This pocket-sized brass caliper is perfect for measuring wristwatch interlug strap width. Measure up to 100 mm using the large jaws and up to 4 inches using the smaller jaws.
Each caliper is machined from two monoblock pieces of unfinished brass. Scales and markings are engraved directly in the brass. Minor imperfections such as scratches and patina give each caliper its own unique vintage aesthetic.
