Great Service w/ boywithakoi

Pat was incredibly helpful throughout the process. I bought a Rolex Submariner 14060M, and he addressed all of my questions. The watch arrived on time, in great condition, and unpolished, just as described. He has definitely earned my trust, and I'll gladly do business with him again in the future.

Longines (French pronunciation: [lɔ̃ʒin], lawn-zheen) is a watch company based in Saint-Imier, Switzerland. Founded by Auguste Agassiz in 1832, it is currently owned by the Swatch Group. Its winged hourglass logo is the oldest registered trademark for a watchmaker.

Based in Saint-Imier since 1832, the Compagnie des Montres Longines Francillon S.A. was among the world’s leading watch companies. In 2007, Longines had its 175th anniversary. The brand evolved from a comptoir to a full-fledged manufacturing operation and then back down to an établisseur today, since the early 1980s, as a Swatch Group company.
