Are the Diamonds in high-end watch movements valuable?

Since the appearance of synthetic gemstones in 1892, watch manufacturers have predominantly used aluminum oxide and coloring agents (such as chromium oxide) sintered at high temperatures to form red rubies. However, prior to the 1800s, expensive natural rubies were used in watch movements. Therefore, mechanical watches with ruby bearings were considered high-end timepieces at the time and commanded high prices.

Since most gemstones used in high-end watch movements today are synthetic, does that mean these gemstones are meaningless?

The gemstones used in high-end watch movements typically hold some value, but their worth depends on several factors:

Gemstone Quality: The quality of the gemstone significantly impacts its value. High-quality natural gemstones, such as premium rubies and sapphires, as well as synthetic gemstones like synthetic rubies and sapphires, generally hold higher value. Their clarity, color, and purity directly influence their market worth.

Quantity and Size of Gemstones: The number and size of gemstones used in watch movements also affect their value. Generally, movements with more gemstones and larger sizes tend to have relatively higher value because it implies that the watch manufacturer has invested more cost and craftsmanship into the production process.

Watch Brand and Model: The brand and model of the watch are also important factors in determining the value of gemstones in the movement. Some well-known watch brands and specific models may have higher collector’s value due to their rarity and uniqueness, potentially increasing the overall value of the movement.

Market Demand and Trends: Lastly, market demand and trends also impact the value of gemstones in watch movements. If a certain type of watch or specific brand is favored by collectors or consumers, the gemstones used in them may appreciate in value as a result.

In fact, these gemstones play an irreplaceable role due to their high hardness (Mohs hardness of 9), wear resistance, good surface roughness, and low friction coefficient (friction coefficient generally reaching 0.14 under dry friction when used in conjunction with metal parts, and friction coefficient can be reduced to 0.01 under good lubrication conditions).

When used as bearings in the movement, the transmission efficiency of gears is greatly improved, making the watch more accurate and significantly extending its service life. It can be said that the number of jewels is an important indicator of the quality of a mechanical watch, and the quantity of gemstones is usually marked on the dial.

Therefore, in the past, some watch manufacturers, in order to attract consumers’ attention, marked the quantity of non-functional diamonds (decorative diamonds) on the movement, dial, and case of mechanical watches. This practice, such as having small dials with many diamonds (there are watches with 88 diamonds on the market), is obviously misleading to consumers who are not knowledgeable about watches.

To curb this situation, the international standard ISO-1112 stipulates that only the quantity of functional gemstones can be marked on the dial; regardless of the number of non-functional gemstones, marking is not allowed.

From the above, we can see that the more gemstones used in a movement does not necessarily mean better. The average number of jewels in a typical mechanical watch movement is around 19 (around 25 for automatic mechanical movements). Additionally, if there are other complex mechanisms, the number of jewels in custom-made watches may increase. However, it is certain that the importance of decorative gemstones is slightly lower than that of functional gemstones.

In summary, the gemstones used in high-end watch movements usually have some value, but their specific value depends on the comprehensive impact of various factors.
