New model 33 mechanical watch, featuring the original Swiss ETA 2671 movement. The case is set with 54 pieces of VS1.5 natural diamonds and is certified by GTC. While mechanical watches are considered more high-end compared to quartz watches, many people do not fully understand mechanical watches. As a result, they may face more operational or basic knowledge-related issues compared to quartz models. The profit margins for mechanical watches are not as high as those for quartz, making them a less rewarding choice, yet many still prefer mechanical models. This highlights the distinction between practical items and works of art. Both quartz watches and smartwatches are fundamentally practical items. Although these watches, produced through mechanized mass production or modern assembly lines, are all referred to as watches, the divide between art pieces and practical items is stark.We have sold many quartz versions of the Ballon Bleu, and I believe everyone is aware of our quality. You can confidently wear our watches in and out of boutiques without any pressure. Even if you go to a boutique to adjust the length of the strap, the long-term sales staff at the boutique won't be able to tell the difference. So, you can wear it with complete peace of mind!.Additionally, here are some precautions regarding mechanical watches: This model is an automatic winding watch from Cartier, which derives its energy from the movement of the wearer's arm. Therefore, under normal wearing conditions, it does not require manual winding. However, if the wearer's activity level is insufficient to provide enough energy to the mainspring, manual winding may be necessary. This is often a common misunderstanding for those unfamiliar with mechanical watches, who might think there is an issue with the watch.Moreover, to prevent moisture from entering the case and to maintain the waterproof performance of the mechanical watch, please ensure that the crown is securely locked after making any adjustments. It's also important to remember that waterproof watches are only designed for everyday water resistance; they may not withstand hot water, so you might want to look up relevant knowledge on this topic! The watch comes with the highest version of packaging available in the market, comparable to the original packaging, making it a suitable gift!
