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

Buckle works as intended. In shortest position the pin of the buckle does not fit inside the groove of the buckle as it does in the longer setting. Due to the angle of the end of the pin the pin sticks up over the buckle in the short position. Does not affect function, but for a $40 buckle this should not be an issue. The concept is elegant, the execution could be more so.
Thank you for the feedback, and we are glad the buckle works as intended! Managing the 'overhang' of the pin while in the short position is challenging and usually has trade-offs (related to appearance vs. micro-adjustment travel). We have tired to go with a middle ground, but we will factor in your thoughts for our future product releases!
I like my watches to fit "just so." Although deployant has a charm to it, the lack of adjustability does not bring joy. With Fitwell, I can use normal straps and get them just so, adjusting through the day as needed. Perfect. The mechanism works great, the quality of the metal looks great too--silver, black, rose gold, gold all look good.
I do have a quick adjust Formex deployant clasp, but the straps needs to be built to specific specs, thus most pre-built straps won't work. Also the "stack" on the wrist of clasp and straps ends up being a bit thick. So I like the simplicity of Fitwell--feels like a normal strap, with a great little twist.
I love Fitwell buckles. I own nearly a dozen of them. They’re quite useful when you need a little breathing room with your strap but don’t need to move to the next hole. You shouldn’t sleep on the fact the buckles themselves are very good looking… my favorite being the titanium.
Functionality is great. Spring bar seems a bit flimsy. Time will tell. At least there’s a spare provided.
These are great—I own 4 already and eventuskly want them for all of my straps.
