QR Code Link to This Post
For sale is an authentic, highly collectible vintage parallel watchmaker balance truing caliper (traditionally known as a "Huit-Chiffre"). Manufactured by L.C.R., this is their famous "Junior" model, designed specifically for fine precision testing, leveling, and truing of mechanical watch balance wheels.
Features & Details:
• Premium Brand Branding: Stamped with sharp, clear "L.C.R." and "JUNIOR" hallmarks on the face arches.
• 100% Complete Index Attachment: Features the original, fully adjustable slotted index arm with the fine alignment pointer assembly. Because these sliding indicators were detachable, they are usually missing on the secondary market—finding a complete L.C.R. unit like this is rare.
• Flawless Mechanics: The central knurled thumbwheel spins smoothly on the brass threaded rod to micro-adjust the parallel alignment jaws evenly.
• Bench-Steady Design: Features the dual stabilizer support pins along the spine so the tool rests completely flat on your workbench while spinning a balance wheel.
An exceptional piece for practicing horologists, vintage tool collectors, or anyone wanting a top-tier brand on their watch repair bench.
