Panerai

Panerai has gone from being a niche brand to one that has massive global appeal. You can normally spot one a way off, partly because the case is such a distinctive shape, but also because it occupies a substantial amount of wrist space. As the Italian company continues to thrive, however, Panerais are now available in more modest sizes to fit the more slim-wristed buyer. This one has a 38mm polished steel case. The shock-resistant automatic movement has a three-day power reserve.
