Plastic Watchmakers Eyeglass 2.8X Magnification loupe tool

We turn the body of our 4422-3.5 eyeglass in lightweight plastic to rest directly in the orbital socket. A 22 mm mineral glass lens provides 2.8x magnification for general movement assembly and inspection. Keeping magnification moderate preserves focal depth across the movement bridge while leaving both hands free for tweezers and screwdrivers.

Mineral glass optic

The 22 mm optical mineral glass lens gives a flat field of view across the work. The 2.8x power keeps your working distance natural while assembling gear trains and setting balance bridges.

Plastic cup profile

We shape the plastic cup with a broad rim to seat against the brow and cheekbone. The lightweight body stays put without excessive facial tension while you lean over the movement holder.

Threaded retaining ring

An inner screw ring secures the glass inside the bezel. You can engage the notches with your tweezers to unscrew the ring, allowing you to lift the lens out for thorough cleaning or replacement.

Bench magnification choice

Catalogue 4422-3.5 represents our number 3.5 optical sizing. Choosing only as much magnification as the operation requires keeps your field wide enough to track hand movements without losing orientation on the plate.
