The Gruppo Gamma Peacemaker is one of the brand’s most popular collections. Its comfortable 44 mm case and restrained, versatile design give it an enduring character that works with a wide range of styles.
Introduced in 2017, the Peacemaker revisited an early Vanguard design conceived in 2014 but never brought to production because of an unexpected chain of events. Its form looks back to the dive watches used by frogmen in the 1940s, while Gruppo Gamma’s signature styling gives the collection its own recognisable identity.

Peacemaker
Gruppo Gamma Peacemaker watches combine vintage military-diver proportions with distinctive cushion cases, sandwich dials and Swiss mechanical movements. Introduced in 2017 from a concept first drawn in 2014, the collection has developed into one of Gruppo Gamma's most recognisable families, with stainless-steel, aged-steel and marine-grade CuSn8 bronze references.
The available selection includes automatic and hand-wound watches, rare limited editions and several dial colours. Browse current stock below, or open the guide for help comparing case materials, movements, dimensions and bronze patina.

The history of the Gruppo Gamma Peacemaker
The Peacemaker was introduced in 2017, but its design originated with an early Vanguard concept developed in 2014 that never entered production. Gruppo Gamma later returned to the idea and shaped it into a separate collection. The result looks back to the simple dive watches associated with military frogmen in the 1940s while using modern materials, construction and the brand's own design details.
Across its generations, the Peacemaker has retained a broad cushion-shaped case, clean fixed bezel, box-shaped sapphire crystal and highly luminous sandwich dial. The collection has appeared in polished steel, aged steel and bronze, as well as special limited editions developed for collector communities. This variety makes “Peacemaker” a family rather than a single specification, so buyers should compare the exact reference rather than relying only on the collection name.
Who is the Peacemaker for?
The Peacemaker suits collectors who want a strong vintage-military aesthetic with the reassurance of a Swiss mechanical calibre. Its 43 or 44 mm case gives it substantial wrist presence, and the 24 mm strap creates a balanced, purposeful profile. It is a natural choice for buyers who enjoy leather or rubber straps, expressive materials and watches that feel less conventional than mainstream dive models.
Choose polished steel for the most versatile appearance, aged steel for a darker industrial character, or CuSn8 bronze if you want a case that changes visibly over time. Automatic movements are convenient for frequent wear, while hand-wound models add a deliberate daily ritual and often display small seconds. Minimal two-hand dials provide maximum simplicity; other references add central or subsidiary seconds.
Swiss automatic and hand-wound movements
Peacemaker references use Swiss ETA or Sellita movements. Automatic models may use the ETA 2824-2, a widely known high-beat calibre that can also be wound by hand. Current bronze hand-wound references such as the PN-19 and PN-20 use the Sellita SW219-1, with hours, minutes and small seconds, a frequency of 28,800 vibrations per hour and approximately 45 hours of power reserve.
The movement affects both the ownership experience and dial layout. An automatic watch winds as the wrist moves, making it convenient for regular use. A hand-wound watch must be wound manually but offers a more direct connection to its mechanics. Always check the product page because limited editions and earlier generations may use a different calibre or movement grade.
Steel, aged steel and CuSn8 bronze
Steel Peacemakers use 316L stainless steel in polished or distressed finishes. Polished cases highlight the flowing shape and pair easily with different straps. Gruppo Gamma's aged finish gives steel a darker, worn appearance without waiting years for marks to develop.
Bronze models use marine-grade CuSn8 bronze. Fresh bronze has a warm golden tone, but exposure to air, moisture and the wearer's environment gradually creates patina. The colour can deepen through brown and other tones, making each case increasingly individual. Patina is a normal surface reaction rather than a manufacturing defect. Bronze can also leave temporary marks on skin, particularly in warm or humid conditions.
Current Mk II models use box-shaped sapphire crystal with anti-reflective treatment, screw-down crowns and 200 metres of water resistance. Sandwich dials place luminous material beneath a cut upper layer, producing depth by day and strong visibility after dark with Swiss Super-LumiNova.

Frequently asked questions
Which Peacemaker is best for a first Gruppo Gamma?
A stainless-steel automatic model is the easiest all-round choice. Choose bronze if the changing patina is part of the appeal, or hand-wound if you enjoy interacting with the movement every day.
What is special about CuSn8 bronze?
CuSn8 is a copper-and-tin bronze associated with marine applications. It develops a natural surface patina that varies with climate, handling and use, so two watches can age differently.
Can bronze patina be removed?
Patina can be reduced or cleaned, but any method should be used carefully and away from the crystal, seals, dial and movement. If you prefer a consistently bright finish, stainless steel is the lower-maintenance choice.
Are all Peacemakers Swiss powered?
The references offered here use Swiss ETA or Sellita mechanical movements, but the exact calibre and grade vary. Confirm the movement field on the individual listing before purchase.
How large does the Peacemaker wear?
Most current models are 43 mm with a 52.5 mm lug-to-lug length and 24 mm strap. The cushion case distributes its visual mass, but this remains a bold watch. Contact us if you would like help comparing it with the 42 mm Vanguard.
Are sold-out models still available?
Availability shown on the product page is current. A sold-out or discontinued reference may occasionally return if an extra allocation or collector piece becomes available, but this is never guaranteed. Join the Mi-Watch private list for selected availability updates.
