Let me answer you, there is no Vacheron Constantin watch chain without letters, all with letters. Because I went to Switzerland to buy a watch for my dad. ?The Vacheron Constantin straps are engraved with: Vacheron Constantin, Vacheron Constantin, and the letters on the back of the watch are STAINLESS STEEL BSCK F4 WATER RESISTANT 3ATM?. Vacheron Constantin’s logo: the Maltese Iron Cross. Vacheron Constantin only produces more than 20,000 watches every year. This is like OPEC imposing crude oil production limits and thereby raising oil prices. Of course, there are differences between Vacheron Constantin and Croton. Crude oil is a mass consumer product, and Vacheron Constantin is a work of art for the aristocracy. It is worth admiring that Vacheron Constantin has spent 240 years. The watchmaking industry is the most important industry in Switzerland. Whether in the past or today, Vacheron Constantin has always played a key role in the history of the Swiss watchmaking industry.
