Technical tips

- Work on a soft surface to avoid scratches.
- Prefer a brand-new spring bar every time you change the strap.
- Once fitted, give the strap a gentle pull to check the bar holds.
5 minutes is on average all it takes to change a strap with the right tool.

Common mistakes

- Forcing the spring bar: it bends or snaps.
- Re-using a tired spring bar: the strap can drop off.
- Picking a spring bar that is too short: it will not hold.
FAQ
Which spring bar fits my watch?
Measure the lug-to-lug width and the hole diameter. See our guide how to choose a spring bar.
Do I need a new spring bar every time I swap straps?
Yes, ideally — the internal spring weakens over time.
What if I don't have a spring bar tool?
A fine pair of tweezers or a straightened paperclip will do in a pinch, but the dedicated tool remains the right one.
