Adria and Adriatica are parent Swiss watch brands manufacturing for Eastern European markets.

From 1962 two associated watch companies, established in Biel/Bienne and Basel, took over the manufacturing and marketing of Adria and Adriatica watch in partnership, designing mainly classical round pink gold-plated ladies’ and some gentlemen's models, and a special model called "Adriatica World Champion".

Adriatica watches started being increasingly imported discreetly into Poland by seafaring people and being distributed there and in many of the non-communist countries, becoming established in the Eastern part of Europe.

In 1989, foreseeing the opening of trade, a family who owned the company as of 2013[update]—took over the brands and developed them as manufacturers and distributors.

Since 1998 they have been manufactured by their own company, PR & A Watch Sagl, in Dongio, in the watchmaking area of Ticino, the Italian-speaking part of Switzerland.
