straight to the dial. The fumé finish is truly special, fading from a lighter center to darker edges and changing beautifully with the light. In this green execution, it feels calm and slightly vintage. I would say its perfect in this color.

I chose the green version because it pairs beautifully with the bronze case. The contrast between the two really brings the watch to life, a match made in heaven.

Legibility is excellent thanks to the sandwich dial construction with the golden hour and minutes hands, paired with generous application of Swiss Super-LumiNova. During the day it feels refined and balanced, but at night the Peacemaker really comes alive, reminding you it’s still a serious instrument. It doesn’t take much to get lit up and as you can see it shines bright.

The box-shaped, double-domed sapphire crystal adds character while remaining practical. Sapphire is expensive to work with, but it pays off with excellent scratch resistance, improved shatter resistance, and clear readability thanks to the anti-reflective coating underneath.

Flip the watch over and you’re greeted with something I always appreciate, a see through sapphire display caseback which reveals the movement(more on that later) in full and features Gruppo Gamma’s signature caseback flange. Inspired by submarine portholes, this flange is a defining design element of the brand and is finished to match the case material. It looks amazing in my opinion and really elevates the whole package.

The movement

This version is powered by the Sellita SW219-1, a Swiss hand-wound movement with small seconds and date. Produced by Sellita since 2017, it is based on the proven architecture of the ETA 2800 family.

I really love the small seconds sitting at 9 o’clock, I find it beautiful and refreshing. The movement could have a date at 3 o’clock, but this watch doesn’t have one and honestly, I’m glad. It keeps the fumé dial clean and uninterrupted, letting the colors and texture shine without anything breaking the flow.

Operating at 28,800 bph with a 45-hour power reserve, the SW219-1 offers hacking seconds, reliable performance, and excellent serviceability. Its manual-winding construction keeps the movement simpler and well suited to a tool-oriented watch, especially when displayed through a sapphire caseback.

I chose the hand-wound version because I wanted to slow things down a bit. After wearing mostly automatics, winding the Sellita SW219-1 by hand feels more intentional and more… well let’s say personal. It creates a different bond between the watch and I. That small daily ritual creates a quiet moment where I can actually connect with the timepiece in a deeper sense, not just wear it.

On another note there’s also something reassuring about the simplicity of the fewer parts, and the feeling that nothing is happening unless you make it happen. It’s a modern movement, but it carries that old-school charm that reminds you why mechanical watches are special in the first place.

Although I choose the hand-wound version, if you prefer an automatic movement, the PN-07 and PN-08 are both powered by the ETA 2824-2, which is a true workhorse. In the end, it comes down to personal preference choosing between the more hands-on mechanical experience or the convenience of an automatic.

The bronze case

Speaking of bronze, Gruppo Gamma has been working with it since 2013, long before it became trendy. I have to admit, this is my first time owning a watch made from this material.

The Peacemaker uses marine-grade phosphor bronze (CuSn8), which offers higher strength and corrosion resistance than most bronze alloys. Over time, it develops a natural patina, slowly changing with wear and environment. No two watches will age the same, depends on many factors and that’s exactly the point. The watch becomes yours, visually and emotionally.

At 43mm wide and 13mm thick, well lug to lug is approximately 52mm, this isn’t a small watch by any means, but it wears exactly how you’d expect a proper dive-inspired tool watch. Lug width is 24mm, which is new to me. Never had that wide width in the past. Still on my 17cm wrist it sits comfortable. I have to admit this is the maximum size I can wear.

With its 200-meter water resistance and screw-down crown, the Peacemaker is suitable for swimming, snorkeling, and general water use. For me, that means not having to think twice during everyday dad life. Washing hands, bath time, playground water fights, summer holidays in Vietnam, or spontaneous trips to the pool. It’s the kind of practical water resistance that fits real daily wear, not just the spec sheet.

The strap and comfort on the wrist

Back in the 1980s, long before Panerai became part of the Richemont (then Vendôme) Group, a historically important prototype known as the Mille Metri appeared, fitted with an accordion-style rubber strap. Gruppo Gamma took inspiration from this design and reinterpreted it in a modern way, producing their own version in FKM (fluoro rubber).

The result is a strap that feels properly thought out. The green FKM strap pairs beautifully with the green fumé dial, tying the whole watch together visually. On the wrist, it’s extremely comfortable, it doesn’t push, pinch, or shift around, and once it’s on, it stays exactly where it should. The flexibility of the rubber makes it easy to wear for long periods without any pressure points.

Small details like the debossed Gruppo Gamma logo at the tail of the strap round things out nicely and show that this isn’t just an afterthought, but a strap designed specifically for the Peacemaker.

Finishing things off is a bronze buckle, which not only matches the case perfectly but will also age and patina alongside the watch, not to mention the name of the brand engraved in it.

The watch comes with an extra leather strap. It’s a small but thoughtful detail that shows Gruppo Gamma understands enthusiasts, because let’s be honest, most of us loves swapping straps on our pieces. And it doesn’t hurt that the leather strap looks absolutely spot on with the watch.

Final thoughts

The Peacemaker Bronze has quickly earned a special place in my collection, due to it being my first bronze watch. While it’s not my first experience with a hand-wound movement, it does make wearing it more personal and engaging. The fumé dial is simply mesmerizing and the small seconds subdial at 9 o’clock adds a nice balance and character to the whole package. Winding the SW219-1 has become a little daily ritual I genuinely enjoy, it’s a refreshing contrast to automatics and reminds me why I fell in love with mechanical watches in the first place. The lume is also excellent and provides a good legibility in lower light conditions as well.

Despite its bold presence, the watch is surprisingly practical: the 200m water resistance, screw-down crown mean I don’t have to worry about daily wear, while the bronze continues to develop a patina that will make each watch truly unique. All in all, it’s a beautiful tool watch that’s genuinely fun to wear.

I’ll be updating the blog later with some shots of the patina as it evolves, so you can see how this watch transforms over time and grows alongside its wearer.
