Ralph Lauren Vintage ’67: gold, black lacquer and 90 hours of reserve

Size. Usually the case diameter excluding the crown. Thickness and lug-to-lug distance also affect fit. Rectangular and round watches of the same stated size can wear differently.

Calibre. The name or number of the movement inside the watch. It defines winding, functions and servicing requirements. An in-house calibre alone does not guarantee greater accuracy.

Power reserve. How long a fully wound watch can run without further winding. This is the manufacturer’s stated figure, rather than battery life.

Water resistance. A pressure-test rating, not an approved diving depth. Swimming or diving suitability depends on the model’s instructions and the condition of its seals.

Price. The source currency and market are retained. Shipping, taxes and duties may change the final cost. Without a confirmed price, no estimate is substituted.
