A portable modular unit for inspecting in a timepiece the presence of a lubricating agent, or of an epilame, having fluorescent markers, from an excitation luminous flux of white light. The modular unit includes an optical housing forming a first module, a portable white light source () emitting an excitation luminous flux forming a second module, and a portable magnifying device forming a third module. The optical housing includes a first mounting interface for removably mounting the portable white light source on the optical housing, the first mounting interface being configured so that the excitation luminous flux emitted by the portable white light source is directed in the direction of the excitation filter; and a second mounting interface for removably mounting the portable magnifying device on the optical housing, the second mounting interface being configured so that the magnifying device is opposite the inspection opening.
