Choose magnification together with lighting. If you cannot comfortably see the screw slot, increasing magnification alone may leave the work darker or too close to your face.
| Question | Why it matters |
|---|---|
| Can I see the working edge with my hand in place? | The useful view is the view during the task |
| Can I move the lamp without moving the watch? | Different surfaces reflect light differently |
| Is the working distance comfortable? | The loupe must suit the space needed by your tools |
| Is there glare from the crystal or dial? | More light can make reflections worse |
| Can I take the loupe away easily? | Inspection and assembly need different views |
Arrange the light first
Use room lighting so the bench is not a bright island in a dark room. Aim an adjustable task lamp across the work, then move it until reflections no longer cover the area you need to inspect. Avoid placing a lamp where it can be knocked into the parts tray.
Choose a view you can work in
A magnifier's stated power is only part of the decision. Check the working distance and field of view in the maker's information. A view that is useful for inspecting a damaged screw may be awkward for turning a screwdriver. If possible, assess comfort before committing to a particular loupe style.
Do not regard discomfort as something to work through. Stop, change position and adjust the setup. HSE recommends changes of activity and looking away during sustained screen work; those are sensible prompts to avoid remaining fixed over close work, rather than a clinical prescription for watchmaking.
Before you order
Check whether the lamp needs a clamp or free-standing base, whether the arm reaches your mat and whether a magnifier can be used with your glasses. Keep its power supply and cable outside the area used for tools. Then revisit the bench layout with the actual lamp position in mind.
