This is the Vacheron Constantin Patrimony Extra-Thin Ref.33060.
With a white dial, silver case and bar indexes, it follows the classic style of a dress watch, but when you look closely at the details, you'll see that it's a very deep model.
First of all, the case material is white gold.
The appeal of white gold is its deep metallic shine that is different from that of stainless steel, and it gives off a sense of luxury and fine texture, which is a major difference from stainless steel.
In fact, it is heavier than stainless steel, weighing 1.5 times as much.
What's particularly noteworthy about this Vacheron watch is the use of the Sigma mark.
At the 6 o'clock position there is a sigma mark 'σ/σ' on either side of SWISS, which indicates the country of manufacture.
This notation can be seen on watches from around 1973 to around 2000, and was used by manufacturers that belonged to an organization called APRIOR.
This is a quality standard created by the Federation of the Swiss Watch Industry in 1973, which states that "when precious metals such as gold are used in watch parts (indexes and dials), this mark indicates that the watch is a high-end, high-quality Swiss-made watch."
This feature can be found in watches from six companies: Rolex, Patek Philippe, Vacheron Constantin, IWC, Omega, and Jaeger-LeCoultre, but it is not present in all watches made during this period.
For this reason, Sigma dials are highly valued for their rarity.
Also, please take a look at the shape of the index. Only the 12 o'clock and 6 o'clock positions are Roman, while the rest are diamond shaped.
Instead of the usual bar indexes, the indexes are diamond-shaped, giving the watch a stylish and sophisticated impression, and the fact that only the 12 and 6 o'clock positions are Roman is also fashionable and shows good taste.
