The Gruppo Gamma Peacemaker is one of the brand’s most enduring collections, and one of the easiest to recommend to a first-time buyer. Its 2017 debut revisited a Vanguard-era concept first drawn in 2014, and it has since grown into a family spanning stainless steel, aged steel and marine-grade CuSn8 bronze references.
If you are comparing Peacemaker options at Mi-Watch, here is what actually differs between them, and what stays the same.
A cushion-cased tribute to 1940s frogman watches
The Peacemaker’s cushion case and restrained dial layout trace back to the dive watches used by military frogmen in the 1940s. Gruppo Gamma’s own styling, sandwich dial construction and Swiss mechanical movements give the collection its identity, distinct from the more overtly tool-watch Vanguard.
Case sizes across the current Peacemaker range run 43 mm and 44 mm, with a lug-to-lug of approximately 52 mm to 52.5 mm and a thickness of 13 mm to 14.5 mm depending on the reference. Every current Peacemaker uses a 24 mm lug width and is rated to 200 m water resistance.
Steel or bronze: the two Peacemaker paths
The clearest decision when buying a Peacemaker is case material.
Stainless steel and polished steel references, such as the limited-edition P-03L RLE2, keep a consistent, low-maintenance finish for the life of the watch. They suit buyers who want the Peacemaker’s proportions without the upkeep that bronze requires.
CuSn8 bronze references, including the PN-07, PN-19 and PN-20, will darken and develop a natural patina with wear and exposure. No two bronze Peacemakers will age identically. If you are new to bronze watches, our guide to Gruppo Gamma bronze watches and natural patina covers how the patina develops and how to care for it.
Automatic or hand-wound
Peacemaker movements come from two Swiss suppliers, depending on the reference:
- ETA 2824-2 and ETA 2824-2 élaboré — automatic movements used on the steel and some bronze references.
- Sellita SW219-1 — a hand-wound movement used on the current bronze hand-wound Peacemakers (PN-19, PN-20).
A hand-wound Peacemaker asks for a daily wind and suits collectors who enjoy that ritual. An automatic reference is the more convenient choice for everyday wear.

Gruppo Gamma Peacemaker FAQ
What size is the Gruppo Gamma Peacemaker?
Current references measure 43 mm or 44 mm in diameter, approximately 52 mm to 52.5 mm lug-to-lug, with a 24 mm lug width.
What movement does the Peacemaker use?
Depending on the reference, either a Swiss ETA 2824-2 or ETA 2824-2 élaboré automatic movement, or a Swiss Sellita SW219-1 hand-wound movement.
Will a bronze Peacemaker change colour?
Yes. CuSn8 bronze develops a natural patina with wear and air exposure. This is expected and part of the appeal of bronze watches; see our bronze watches guide for care tips.
What is the water resistance of the Peacemaker?
Current references are rated to 200 m.
Final thoughts
The Peacemaker’s core appeal has not changed since 2017: a comfortable, versatile cushion case with a design that works with a wide range of styles. The main decisions are steel versus bronze, and automatic versus hand-wound. Once you have settled those two questions, the rest comes down to dial colour and current availability.
