What Are Swiss Watch Hallmarks?

The type of metal

The minimum purity guaranteed by law

Purity: 750 / 75% gold

Squirrel

Metal: 14k Gold
Purity: 585 / 58.5% gold

Collectors often encounter this mark on mid-century watches, where manufacturers balanced longevity, affordability, and aesthetics without sacrificing quality.

Duck

Metal: Sterling Silver
Purity: 925 / 92.5% silver

Metal: Platinum
Purity: 950 / 95% platinum

The chamois hallmark signifies 950 platinum, the industry standard for platinum watch cases. Platinum is exceptionally dense, durable, and corrosion-resistant, making these cases rare and highly collectible.

Understanding Gold Purity in Swiss Watches

Gold purity is measured in carats, with 24k representing pure gold. Because pure gold is too soft for practical use, it is alloyed with other metals to improve strength and modify color.

18K Gold (750)

Gold content: 75%

The modern luxury benchmark. 18k gold offers unmatched warmth, weight, and prestige. While softer than lower-carat gold, its richness makes it the preferred choice for high-end Swiss watches.

14K Gold (585)

Gold content: 58.5%

Stronger and more scratch-resistant than 18k gold, 14k was a favorite in vintage Swiss watch production. Its durability made it ideal for daily wear while still maintaining a luxurious appearance.

9K Gold (375)

Gold content: 37.5%

The lowest gold content legally considered solid gold. Due to its high copper content, 9k gold often displays a rosier tone and was especially popular in certain export markets.

Silver Standards Used in Swiss Watch Cases950 Silver

Silver content: 95%

875 Silver

Silver content: 87.5%

A practical alternative to sterling silver, offering similar durability and appearance at a slightly lower purity.

800 Silver

Silver content: 80%

Once the minimum legal standard in Germany, 800 silver was widely used across Europe and remains common in early Swiss wristwatches.

Platinum Standards in WatchmakingPt950

Platinum content: 95%

The benchmark platinum alloy for watch cases. The remaining 5%-often ruthenium or cobalt-significantly affects durability and machining precision.

Pt900

Platinum content: 90%

Less common but occasionally seen in vintage pieces. Visually similar to Pt950, though slightly less pure.

Poinçons de Maître: The Case Maker's Signature

In 1926, Switzerland introduced a discreet identification system for precious metal case manufacturers. Rather than using names or logos, each case maker received a numbered symbol inside a specific outline, stamped inside the case.

These marks, known as poinçons de maître (master's punches), allowed authorities to identify the responsible case maker without undermining the branding of luxury watch companies. When multiple manufacturers shared the same symbol, a unique number distinguished each one-these are called collective responsibility marks.

For collectors, these stamps provide an additional layer of authentication and historical insight.
