Micro-Adjust for Every Watch Strap

Watchmaking is built around precision. Every element is carefully considered.

But for hundreds of years, we've had to settle for 'almost fits.'

Not anymore.

See how it works ↓

Wrists don't come in standard sizes. Watch straps do. One hole is too tight. The next too loose.

Fitwell adds micro-adjustment where straps fall short.

  • Clean integration with any standard strap
  • Installs in seconds with a standard spring bar tool
  • Keeps your watch sitting comfortably all day
  • Solutions for both pin buckles and deployants
  • Works with leather, rubber, or fabric straps

FAQ

What's the difference between the M1 Buckle and the M4 Universal Link?

The M1 Buckle replaces the existing buckle on your favorite straps. It has micro-adjust built in for quick adjustment either on or off the wrist.

The M4 Universal Link attaches between your strap and existing buckle or deployant to add micro-adjust to your strap and closure.

What straps does it work with?

Fitwell works with almost any leather, rubber, or fabric strap that uses a spring bar to attach to its buckle or deployant clasp.

It does not work with metal bracelets.

Does it change the look of my strap?

Not at all. If you use the M1 Micro-Adjust Buckle, your buckle will change but the strap will look exactly as it does today.

If you use the M4 Universal Micro-Adjust Link, you'll keep your existing strap AND buckle or clasp.

Does it require tools?

Fitwell M1 and M4 require no tools to adjust. However, you will need a standard spring bar tool to install them on your strap.

When does the M4 Link ship?

The M4 will ship out mid- to late-February! Pre-order here.
