Spring bars for watch straps
A spring bar is the small sprung rod that keeps the strap between the lugs of the watch. Its length is the lug width.
What you will find
Rolex-type spring bars, with or without shoulders, and quick-release bars. One pack in your lug width is enough for a watch.
How to choose
Check two things: length, which equals the lug width, and diameter, which has to fit the strap. If the lugs are not drilled through, take a shouldered bar so the tool has something to catch. All types are explained in our spring bar guide.
Questions we often get
Which length do I need? The same as your lug width, so 20 mm bars for 20 mm lugs. Here is how to measure.
How do I know a spring bar is worn out? It is bent or rusty, or the tips no longer pop back out firmly. Replace it.
What tool do I use? A spring bar tool from the bracelet tools page.
