Details and specifications
Fine-tune your watch strap with the Fitwell M1 Micro-Adjust Buckle. Its two-position mechanism adds a 3 mm adjustment between your strap’s existing holes, helping you find a comfortable fit as your wrist changes throughout the day.
In stock and available to order from DougFNJ Watches, an authorized U.S. Fitwell dealer. Select your finish and buckle-end size above. Stainless steel $40; titanium $50.
How the Fitwell M1 micro-adjust buckle works
- Replaces a compatible conventional pin buckle on most leather, rubber and fabric watch straps.
- Adjust the fit without tools after installation; no extra strap holes are needed.
- Choose 316L stainless steel or titanium, with the finish and buckle-end width shown in each variant.
- Includes an installed spring bar and one spare.
Choose the correct buckle-end size
Find your buckle-end size
Use the on-screen sizing tool here at DougFNJ Watches. If the interactive tool does not load, measure the width of your strap where it attaches to the buckle with a millimeter ruler or caliper. Choose the matching 16, 18 or 20 mm option.
Measure the buckle end, not the watch lugs. For example, a 22 mm strap tapering to 18 mm needs an 18 mm buckle. Check the available material, finish and size combinations before ordering.
Measure the strap where it attaches to the buckle. Do not select a size from your watch’s lug width alone. Using a ruler or caliper, measure the width of the strap at the buckle end, or the inside opening of your existing buckle. Match that measurement to a 16 mm, 18 mm or 20 mm M1 variant.
| Strap width at buckle | Select M1 size |
|---|---|
| 16 mm | 16 mm |
| 18 mm | 18 mm |
| 20 mm | 20 mm |
For example, a strap that is 20 mm at the watch and tapers to 16 mm at the buckle needs a 16 mm M1. A 22 mm strap tapering to 18 mm needs an 18 mm M1. A straight strap has the same width at both ends. Only the listed finish and size combinations are offered.
Installation and use
Installation requires a spring-bar tool to replace your existing buckle. After fitting, check that the spring bar is fully seated and the buckle is secure. The adjustment is deliberately firm; familiarize yourself with both positions before wearing.
