3" Brass Sliding Gauge Caliper, 80mm Notched Jaws, Dual Scale Inches/Metric, for Watch, Jewellery and Beads

For watchmakers and jewellers needing accurate measurements near sensitive movements, this brass sliding gauge is the ideal bench tool. Its non-magnetic construction prevents interference, ensuring reliable sizing of watch parts, beads, and jewellery findings up to 80mm.

Key features

• Solid brass construction is fully non-magnetic, safe for use near watch movements.
• Dual scale is clearly marked in inches (to 3") and metric (to 80mm).
• Notched jaws are designed for taking both external and internal measurements.
• A simple friction slide with a raised stud allows for smooth, one-handed adjustment.
• Compact 80mm size is well-suited for fine bench work and tool-roll storage.

Who it's for

A workshop essential for UK watchmakers, bench jewellers, and gemologists. Also favoured by model engineers and electronics technicians working with small, magnetically-sensitive components where steel calipers are unsuitable.
