Introduction — The 0-150 mm electronic digital caliper is a precision instrument indispensable to any watchmaker or jeweller. Its LCD reads to a hundredth of a millimetre and switches to inches with a single tap on the mm/in key.
Product overview
The body is treated stainless steel with ground rails and constant-friction slide. The inner and outer jaws are V-cut so they grip a lug hole or a spring bar diameter equally well. The depth rod lets you record the thickness of a case-back or the usable length of a crown stem.

FAQ
How do I replace the battery?
Slide off the cover above the screen and replace the SR44 cell observing + polarity.
Can I measure lug-to-lug width?
Yes, by placing the outer jaws against the inner faces of the lugs.
Is the instrument waterproof?
No. Avoid prolonged contact with liquids or solvents; wiping dry after use is enough.

We pay special attention to packing: every tool is wedged in bubble wrap or a fitted carton to avoid any mark in transit. If you are unsure about compatibility with your watch, please email our technical desk with brand, model and lug width in millimetres: we reply within 24 working hours.
We also stock a complete range of complementary consumables: spring-bar assortments, split-pin sets, Viton-grade o-rings, polishing compounds and SR, CR or LR format batteries. Those references can be added to your cart to share shipping cost. Our logistics favours recycled cardboard packaging and our plastic boxes are returnable when applicable. A watchmaker investing in tooling does so for several years: our products are picked accordingly, with a brief that prioritises manufacturing consistency over the cheapest price.
