Add precise, half-hole micro-adjustment to your favorite watch straps. The Fitwell M1 Bead Blasted Titanium replaces your existing pin buckle and doubles the number of usable fit positions - giving you a smooth 3mm “half-hole” adjustment.

If you’ve ever found your watch slightly too tight in warm weather or too loose in the cold, the M1 solves it instantly. No tools. No strap modification. Just a lightweight titanium buckle engineered for daily comfort.

Features

  • Compatible with most leather, rubber, or fabric straps
  • Installs in place of your existing pin buckle - no modification needed
  • Smooth 3mm adjustment, right between standard holes
  • Titanium buckle and tang with stainless-steel spring bar
  • Includes one installed spring bar + one spare

Choosing Your Size

Your Fitwell M1 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 M1 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 M1 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 M1
  • A 22mm strap (at the lugs) tapering to 18mm → choose an 18mm M1

Installation

Two minutes and a spring bar tool

Watch the install before you buy. The buckle or Link goes on with a spring bar tool, and nothing about your strap changes.

Replacing a buckle with the M1

Works as described….. BUT when the clasp is in the smallest position the back part arches up and digs into my wrist. Does not work for me, cool idea though.

Thank you for your review and for trying Fitwell. I'm sorry the back part arches up and digs into your wrist when it's in the smallest position. That's certainly not the experience we strive for or that most of our customers have. Please feel free to contact us directly so we can make it right.

not only did it ar f I've 3 days late. but the instructions shoe a groove on the spring , which would act as a guide for the buckle to insert into the strap holes, but there isn't one, it's a strait pin, also for the price I would think they include a tool to install the buckle. I will not purchase from this company again

It's exactly what you'd expect - and that's great!

All the benefits of a Fitwell M1 in a light weight, matte finish package. Interestingly, the color and texture almost perfectly matches the bead blasted stainless steel case of my Sinn EZM2, so if you have a stainless steel watch this might be a good fit.

Ottimo! veramente comodo la micro regolazione è davvero utilissima

Ho conosciuto questo brand a Ginevra e devo dire che mi ha subito colpito, perché diversi marchi hanno la miro regolazione ma sul deployante, mentre sulla chiusura da ardiglione non l'avevo ancora visto, questo per me è davvero una bella novità

Perfect for my watch

My watch strap is specific to the model it is on. There are no aftermarket straps available and no size options smaller than what is given when buying the watch. Because I have a smaller wrist, I could not get a comfortable fit. This buckle allows me.to get that proper fit. I can wear this watch now!! Thank you!!!

Clever product

A great option for those that are particular about watch fit. Especially helpful for use on larger watches where a loose fitting band is problematic. The titanium buckle may not be as smooth as the steel. Customer service is excellent and ready to address any concerns.
