About Our Editorial
The editorial section collects what we have learned over more than 30 years in the watch and jewellery trade. The aim is to set out, with concrete examples, the questions worth asking before you buy, sell or trade a piece. Articles cover reference comparisons, condition and authenticity checks, how box and papers affect value, and how the pre-owned market in Istanbul actually works.
Guides and Reference Reviews
Our buying guides work through a single model family reference by reference: case size and material, dial variations, bracelet and clasp details, movement changes, and how each of these is reflected in pre-owned value. Across iconic lines from Rolex, Patek Philippe, Audemars Piguet and Cartier, we explain which details drive collector interest and which condition markers move the price.
The Pre-Owned Market and Valuation
Pre-owned prices are the combined result of brand heritage, the rarity of a reference, current demand, condition and set completeness. Our articles take each of these factors in turn, so you can read the value of a piece for yourself. If you would like a current assessment of your own piece, send the brand, model and condition through our sale request form; our team will come back to you within 24 hours.
