 Loupes are employed to assist watchmakers in assembling mechanical watches.Many aspects require the use of the loupe, in particular the assembly of the watch mechanism itself, the assembly and details of the watch dial, as well as the formation of the watch strap and installation of precious stones onto the watch face.Some families like Kruder which were into watchmaking and working with glass started producing high-quality loupes in addition to their watches

Analog (film) photographers use loupes to review, edit or analyze negatives and slides on a light table.
