Best spring bar tools
A spring bar tool is the one tool every watch owner should have. Its forked end compresses the spring bar that holds a strap between the lugs, so you can swap straps in seconds without scratching the case.
What to look for
- A fork end for straps and a pin end for drilled lugs; the best tools have both
- Replaceable tips, because the fork wears and bends
- Swiss-made tools like Bergeon's have finer, harder tips that slip less
- Tape the lugs with low-tack tape the first few times to avoid scratches
Know your lug width first
A new strap has to match the gap between your lugs. Across our catalog the most common widths are 20 mm (49%), 22 mm (17%), 21 mm (11%), 18 mm (7%) and 19 mm (7%). Integrated-bracelet watches usually can't take a standard strap at all.

1.Barton Watch Bands Barton Spring Bar Tool
$15Best for a cheap first tool for strap swaps
Inexpensive stainless tool from a large strap maker that includes spare tips, which matters because tips are the part that wears or bends.
Watch out: A generic budget tool; the fork is not as fine as the Bergeon 6767-F for tight bracelet end links.

- Material
- Stainless steel

2.Crown & Buckle Premium Spring Bar Tool
$20Best for strap changers who want replaceable tips on a budget
Screw-in stainless tips can be replaced when worn, and the 0.9 mm pusher works on drilled lugs.
Watch out: The 1.6 mm fork is wider than Bergeon's 1.2 mm fine fork, so it may not fit tight bracelet end links.

- Fork width
- 1.6 mm
- Pusher tip
- 0.9 mm diameter

3.Bergeon 6767-F Spring Bar Tool
$29Best for the one tool most enthusiasts should own
The fine 1.2 mm fork fits into tight solid end links and between straps and lugs, the 0.8 mm point works on drilled lugs, and both tips unscrew for replacement. Forum consensus treats it as the default enthusiast spring bar tool.
Watch out: Retail prices vary widely ($19.48-$39.95 across Esslinger, Otto Frei, Crown & Buckle and Long Island Watch), and some owners report the fork is still too wide for certain Rolex bracelets.

4.Bergeon 6767-S Spring Bar Tool
$29Best for leather and fabric strap changes
The larger 3 mm fork slips between a strap and the lug and gives more purchase on the spring bar shoulder than a fine fork.
Watch out: The wide fork is generally too big for metal bracelet end links; pick the 6767-F for bracelets.

6.Bergeon 7825 Spring Bar Tweezers
$253Best for tight bracelet end links, including Rolex-style fitments
Compressing both ends at once lets a bracelet drop out without one side springing back and scratching the lugs; retailers describe it as built similarly to the Rolex 3200 tool.
Watch out: Price varies a lot by retailer (Otto Frei $253.11; SEP Tools lists $159.95 but was sold out), and it is overkill for occasional strap changes.
- Type
- Tweezer-style, compresses both spring bar ends at once
- Fork tips
- Extra-fine forks, 1.0 mm
- Min opening
- Fits spring bar openings of 1.0 mm or larger
- Origin
- Swiss made
7.Bergeon 6825 Spring Bar Pliers
$340Best for frequent bracelet swaps on modern sports watches
Otto Frei says it was designed for installing modern bracelets such as Omega's, and the adjustable width lets it be preset to a lug width.
Watch out: Otto Frei states the standard 6825 does not work on Rolex bracelets.
- Type
- Plier-style, compresses both spring bar ends at once
- Width range
- Adjustable 10-30 mm, locks with a screw
- Forks
- Reversible stainless steel, 1.3 mm opening, 0.33 mm tip thickness
- Fork angle
- Notches for 0-45 degrees
- Variants
- 6825-PF fine forks (same price); replacement forks $33.31 each
Worth knowing
- Spring bar tools usually pair a fork (to compress a spring bar from between the strap and lug) with a pin point (to push a spring bar through drilled lug holes from outside the case). (longislandwatch.com)
- Bergeon makes the 6767 in several versions: the 6767-F has a fine 1.2 mm fork suited to bracelet end links, while the 6767-S has a 3 mm fork suited to straps; both have a 0.8 mm pin tip and replaceable threaded tips. (ofrei.com)
- For tight solid end links, forum members recommend a tweezer or plier-style tool that compresses both spring bar ends at the same time instead of a single-ended tool. (omegaforums.net)
- Otto Frei notes that the Bergeon 6825 spring bar pliers do not work on Rolex bracelets; the 7825 tweezers fit spring bar openings as small as 1.0 mm. (ofrei.com)
- Quick-release spring bars have a small lever that lets a strap be changed without tools; standard bars have a shoulder that a spring bar tool's fork catches. (omegaforums.net)
