2.5X Watchmaker Eyeglasses loupe biconvex air 4

We turn this loupe body with a plain flared profile that sits in the orbit of the eye. The biconvex lens gives 2.5x magnification across a broad field, suited for general movement assembly, casing, and checking gear trains under bench light. The body carries catalogue number 2611-TN.

Biconvex lens

We mount a 25 mm biconvex glass lens into the front bezel. The 2.5x magnification brings bridge screws, jewel settings, and wheel teeth into clear focus while leaving ample working distance under the tweezers.

Flared body

The outer wall follows a traditional plain taper. It rests against the brow and cheek without requiring excessive tension from the facial muscles during long spells at the bench.

Air hole

We pierce the side wall with an air vent. This small opening allows heat and moisture to escape from behind the glass so the lens remains clear while you work over a movement.

Bench storage

Keep the glass free of oil mist and bench dust by storing the loupe face down on a clean pad or under a glass bell when the work is set aside.
