Perlée is the French expression for ''pearl pattern''. It describes a decorative pattern applied by grinding circles on a flat surface - mostly used in the automotive and watchmaking industry. Another French name for this upvaluating processed pattern is ''perlage''. A ground circle is called ''pearl''. Nowadays, the perlée pattern is predominantly applied on parts of wrist watches. The round grinded circles are created by pressing a round rotating abrasive medium on a flat metal surface - freely controlled by hand or precisely by tool machines. ==Perlée in the watchmaking industry== Decorated parts of a watch can be the movement main plate and bridges as well as the inside of the watch case and the watch case bottom as long as it is made from metal. Under ordinary circumstances the decorated parts of a wrist watch remain invisible to the owner. Exceptions are watches with a glass bottom etc. and exposed perlée decorated parts. The perlée decor is nowadays considered as an indicator of a luxurious watch - especially if it is applied completely by hand. The master watchmakers of the olden days tried to invent new grinding patterns. One is called the ''clavus'' pattern or in French language ''oeil-de-perdrix''. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Perlée」の詳細全文を読む スポンサード リンク
