The M2 is firm on purpose: it holds because changing it takes intent. Once you get used to it, you can adjust it on the wrist.

Free US Shipping $50+. Free US Returns/Exchanges.

The Fitwell M2 is just like the M1, but for wider hole spacing or thicker straps. Add precise, smooth "half-hole" adjustment to your FKM Rubber, Tropic-style, and thick leather straps - 4mm of micro-adjust built directly into the buckle. 

Features

  • 4mm of toolless micro-adjust: pull the buckle out to loosen it, press it in to tighten it
  • Two fixed positions, 4mm apart. Firm, so it never moves on its own
  • Fits nearly all standard straps, no modification required
  • The micro-adjust is fully contained within the buckle, 
  • Standard tang / pin included. A wide 2.75mm tang / pin is available for straps with larger holes.
  • 316L stainless steel, installs in place of your existing tang / pin buckle with a spring bar tool.
  • Perfect for Rubber, Tropic-style, and thick leather straps. 

About the pre-order

  • You're charged at checkout. Your M2 ships in February 2027
  • Cancel any time before it ships for a full refund.
  • The pre-order price is for ordering by November 10. Discount codes don't apply to pre-order items
  • If your order also has in-stock items, those ship now and the M2 (and M2 wide tang / pin and spring bar tool, if selected) ships when it arrives.

Choosing Your Size

Your M2 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 M2 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. Choose the M2 size that matches that measurement.

Most tapered straps narrow by 2–4 mm. A 22mm strap tapering to 18mm → choose an 18mm M2.
