Watches
When coating watches with precious metals, performance matters as much as appearance. Scratch resistance, lightness, and dimensional stability depend on precise, non-destructive analysis of alloy composition and coating thickness to ensure reliable quality. Are you ready to discover how our solutions support you?
Solve it with Fischer!
When coating watches with precious metals, PVD or CVD coatings, it is not only aesthetics that play a decisive role, but also properties such as dimensional stability, lightness or scratch resistance. Fischer XRF and tactile instruments allow you to non-destructively analyze precious metal alloys or the thickness and composition of the thinnest coatings, thus ensuring the quality of your watches.

Gold and precious metals in soils, ores, and as nuggets
Analyzing soil and ore is a crucial step in mining exploration. Highly sought-after resources such as gold, silver, and other precious metals often occur only in trace amounts or within complex rock compositions, making them difficult to identify. Sometimes, naturally formed gold nuggets are found. In these rare cases, reliable testing of their authenticity and purity is essential for assessing their value and selling or processing them further. Are you facing this challenges too?
