Buying a mechanical watch is both a rational consumption and an emotional investment. Clarifying the budget, choosing a reliable brand, and paying attention to the movement and appearance materials are the keys to ensuring that you buy a satisfactory watch. At the same time, choose the function and waterproof level according to your own usage scenario to avoid excessive pursuit of complex functions that will lead to a burden of later maintenance. Purchase through formal channels, keep the warranty card and invoice well, and future maintenance and resale will be more secure. Only by rational selection can you truly enjoy the long-term companionship brought by the beauty of machinery.
