Single Lens Watchmakers Loupe 3.5X

The Single Lens Watchmakers Loupe 3.5X delivers distortion-free magnification in a compact, pocket-sized design built for bench use. Its contoured shape allows the loupe to rest comfortably in the eye socket, freeing both hands for detailed work. The single ground and polished lens is set in a lightweight black plastic frame, keeping fatigue to a minimum during extended use sessions.

With a 3.5X magnification and a 3" focal length, this loupe offers a generous working distance and a wide field of view — ideal for tasks requiring broad visibility rather than extreme close-up detail. The 22 mm lens diameter and 33 mm eyepiece opening provide a clear, comfortable viewing area suitable for watchmakers, jewelers, and metalsmiths alike.

Notes

This is a single lens magnifier. As magnification increases, focal length decreases and the field of view narrows — meaning you work closer to the piece with a smaller area in focus. Conversely, lower magnification (such as 3.5X) provides a longer focal length and a larger field of view. Choose your magnification based on the working distance and coverage area your task requires.
