I always believed that when you buy a luxury item you are first and foremost buying history and legacy. This surely applies to vintage watches. Wearing a 50 year old beautiful watch is a powerful statement and clearly defines a personality that believes in heritage, history and a passion for things well done.
I personally have a preference for 2 brands: IWC and Patek Philippe. Both of them have passed the test of time and have always been at the forefront of the best Swiss technology and tradition. It’s a very difficult task to find the right piece at the right price, but research definitely helps in making the right purchase. Always remember to buy from a reputable dealer and don't forget to choose a cool strap!
