Add seamless micro-adjustment to your existing deployant or buckle. The Fitwell Micro-Adjust Universal Link gives you the same on-the-fly comfort as our integrated Fitwell buckles, now in a compact inline form that installs easily between your strap and existing closure.

If you’ve ever found your watch too tight in warm weather or too loose in the cold, this is your fix. It adds precise, wrist-adjustable sizing without tools or strap modification.

Features

• Works with both deployant clasps and pin buckles
• Compatible with most leather, rubber, or fabric straps
• Adds up to 3mm of micro-adjustment for perfect daily comfort
• Adjusts easily on the wrist - no tools required
• Crafted from 316L stainless steel
• Includes spring bars for quick installation

How It Works

The Universal Micro-Adjust Link connects between your clasp and strap, extending or shortening the strap by up to 3mm with a simple slide mechanism. It effectively doubles the number of fit positions available, allowing you to fine-tune comfort throughout the day.

Choosing Your Size

Your Fitwell Link size is based on the width of your strap at the buckle - not the lug width of your watch.

If your strap is straight (non-tapered):
Select the Link size that matches your lug width.

If your strap tapers toward the buckle:
Measure the width of your strap at the buckle end, or the inside width of your current buckle, using a ruler, tape measure, or caliper.
Choose the Link size that matches that measurement.

Most tapered straps narrow by 2–4 mm.

Examples:

• A 20mm strap (at the lugs) tapering to 16mm → choose a 16mm Link
• A 22mm strap (at the lugs) tapering to 18mm → choose an 18mm Link
