The in-between problem

One hole pinches. The next one slides.

Between those two holes is where your watch actually fits. Bracelets solved this years ago with micro-adjust clasps. Fitwell brings the same precision to straps: 3mm of adjustment at every hole, exactly half a hole, doubling the positions of any strap.

Two ways in.

Fitwell M1 Micro-Adjust Buckle
For straps with a pin buckle

M1 Micro-Adjust Buckle

  • Replaces your pin buckle. No bigger than the original
  • Adjusts with a click, on or off the wrist
  • 316L stainless steel or titanium. Seven finishes

For deployants, or a buckle you're keeping

M4 Universal Link

  • Fits between your strap and its closure. Nothing swapped
  • The only way to add micro-adjust to a deployant
  • 3mm thick, thinner than some straps. Four finishes

Both install with a standard spring bar tool in about two minutes, on leather, rubber, or fabric straps. Not sure of your size? The Fitwell Size Finder sorts it in under a minute.

“Just ordered six more”

I ordered a couple recently and tried them for a few days… then I ordered six more.

Amazing. I am a bit OCD about strap fit… this works perfectly.

It made the watch I didn’t wear anymore, because the strap didn’t fit well, a favourite again.

I cannot believe no one has ever thought of micro-adjustment for a basic watch buckle before. Well-made, looks first class, and most importantly, works.

The trade agrees: Delugs builds the Fitwell mechanism into its CTS deployant, and Awake and Sherpa ship Fitwell as standard hardware. Read the reviews ›
