This is a universal watch band spring bar set containing 50 pieces of various sizes, ranging from 8mm to 29mm, covering common lengths such as 16mm, 18mm, 20mm, and 22mm. Made of stainless steel, these spring bars offer excellent elasticity and corrosion resistance, used to connect watch straps to the watch case. They are essential basic accessories for replacing worn spring bars or DIY strap changes.
| Note | Details |
|---|---|
| Size Selection | Spring bar length must match lug width. Too short = loose strap; too long = difficult to install and may damage lug holes |
| Quality Differences | Generic spring bars may have lower elasticity and durability than OEM parts – inspect regularly to prevent accidental strap detachment |
| Work Environment | Work on a soft surface to prevent springs from flying away if compressed |
| Regular Replacement | Inspect spring bars annually; replace if rusted, deformed, or weak |
| Water Resistance | Spring bars do not affect water resistance, but a loose strap may cause case impact |
Q1: How do I know which spring bar size to use?
A: Measure the distance between the inside of the lugs (lug width) with a ruler or caliper. Common sizes: 18mm, 20mm, 22mm. Choose a spring bar of the same length or 0.5mm longer for a snug fit.
Q2: Are these spring bars suitable for all watches?
A: They fit most watches with standard lug holes. However, some luxury watches (e.g., Rolex) use thicker spring bars (1.8mm or 2.0mm diameter). Check your original spring bar diameter before ordering.
Q3: How can I prevent spring bars from flying away during installation?
A: Use a spring bar tool with a fork tip, and work inside a clear plastic bag or on a soft cloth. Compress gently and keep your finger over the end to control it.
Q4: Why do some spring bars have double notches?
A: Double-notched spring bars are designed for use with fork-tipped spring bar tools, allowing you to compress both ends simultaneously for easier installation on some bracelets.
Q5: Can I reuse old spring bars?
A: It depends on their condition. If they are not rusted, deformed, or have lost spring tension, they can be reused. However, for critical applications, it‘s safer to replace them.
