To be a true connoisseur of horology there are a few terms you simply need to understand. A true fan needs to understand the differences between a chronograph and a chronometer, an annual calendar and a perpetual calendar, a flyback chronograph and a double chronograph.
A savvy watch enthusiast also needs to know the prices of wristwatches both on the new and used markets. To snap up a bargain one needs to know the commercial value of said items.
The long term wristwatch lover also needs to establish a collection of reference material – both books in print and marketing/sales catalogues. For the love of fine watches is a life long affair. Beginning with ones first watch and ending with a fine Patek Philippe.
