Always measure the watch lug width, not the spring bar itself. The correct size is the distance between the inner edges of the lugs where the strap sits. Measuring the spring bar can be misleading because spring bars compress and extend.
Use a digital caliper for the most accurate result. Measure the inside distance between the lugs in millimeters. If you do not have a caliper, a ruler can be used, but accuracy may vary. Always round to the nearest standard size such as 18 mm, 20 mm, or 22 mm.
Spring bars are spring loaded and can appear shorter or longer depending on compression. Measuring the spring bar itself often results in the wrong size. The lug width of the watch case is the only reliable reference.
Thickness depends on the watch and strap.
1.5 mm is ideal for dress watches, vintage watches, and straps with tighter tolerances.
1.8 mm offers increased strength and is recommended for sports watches, tool watches, and heavier straps.
Always ensure your lug holes and strap can accommodate the selected thickness.
Yes. These spring bars are designed with precise tolerances to fit both standard lug holes and solid lug hole cases. For solid lug watches, always verify that the lug hole diameter supports the selected thickness before installation.
No. Many spring bars look the same on the outside, but the quality can be completely different. Cheap spring bars are often made from low grade steel with weak springs, while premium spring bars are made to manufacturer and Swiss standards.
Yes. Spring bars hold your watch on your wrist. Low quality spring bars can bend, lose tension, or break over time, which can cause your watch to fall and get damaged. A broken spring bar can cost far more than a proper high quality replacement.
High quality spring bars are made from 316 stainless steel, use stronger internal springs, and are tested for tension and durability. They resist corrosion, keep their strength over time, and provide much better security for your watch.

How to Measure a Watch Strap :
Remove the Strap (if needed):
- Take off the watch strap if it is still attached. This ensures precise measurement of the lug width.
2. Locate the Watch Lugs:
- The lugs are the small metal bars or openings on the watch case where the strap attaches.
3. Measure the Lug Width:
- Place the ruler across the inside of the lugs.
- Measure the distance between the two inner edges of the lugs (in millimeters).
4. Determine the Strap Width:
- The strap width should match the lug width to fit securely.
- For example, if the lug width is 20 mm, you need a strap that is also 20 mm wide.
💡 Pro Tip: Use a precision ruler or caliper for the most accurate measurements.
